Abstract

A fluid motor (97) is set into the return flow of a hydraulic or pneuma-machinery. This fluid motor (97) has a relatively large consumption capacity to revolve at low speed, but it can be a low pressure motor. The motor (97) is utilized to revolve or oscilate one or more control devices which may be used to control the operation of the machinery with the return flow whereinto the fluid motor (97) is set. Specific additional matters are then proposed to secure the smoothly timed and reliable operation of the fluid motor and of the controller(s) which it drives.
This control arrangement with the fluid motor (97) in the return flow fluid line may be utilized to control the operation of a high pressure pump. This pump may have medial pressure (8, 9) and high pressure (5, 6) pistons, reciprocating in respective cylinders, as well as inner- and outer- chambers with deflectible separators (58) between these chambers in order that the outer chamber may contain a lubricatious fluid while the inner chamber can then contain a non-lubricative fluid, as for example, water.
The fluid motor (97) in the return fluid line may be replaced by another motor, for example, an electric motor with a reduction gear, to enforce a low speed operation of the control device(s). If the apparatus of the invention is a complete use of all details of the invention, a pump can provide a flow of water with pressures in excess of 30 000 psi.
