摘要： An arrangement for regulating fluid conditioning stations including a plurality of pumping devices, at least one fluid storage reservoir, at least one pressure transducer and regulating mechanism, the conditioning station providing a fluid at a certain pressure and flow for consumption. The pumping devices start and stop such that the pressure in the fluid storage reservoir or reservoirs is maintained between two limit values of pressure (the start pressure and the stop pressure). Only one pumping device is started when the pressure in the storage reservoir(s) reaches or exceeds the value of the start pressure or when the flow provided by the pumping devices in operation is less than the consumption flow. Only one pumping device is stopped when the pressure in the storage reservoir(s) reaches the value of the stop pressure or when the flow provided by the pumping devices in operation is greater than the consumption flow.

摘要： 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.

摘要： A rotary hydraulic machine which includes a housing having a shaft mounted for rotation within the housing about a shaft axis. A cylidner block is coupled to the shaft for co-rotation with the shaft within the housing and includes a plurality of cylinders disposed in a circumferential array parallel to and surrounding the shaft axis. A piston is disposed to reciprocate within each of the cylinders and is coupled to a yoke for determining displacement of the pistons within the cylinders. A valve plate is mounted on a valve block and includes kidney-shaped slots for registering with the cylinders as the cylinder block rotates, and thereby connecting the cylinders to pump input and output ports. A microprocessor-based controller is externally mounted on the pump valve block and includes internal memory having various remotely-selectable control programs prestored therein. Sensors responsive to pump operating conditions are connected to the pump control electronics, and include a first sensor responsive to yoke position, a pressure sensor responsive to pump output pressure and a speed sensor responsive to angular velocity of shaft rotation. All of the electronic components are mounted on the valve block.

摘要： A controlling device ensures an accurate control of the rotational speed of an engine. When a hydraulic working machine is in a suspended state, the rotational speed of the engine can be changed from a designated rotational speed to a low rotational speed without requiring any specific manipulation by the operator. When all control levers 14 to 21 are shifted to their respective neutral positions to suspend the operation, and the shifting speed of the control lever which is lastly shifted to its neutral position is low, a delay time is set to be longer than in the case of high shifting speed. If the control levers 14 to 21 are maintained in their respective neutral positions after the elapse of the delay time, the engine 1 is changed to the low rotational speed mode. When one of control levers is shifted before the elapse of the delay time, the engine 1 is continuously maintained in the designated rotational speed mode.

摘要： A load sensing control system for a hydraulic machine sets a variable target differential pressure between a delivery pump pressure and a load pressure of an actuator. A control factor is determined that becomes larger as the deviation between the target differential pressure and the actual differential pressure is increased, and that becomes smaller as the differential pressure deviation is decreased. The control factor also becomes larger as the target differential pressure becomes smaller. The target displacement volume for the hydraulic pump is based on the differential pressure deviation, which is calculated from the target differential pressure and the control factor.
