Abstract: A fluid flow regulating valve wherein the housing receives a reciprocable spool and has a chamber which can receive pressurized fluid from a pump by way of a pilot valve to thereby move the spool from a neutral position to an intermediate position and thereupon to one of several operative positions. The fluid pressure in the chamber acts against one end face of a piston which is mounted in the body of the pilot valve and can be displaced by a control spring which can be deformed by a manually operated handle. A relatively minor deformation of the control spring suffices to move the spool to the intermediate position so that the spring can undergo a much larger additional deformation in order to move the spool to a selected operative position. A regulating spring in the housing of the regulating valve does not oppose the movement of the spool to intermediate position but the regulating spring offers a substantial resistance to movement of the spool to an operative position. This enables the operator to sense that the control spring offers a greatly increased resistance to further deformation by the handle.

Abstract: First and second control units, having first and second control valves, are provided for connecting first and second pumps with a plurality of hydraulic first and second consumer motors, respectively. The units also include first and second switching valves which can be operated to supply pressure fluid from the respective first or second pumps to the second and first consumer motors, respectively, so that each consumer motor can be also operated with pressure fluid from both pumps.
