The flow rate in a hydraulic system with a variable pump and appropriate adjustment corresponds to the requirements in accordance with which the adjustment functions. The term impressed, i.e. pre-defi

Memory location number for the unambiguous identification of a memory location. The number of elements from a finite quantity of words for the identification of storage cells (memory locations) in con

Pressure for which devices or systems are calculated under defined conditions to obtain functionality (see also DIN 2401, Part 1). The calculated pressure can be definitive for the operating pressure

Measurement of signals at regular intervals, e.g. controlled variables.

Determination of the ongoing position change of a functional element on an axis (e.g. the piston of a cylinder or valve ) and feedback for processing in a closed circuit position control system . The

Continuously adjustable valve is the collective term for valves such as proportional valves , high response proportional valves and servo valves, which can be continuously adjusted .

Variable pump that pans from +max, though zero, to –max flow rate . Thus the suction line becomes the pressure line and vice versa without changing the rotating direction ( Figure R 27 ). Reversing pu

Most commonly used form of hydraulic fluid (" oil hydraulics "). Their high level of lubricity and relatively high viscosity make it possible to use gap seals in pumps and valves and therefore choose

Biggest difference for the same when travelling across the full signal range (i.e. forwards and backwards). Hysteresis values are expressed as a percentage of the max. signal value (Figure H 31) . Wit

Directional valve that has a 4th switching position in addition to the three standard positions. The 4th position can be used to solve particular tasks, such as a fail safe position in the case of a f
