Abstract: A variable capacity wobble plate compressor of the type that a wobble plate mounted on a drive shaft is swung axially of the drive shaft as the drive shaft rotates, and pistons connected to the wobble plate make reciprocating motions in response to swinging of the wobble plate, wherein a change in the angularity of the wobble plate causes a change in stroke of the reciprocating motions of the pistons whereby the capacity of the compressor is varied. A sensing element arranged on the wobble plate is moved along a predetermined orbital path together with swinging of the wobble plate. A sensor arranged on a compressor housing generates an electric signal when the sensing element passes by the sensor as the wobble plate swings. A control unit determines the rotational speed of the compressor and the angularity of the wobble plate on the basis of the electric signal from the sensor. The sensor is so located as to align with a predetermined location between an axial center of the predetermined orbital path of swinging of the sensing element and an extreme possible point toward the pistons, when the wobble plate assumes the minimum angularity.

Abstract: Disclosed is a device for controlling or measuring operational parameters of an axial piston machine. The tilting plate which engages and adjusts the stroke of the piston is provided with two opposite pivot pins supported in fixed bearings. At least one pivot pin is provided with a shearing stress sensor preferably in the form of a magnetoelastic feeler which produces electrical signals the pulsation of which is indicative of rotational speed and the magnitude of the signal is proportional to pressure applied by the pistons and thus to the delivery of the machine. A second sensor is coupled to the tilting plate to indicate the angular displacement of the latter. The output signals from the sensors are separated into the pressure dependent signals, frequency dependent signals and angular displacement signals which upon multiplication are applied to a programmable data processing unit. The output of the unit is supplied to a solenoid operated proportional valve which controls pressure fluid for hydraulic setting motors which adjust the angular displacement of the tilting plate.

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.
