WebModern hydraulic pumps (axial-piston, radial, vane, etc) are designed with internal leakage passages for cooling. Somewhere between 2-6% of total flow is "leaked" or intentionally siphoned away from the flow outlet for cooling of the pump's sliding surfaces. The flow rate through these passages is obviously dependent on viscosity. WebAlong with the shuttle valves, another critical piece in every Load Sense system is the pressure compensated flow control valves (also known as pressure compensator valves) in the valve section.
