Pressure compensator
Size 10
Application
A combination of flow rate control and pressure compensation.
The flow rate Q is determined by the throttle cross-sections
P1, R, A and P2, R, B. Either a single or a double flow may be
selected. In many applications, the valve is combined with a
variable-displacement pump. The pressure/flow compensator
keeps the pressure drops through the valve at a constant level
(see Fig. 1 on page 11).
The same function is achieved in constant-displacement
pumps, too, by means of a pressure compensator. Here, Qmax. is
determined by the control springs of the pressure compensator
(see Fig. 2 on page 11).
The pressure p is measured by an external pressure sensor and
transmitted to an electronic pressure compensator as an actual
value. Just as the build-up of pressure in the consumer takes
place and approaches the setpoint value, the valve function is
determined by the pressure compensator. Even in situations
where the pressure is decreasing, the valve can regulate the oil
as necessary via the A-T metering notch.
Pressure compensation can be achieved both by means of
electronics provided by the customer and using a Rexroth
pressure compensator.
