Method for installing hydraulic valves, in which individual function blocks are stacked on one another like a tower ( Figure T 20 ). In this way, valves can be fitted on three or four free surfaces.

The force required to actuate a valve . The control force reaches its maximum value at the full input signal and is zero with zero input signal. Here there is a device-specific dependency for the outp

Hydraulic pump , consisting of several single pumps working in series. The aim is to achieve a higher pressure than permitted by the single pump. Sample application: Internal gear pump , which reaches

Adaptation of controller properties to the respective task by changing the control parameters with the aim of optimising the controller .

Specific type of seal, e.g. roof-shaped seal , u-shaped seal.

Design element that on piston pumps supports the piston at the sliding surface (swash plate, raceway). To reduce the contact force and therefore the friction the slipper is designed such that it can a

Statement on the response sensitivity of components and machines to electrical, i.e. predominantly electromagnetic fields. It is a physical occurrence that may need to be addressed by means of suitabl

Elastomer seal that is designed and installed such that it seals the damping piston as it moves in, and at the same time leaves open a precisely defined gap through which the displaced air escapes (Fi

Contamination of the hydraulic fluid in a hydraulic system prior to the first flushing. It comprises the contamination that is in the hydraulic fluid itself prior to filling the hydraulic system and t

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
