Arrangement of things side by side whereby both the inputs and outputs for elements are connected to each other. When hydraulic resistances are arranged in a parallel circuit, the flow rate in the ind

Hydraulic motor with constant displacement . Its variable rotation speed is determined solely by the (variable) pump or an upstream flow valve.

Characterises the transient response of a linear system in the frequency range. It is independent on the type of system excitation, i.e. it is irrelevant whether a system is excited by a periodic or t

Accumulator drive system , which supplies its consumers via two pipeline networks, one with low-pressure and one with high-pressure, in order to save energy. In hydraulic systems, the low-pressure lin

With proportional spool valves, the overlap/underlap at the individual control edges of the valve (overlap/underlap conditions) determine the flow rate signal characteristic curve ( Figure N 6 ) and t

Non-continuous controller with two switching positions. The output signal can only take on 2 different values (neglecting the switching processes). Multi-position controller

Non-contact seals (e.g. gap seals ) are not suitable for gases due to their lower viscosity unless they are combined appropriately with a liquid as a barrier medium ( Figure S 73 ). Depending on the d

Static pressure above the calculated pressure to check a device or system under defined conditions. There must be no long-lasting malformation, damage or incorrect functioning (DIN 24 311).

Mathematical description of a follow up control in which, with the aid of the frequency response method, the transient response is determined (Figure F 36) .
