Abstract: A hydraulic system with an adjustable hydrostatic machine is provided that includes an adjustment mechanism. The adjustment mechanism interacts with an actuating device which has at least one actuating piston delimiting an actuating pressure space. The system has a regulating valve with which, for the displacement of the actuating piston and therefore for the actuation of the adjustment device, the supply and removal of pressure medium into and from the actuating pressure chamber can be controlled, wherein the regulating valve has a valve piston which is subjected to a force of a feedback spring, which force is dependent on the position of the adjustment mechanism. The valve piston is additionally subjected to a counterforce acting counter to the force of the feedback spring, and an actuating component is provided, with which the valve piston can be subjected to a control force acting in the same direction as the counterforce or to a control force acting counter to the counterforce.

Abstract: The invention relates to a hydraulic motor unit comprising a hydraulic motor (1′) which is connected to two working lines (3, 4). The swiveling angle (α) of the hydraulic motor (1′) is adjusted by means of an adjusting unit (7) which is provided with a regulating piston (8) comprising two piston surfaces (9, 10). The regulation pressure acting on a first piston surface (10) in a regulation pressure chamber (12) can be adjusted by means of a control valve (13). Said control valve (13) adjusting the regulation pressure is movable between two final positions. The pressure of a working line (3, 4) is applied to a first measuring surface (23) of the control valve (13) adjusting the regulation pressure while a second, opposite measuring surface (25) of said control valve (13) is impinged upon by a control pressure piston (34) at a force that depends on the control pressure only once a threshold value of a pipe (28, 18′) supplying control pressure has been exceeded.

Abstract: A compressor includes swash plate, which is tiltably supported by a drive shaft. The displacement of the compressor changes in accordance with the inclination angle of the swash plate. The minimum inclination angle (&thgr;min) of the swash plate is less than three to five degrees relative to a plane perpendicular to the axis of the drive shaft. The swash plate can be moved from its minimum inclination to increase its angle, despite the small minimum inclination angle, due to a return spring, which urges the swash plate to increase the inclination angle. The return spring positively moves the swash plate in a direction increasing the inclination angle.

Abstract: A peristaltic pump for propelling liquid through a flexible tube segment. The pump has a cam shaft which carries a plurality of cams each having a driving surface. The driving surfaces of adjacent cams are spaced at an angle to each other about the cam shaft. The pump also has a plurality of cam followers which are each reciprocal in a common direction perpendicular to the axis of the cam shaft. Each cam follower has a cam surface riding on the driving surface of a cam and a tube engaging surface for engaging the flexible tube segment. At least one of the cam followers is a restriction cam follower of which the tube engaging surface engages the flexible tube segment for a longer period than that of the other cam followers. The pump also has a motor for rotating the cam shaft whereby the cams cause the cam followers to each engage and occlude the flexible tube segment to form a propagating depression wave in the flexible tube segment for propelling liquid. The restriction cam followers prevent back flow of the liquid.

Abstract: A controller, for a variable capacity pump, prevents engine stalls due to rapid changes in operating load by increasing the pump absorption torque when the engine speed is high so as to increase the work amount and by reducing the pump absorption torque when the engine speed is low. The controller receives a signal from an engine speed sensor for detecting engine speed. A pump absorption torque curve is pre-set so as to be consecutively stepped with respect to engine speed so as to intersect at an engine rated point. The pump absorption torque is then calculated in accordance with increases or decreases in engine speed. The pump absorption torque is then set to prescribe values based on the results of these calculations and an instruction is outputted to a control valve in such a manner as to regulate a regulator of the variable capacity pump.

Abstract: A variable displacement axial piston hydraulic unit includes first and second control pockets individually disposed between first and second arcuate shaped fluid passages, a first electrohydraulic valve for controlling fluid flow between the first control pocket and the first fluid passage and a second electrohydraulic valve for controlling fluid flow between the second passage and the second control pocket. A controller outputs first and second control signals to the first and second electrohydraulic valves in response to receiving a command signal so that the tilt angle of a swashplate is controlled to obtain a desired operating parameter. An angle detector, a pressure detector, and a speed detector provide feedback signals to the controller for determining when the desired operating parameter has been obtained.

Abstract: A variable capacity wobble plate type compressor having a non-rotatory wobble plate supported on a magnetic material support member to non-rotatively wobble to move compressing pistons in cylinder bores, a steel drive shaft driven by a drive source via a solenoid-operated clutch and causing the non-rotative wobble of the wobble plate at a given angle of inclination that is changed to vary the capacity of the compressor, and a capacity detecting unit provided with a permanent magnet attached to an outer periphery of the wobble plate, a magnetic sensor fixedly attached to the crankcase of the outer casing, for sensing an approach and departure of the permanent magnet of the wobble plate. The magnetic sensor generates electric signals indicating the approach and departure of the permanent magnet of the wobble plate, and a binary circuit electrically connected to the magnetic sensor converts the electric signals of the magnetic sensor into electric binary signals by which the capacity of the compressor is determined. The capacity detecting unit is also provided with an arrangement wherein a magnetic flux delivered from the permanent magnet flows in a direction opposite to that of a magnetic flux leaking from the solenoid-operated clutch through the drive shaft and the support member to prevent erroneous electric binary signals when the permanent magnet attached to the wobble plate is close to the magnetic sensor.

Abstract: A wobble plate type compressor is equipped with a device which can be selectively activated in a manner to induce the wobble plate to assume a position wherein the displacement of the compressor is reduced to zero and thus obviate the need for a clutch for such purposes. The device further includes an arrangement which biases the wobble plate toward a position wherein a positive displacement of the compressor will occur when in a non-activated state. The strength of this bias is insufficient to interfere with the control of the wobble plate inclination by the pressure prevailing in the chamber in which the plate is disposed.

Abstract: A wobble plate compressor which is adapted to vary the angularity of the wobble plate during rotation in response to the difference between the resultant reaction force exerted by the pistons on their compression and suction strokes and the pressure in the crankcase. The compressor has a passage with an orifice communicating a lower pressure space therein with the interior of the crankcase, a communication passage communicating a higher pressure space therein with the interior of the crankcase, and a control valve means for controlling the opening of the communication passage. Preferably, the cross-sectional area of the above orifice passage is set at such a value as to permit blow-by gas leaking from the cylinders into the crankcase to escape from the crankcase into the lower pressure space at a flow rate at least equal to the maximum possible flow rate at which the blow-by gas leaks from the cylinders into the crankcase.
