Charge pump

The flow rate Q of a hydraulic motor s calculated from the volume per revolution Vg, the rotary speed of the motor n and the volumetric efficiency factor ηv of the motor. Calculate the pump-flow of a

Controller concepts

As the tube casing and piston of a cylinder normally have a circular cross-section, the pistons can rotate in the face of tangential forces. Where this is not permitted and is not prevented by the app

Sealing systems in which the two surfaces involved in the sealing process do not touch. Due to the remaining gap, non-contact seals can never seal completely. The most important representatives of non

Multi-circuit pump normally with an inclined axis design, but also a design according to the swash plate principle, in which two drives are included in one housing. In the case of an inclined axis des

In general : Range within which the are spread if the same input signal is repeated ( Figure W 11 ). Measurement technology : Quantitative expression of a random error, which arises if different teste

Pressure required to start or maintain the function of a valve (device). The control pressure can be, but does not necessarily have to be, identical to the pressure in the system. A differentiation is

Special form of vane machines , in which six "vanes" (sealing edges) are placed on the rotor. Sealing between the suction and pressure chamber is performed by four synchronous-running sealing rotors (
