    Abstract: 一种静压径向活塞式机械10,一整合在其活塞环18上的装置被用来测量该活塞环18与转子14之间的偏心度20。活塞环18的偏心位置,旋转的转子14,以及该滑座17铰接于该活塞环18上,导致工作活塞16沿径向方向的往复运动。该往复运动和该径向活塞式机械10的运动关系导致两个相继的滑座17之间的距离发生变化。该距离的变化与该活塞环18的偏心度20成比例并因此被一测量装置测量。该装置具有一整合在该活塞环18内的量值传感器27,当该作为量值发送器的滑座17从其上经过时,该量值传感器27产生一增大的电压信号,该信号过程被输送到一电子测量装置28中,并因此测量出偏心度、转速及其他的参数。

    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.

    Abstract: A motor, such as an internal combustion engine or an electric motor, drives two or more pumps, which pump fluid through a discharge system, and a speed measuring device is provided for producing a signal when the speed of the motor is reduced due to the load on the motor reaching a predetermined high value, short of an overload. Two or more pump discharge regulators are provided, one for each pump, cooperating with the measuring device to reduce the output of at least one of the pumps in response to a signal to thereby prevent overloading of the engine or motor.

    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.
