Abstract: A brake pressure control system for braking systems of a vehicle with anti-locking and drive slip control in which there is at least one expansion chamber provided between the wheel brake cylinders and the recirculating pump. The expansion chamber includes an inlet and an outlet on the same end with a piston having a closing mechanism thereon that is spring forced to seat the closing mechanism on a seat at the outlet. The valve seat is reduced in size compared with the piston and the spring is in a chamber which is open to the atmosphere. Due to the valve seat being reduced in relation to the area of the piston located in the expansion chamber, a steep closing force gradient is achieved, since even small pressure differences result in large closing force differences, so that the opening and closing pressures lie close together. Based on this additional closing mechanism, provided on the expansion chamber, the requirement for a separate valve for brake pressure control is no longer required.

Abstract: The invention is directed to improving the performance of a reciprocating piston pump in terms of noise. The reciprocating piston pump has a drive shaft, which has a circular cylindrical swash member, which is set at an acute angle (.beta.) to the longitudinal axis (O) of a pump and has a circumferentially disposed roller bearing ring. A pump piston, with its end face embodied as part of a spherical surface, engages the circumferential face of the roller bearing ring of the swash member. The longitudinal axes (O, P) of the drive shaft and pump piston extend in the same plane and intersect at right angles. The longitudinal axis (O, T) of the drive shaft and swash member are also offset from one another. Because of this configuration, a pumping phase that is considerably longer than the intake phase during one pumping cycle is attained. Changes in pressure andd force therefore proceed more slowly in the lengthened pumping phase, which improves the noise performance of the reciprocating piston pump. The reciprocating piston pump can for instance be used in vehicle brake systems to pump brake fluid.

Abstract: A control valve for maintaining the temperature respectively the viscosity of pressure fluid passing therethrough substantially constant comprises a control slide provided with a throttle bore and downstream of the control slide a precontrol valve in which an end portion of an element expandable by the temperature of the pressure fluid is arranged. When pressure fluid with a certain pressure is fed through the inlet end of the control valve, the control slide is lifted from its seat and the precontrol valve opens. All of the pressure fluid entering the control valve is passed through various bores and annular gaps along the precontrol valve to the temperature expandable element. When the fluid reaches the desired maximum temperature a bypass for the fluid is created by the expandable element and a control pin actuated by the latter. Thereby the throttle action of the control valve is reduced and overheating of the pressure fluid avoided. A throttle gap between the control slide and the housing will assure removal of any air contained in the pressure fluid and a further throttle gap formed between an end face of the control slide and a disc attached thereto serves to catch any foreign particles in the pressure fluid which will be flushed away after moving of the control slide away from its seat.

Abstract: The invention relates to a device for a hydraulic unit, in particular in anti-skid systems for vehicle brake systems, which has a radial piston pump. The eccentric driven by a drive shaft in the pump meets pump pistons also located in the pump, usually in the region of high stroke variation speed. An resultant mechanical and hydraulic vibration, which causes noise and annoying movement at the brake pedal, is counteracted according to the invention in that a resilient intermediate element is disposed between the pump pistons and the eccentric element, and the eccentric is driven via a torsionally elastic coupling.

Abstract: The pump having a housing with a bore for receiving a pump cylinder having a pump piston, which is drivable by a cam. An outlet valve housing is disposed, coaxially with the cylinder, in an enlarged portion of the bore. An annular chamber formed thereby encompasses the outlet valve and is closed off by a cap. The pump piston cylinder, the outlet valve and the cap are retained by a closure screw in the pump housing, which screw is screwed into the bore portion. In combination with a pump outlet bore embodied as a throttle, the annular chamber acts as a damper chamber for the brake fluid that in this type of pump is pumped discontinuously. Because of the damper chamber and pump outlet bore, pressure vibrations of the brake fluid reduced, and an impetus toward vibration of the vehicle body during a pump operation is avoided, so that noise generation in the interior of the vehicle is largely suppressed.

Abstract: The valve for a pressure-medium-operated hydraulic arrangement has a housing provided with an inlet and an outlet, a slide piston located downstream of the inlet and seal-tightly movable in an opening of the housing under the action of the pressure medium entering the same so as to subdivide the pressure medium into a first stream flowing directly to the outlet and a second constant stream, a laminar throttle member located downstream of the slide piston and associated with a spring-biased control member wherein the laminar throttle member and the control member are arranged so that the constant stream flows through the laminar throttle member and generates pressure drop which acts upon the control member against its bias, and the control member subdivides the constant stream into two partial streams which flow to the outlet means and one of which is throttled, whereby the pressure drop between the inlet and the outlet is maintained at a constant level and thereby the viscosity of the pressure medium is maintained constant.

Abstract: The hydraulic lifting device for harvesting machines includes a hydraulic cylinder-piston unit mounted on the wheel frame of the machine and supporting most of the weight of the harvesting apparatus so that the latter abuts against the ground with residual weight only. The cylinder-piston unit is controlled by a multi-way selector valve and a locking valve unit connected in a first working pipeline system. The hydraulic device further includes a pressure limiting valve for setting a reference pressure for the hydraulic cylinder-piston unit, the limiting valve being connected in an additional working pipeline that is branched upstream the limiting valve to a nonreturn valve and therefrom is connected by a direct conduit to a hydraulic accumulator and the hydraulic cylinder-piston unit. The combination of the pressure limiting valve with the non-return valve and the branch conduit prevents during the lowering of the piston-cylinder unit the hydraulic accumulator from being completely discharged, accelerates the lowering movement and improves the seal of the entire lifting device.
