Fabric group for seals that comprise textile fabrics that have been impregnated with elastomer components. The seals manufactured from this material are suitable for very high pressures due to their h

On hydrostatic transmissions the transmission efficiency comprises the total efficiency of the pump and motor: From here the total power loss is obtained:

Entirety of all deviations on the actual surface from the geometrically ideal surface. On viewing the surface, a differentiation is made between coarser and finer deviations. For exact differentiation

The technical processes in hydraulics are essentially based on the following basic laws of physics: Pascal's law : (Blaise Pascal, 1623—1662). Every force acting on a stationary fluid generates a pres

Defines the degree to which the velocity x at the zero point (y = 0) increases as a function of the deflection of the control element y, if the load is zero (Figure G 12) .

Measures taken to change the velocity of a cylinder (motor) either by means of information from the circuit (e.g. pressure changes) or by means of information from the exterior. The velocity control i

that has the task of adjusting the velocity in a system as a controlled variable as accurately as possible to a setpoint . For this purpose the actual velocity can be measured via a velocity transduce

Velocity is a variable derived from the distance or angle. It can be obtained either by direct measurement or by differentiating the position. Differentiation of analogue signals If the position is av
