Mechanical connection between the moving parts of a fluid power control device and the moving part of the device to be controlled for the purpose of . Example: Two stage servo valve with flapper-nozzl

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

In fluid technology electro-mechanical used to actuate valves are often referred to as solenoids. These are not permanent magnets, but are electromagnets. An electrical input signal (voltage or curren

Dynamic stabilisation method for oscillations based on the removal of energy by throttling, leakage (bypass) or also friction with the special feature that it can only be activated if oscillations occ

Distance that is required to form from a turbulent a laminar flow and vice versa. The formation of a laminar flow requires a significantly greater distance.

Control whose program is specified by the type of functional elements and their connections (DIN 19 237). With hard-wired controls, application-specific logical connections are made by individual pipe

Symbolic representation of functional interactions between the signals of a system or a number of interacting systems. The functional dependence of the output signals on the input signals is shown as

Valve that switches the pump to a pressure-free circulation as soon as its flow rate is no longer needed in the circuit. Special 2/2 directional valves or pressure valves are suitable for use as a shu

Of a characteristic curve : A curve ( characteristic curve ), whose course deviates continuously or intermittently from a straight, line is approached by straight line at a certain operating point. Su

Describes the flow rate through laminar flow resistors ( capillary tube , gap). It is assumed, based on a steady-state laminar flow and a constant cross section flow, that the compressive force will b
