Interaction of one or more pumps (primary element) with one or more (secondary element, in most cases a hydraulic motor). The distance between the two devices is of no significance (open transmission)

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

This term covers all combinations of electrical (electronic) signal processing with hydraulic drives. These combinations can be divided into three groups: Electro-hydraulic technology in which hydraul

As hydraulic systems have low inherent damping, additional measures must be taken to shorten the transient response. This is achieved by: Measures to convert energy, i.e. by throttling, friction or in

Describing function is the term used on non-linear transfer elements for the frequency response while only taking into account the fundamental oscillation of the , recorded or calculated for various c

On the usage of a flow control valve the actuator will jump slightly on switching on the flow rate before the flow rate set becomes effective. This movement is termed startup discontinuity. It is caus

Range within which the disturbance variable can lie, without jeopardising the functionality of the control or (DIN 19 226).

The flow coefficient α is a proportionality factor for the calculation of the flow rate through flow resistances, for example the following applies for orifice-shaped resistances with A = geometricall

Transfer factor

The torque M of a motor is calculated from the pressure p, the volume per revolution Vg and the hydraulic mechanic efficiency factor ηhm of the motor. Calculate the torque output of a hydraullic motor
