Special pressure switch valve with the task of switching the constant pump, which charges a hydraulic accumulator , to pressure-free circulation as soon as it reaches its charging pressure and to swit

Valve that can shut-off the flow in both directions. In fluid technology this valve is implemented in the form of a seated valve or ball valve . The valve is actuated manually, magnetically or using a

Frequency with which a system left to itself oscillates after an external excitation ( damped natural oscillation ). For a 2nd order oscillatory delay element (e.g. spring-mass system, hydraulically f

Test dust for undertaking the multipass test according to ISO 4572. The quantities of the individual particle sizes are defined. In this way a consistent contamination basis for all multipass tests is

Disc-shaped or spherical functional element in axial piston machines , which has the task of reversing the rotating piston chambers from suction chambers to pressure chambers and vice versa ( Figure S

Another expression for hydrostatic amplifiers associated with servo valves .

Unit in a computer system that permits operators to monitor and influence the operation of the computer system or its parts. Examples for such actions are bootstrapping programs , monitoring devices,

Control in which the signal states of the input signals are allocated defined signal states of the within the meaning of Boolean connections ( Figure V 12 ). Previously common names, such as parallel

Value which a variable should have at the time under consideration and under the specified conditions (DIN 19 226). In electro-hydraulic control technology, this value is always an electrical variable

To reduce the leakage losses, the ring gear of an internal gear pump is pressed against the internal gear and a sickle-shaped body is placed between the ring gear and internal gear, minimising the pla
