Hydraulic Pilot-Operated Check Valve

The pilot-operated check valve is shown in Fig. 7.11. For flow in the forward direction, this valve operates just like a normal check valve. Pilot line pressure holds the valve open for fluid in the reverse direction. If the pilot … Continue reading

Gear-Type Hydraulic Flow Divider

The gear-type flow divider functions like two gear motors with their shafts rigidly attached. We will consider first the case in which both motors have the same displacement. Since their shafts are attached, they both have to turn at the … Continue reading

Orifice-Type Hydraulic Flow Divider

Theoretically, the orifice on both sides of the flow divider can be adjusted so that the ?P across the orifice plus the load ?P is equal on both sides. Then, the flow from the pump will divide equally, and both … Continue reading
