Oscillations that occur due to the pressure alteration in the pump from the suction phase to the pressure phase. Their fundamental frequency depends on the number of displacement units in the pump, wh

Periodic pressure surge in a hydraulic fluid that is caused by the constant changing of the individual displacement units in a hydraulic pump from the suction phase to the pressure phase and vice-vers

Variant of a central hydraulic oil supply in which the pressure in the manifold is only applied by variable pumps that are equipped with pressure controllers. The size necessary for the pumps is based

Pressure-reducing valve

Valve that keeps the (lower) outlet pressure (secondary pressure) p 2 constant even with changing inlet pressure (primary pressure) p 1 . This action is achieved by a valve cone, held open by a spring

General : Depending on the nature of the changes in the pressure, a differentiation is made between static and dynamic pressure measuring procedures. Static pressure measuring procedures are when cons

Pressure transducers

Generic term in fluid technology for hydraulic fluids ( hydraulics ).

Expression frequently used for a pressure controller for variable pumps.

Brief pressure rise and pressure drop or vice versa (DIN 24 312).
