ABSTRACT:
A flow divider and combiner for delivering and receiving fluid under pressure to and from independent motors which are linked together for operation by an external force. The unit includes sliding flow control spools and relief valves operable within an orifice to provide a variable orifice for the control of flow with regard to pressure differentials. Through selection of the relief valve shapes and structures, the unit can be programmed for differential pressures existing between the inlet or outlet portions of the device and the differential pressures associated with the chambers connected to the independent motors versus the flow volume to the motors. This structure provides for a high degree of control at relatively low pressures and volume flow where such control is critical to proper operation and allows for less control and pressure loss at higher speed where such control is less critical to proper operation.
