    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： Cavitation in axial piston motors (20) caused to act as a pump by an aiding load (28), and the related difficulty of loss of hydrostatic film (52), and tipping or hammering of motor slippers (64), can be reduced by a method which includes the step of recirculating hydraulic fluid from the supply port (18) of the motor (20) to the return port (30) of the motor (20) upon the occurrence of an aiding load (28).

    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.

    摘要翻译： 用于通过柔性管段推动液体的蠕动泵。 泵具有带有多个凸轮的凸轮轴，每个凸轮具有驱动表面。 相邻凸轮的驱动表面相对于凸轮轴彼此成一定角度。 泵还具有多个凸轮从动件，每个凸轮从动件在垂直于凸轮轴的轴线的共同方向上往复运动。 每个凸轮从动件具有骑在凸轮的驱动表面上的凸轮表面和用于接合柔性管段的管接合表面。 凸轮从动件中的至少一个是限制凸轮从动件，其中管接合表面与柔性管段接合比其它凸轮从动件更长的周期。 泵还具有用于使凸轮轴旋转的马达，由此凸轮引起凸轮从动件各自接合并闭塞柔性管段，以在柔性管段中形成传播的凹陷波，用于推动液体。 限制凸轮从动件防止液体反向流动。
