Abstract: Proposed is a hydrostatic radial-piston motor (10) with an adjustable cylinder ring (18) which has integrated means designed to determine the eccentricity (20) between the cylinder ring (18) and the rotor (14). The eccentric position of the cylinder ring (18) leads, in conjunction with the rotating rotor (14) and the restraining of the guide shoes (17) on the cylinder ring (18), to a stroke action of the piston (16) in the radial direction. This, and kinematic conditions in the motor (10), leads to a change in the distance between two consecutive guide shoes (17). This change in distance takes place in proportion to the eccentricity (20) of the cylinder ring (18) and is determined by a measuring device. This measuring device has a signal transducer (27) which generates an amplified voltage signal as the guide shoes, which act as signal generators, move over it. This signal is fed to evaluation electronics (28) where it is used to determine the eccentricity, rotor rpm and other parameters.

Abstract: A pump or compressor includes a rotating shaft, and at least a first piston rod substantially perpendicular to the rotating shaft and connecting a first pair of pistons at opposite ends of the piston rod. The piston rod moves back and forth relative to the rotating shaft. The compressor additionally includes a circular eccentric, and a circular ring connected to the circular eccentric via a bearing. A drive pin engages the circular ring at a fixed position on the circular ring and engages the at least a first piston rod. When rotational motion of the shaft rotates either the first piston rod and first pair of pistons or the circular eccentric, the drive pin and the first piston rod move back and forth relative to the rotating shaft.

Abstract: A hydrostatic radial piston machine 10 is proposed, whose adjustable reciprocating ring 18 has integrated means for detecting the eccentricity 20 between the reciprocating ring 18 and the rotor 14. In combination with the rotating rotor 14 and the binding of the sliding blocks 17 to this reciprocating ring 18, the eccentric location of the reciprocating ring 18 leads to a reciprocating motion of the work pistons 16 in a radial direction. Together with the kinematic conditions in the radial piston machine 10, this leads to a change in the spacing between two successive sliding blocks 17. This change in spacing varies in proportion to the eccentricity 20 of the reciprocating ring 18 and is therefore detected by a measuring instrument. To that end, this measuring instrument has a measured value pickup 27, which is integrated in the reciprocating ring 18 and outputs an increased voltage signal as long as sliding blocks 17, which act as measured value transducers, move past it. The signal course is delivered to an electronic evaluation unit 28 and used by it to determine eccentricity, rotor rpm, and other characteristic variables.

Abstract: Two adjustable-stroke pumps are driven off a common drive shaft and supply fluid to respective consumers via respective control valves settable by the user of the system. Each pump is provided with its own pressure regulator operative for regulating the output pressure of the respective pump by automatically adjusting the setting of the stroke-adjustment member of the pump. Transducers generate first signals indicative of the settings of the stroke adjustment members and second signals indicative of the settings of the control valves. A control arrangement maintains the settings of the volume-adjustment members in correspondence with the settings of the control valves by automatically altering the operation of the pressure regulators in response to discrepancies between the settings indicated by the first and second signals. An anti-overload arrangement responds to overloading of the common drive machine for the pumps by altering the operation of the regulators in a way decreasing the stroke of one or both pumps. However, even during the anti-overload stroke decrease, the relative settings of the plurality of stroke-adjustment members are maintained in correspondence with the relative settings of the plurality of control valves.

Abstract: A flow control system for controlling a variable displacement pump including a metering valve in fluid communication with the pump for metering an output of the pump. A regulating valve receives a portion of the output of the pump as a bypass flow at a first pressure, wherein an output of the regulating valve is at an interim pressure. The interim pressure is substantially equal to an average of the first pressure and a low reference pressure. An actuator sets a displacement of the pump by acting on a piston connected to a cam ring of the pump. The actuator receives the interim pressure and, thereby, the output of the variable displacement pump is determined.
