Are characterised by the largest and smallest values for the individual variables with which the system is allowed to be operated with other influencing variables exactly defined and with the load dur

Hydraulic bridge rectifier

Gap that is necessary to move a sliding element past a stationary element. In hydraulics the sliding gap plays an important role because on gap seals its magnitude defines to a significant extent the

Constant force characteristic

Is present if there are elements that allocate two value ranges of an input signal in a steady state to two different values of the output signal (two-point elements) (DIN 19 226).

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

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

1. Hydraulic resistance control for a displacement chamber with a type A hydraulic half bridge (adjustable input and output resistance); use of both control edges of a continuously adjustable 3/2-way

Control unit of a machine tool, which only issues an output signal if it is actuated with both hands simultaneously. Two-hand controls are mandatory for manually operated presses.

Check valve with two blockable inflows and one outflow. The inflow with higher pressure is blocked, the other inflow is connected to the outflow. If both connections have the same pressure, both are c
