Abstract (en)
[origin: WO2005038267A1] A selector and direction device for hydraulic components, such as pistons and motors, comprises a selector valve in the form of a double three-port valve (20). A direction valve (10) is connected to the inputs of the selector valve and is also connectable to a source of hydraulic pressure (2), wherein the direction valve determines the direction of flow through the selector valve. The device also comprises an control unit for activation of the selector valve and the direction valve. Activation of the direction valve thereby controls the direction of fluid flow through the component to be controlled and activation of the selector valve controls whether fluid flows to the unit to be controlled. A rational, economic, and flexible system is provided which as far as possible is based on standard valves of a simple and reliable kind which together can be assembled to units of different sizes for the control of an optional number of components.
