Hydraulic pilot stage in continuously adjustable valves for converting the mechanical output signal from the electrical input stage into an amplified hydraulic signal (Figure D 87) . Armature and flap

Valve which is open when at rest and is closed by actuation for the flow rate. Opposite: Normally closed (NC) valve .

Measures for the automatic adjustment of the controller parameters . The majority of operations that are necessary for the re-optimisation of can be defined in schemas and described by formula-based r

The elements in hydrostatic displacement machines , which bring about the suction and transport process. They include, for example, the teeth in geared machines, the vanes in vane machines or the pist

Combination of two filters with a control unit so that the entire flow rate can be passed through one of the two filters while the other can be cleaned. (Figure D 32)

Throttle with a constant cross section. Opposite: variable throttle .

Operating pressure

To reduce the activation time of a DC solenoid its coil is placed upstream of an Ohmic resistance R v and increased voltage is applied. This reduces the activation time. As the solenoid voltage falls

Circular ring with an almost perfectly round cross section which is mainly used in fluids technology to seal machine parts when at rest ( Figure O 11 ). Its sealing action is achieved through axial or

Characteristic whereby every genuine fluid reduces in volume under pressure. The compressibility associated with mineral oil is also dependent on the temperature and the kind of change of state involv
