Closed circuit
Basic design for a hydraulic drive in which the fluid circulates from the pump to the actuator and from there straight back into the suction line of the pump. The main difference between this and an "
Collapse pressure
Pressure at which a filter element becomes so crushed (destroyed) that it ceases to function. According to ISO 2941, however, the collapse pressure is simply the pressure at which the filter element i
Rotary piston
Effective element of a limited angle rotary actuator with mostly a rectangular cross-section that is fastened to the shaft and to which a flow of hydraulic fluid is applied.
Adjustment time
Time at which the correcting variable runs through the correcting range at the maximum considered correcting speed (DIN 19 226).
Wheel motor
Hydraulic motor , which can be integrated directly into the wheels of a vehicle. This produces a direct transfer of the force without interposing a manual transition, cardan shaft and differential gea
Law of superposition
The law of superposition states: If an input variable (xe1) brings about an output variable (xa1) and also another input variable (xe2) brings about an output variable (xa2), therefore: if the law of
Temperature range
Area between the minimum and the maximum permitted temperature (e.g. of the medium, environment, etc.)
Clock signal
Signal supplied to the accumulating functional elements of a synchronous control via their clock. At signal value "L": Clock pulse and at signal value "0": Clock pause (DIN 19 237).
Control volume for valves
Geometric volume required for the actuation element of a device to function.
