Pressure created by flow resistances which must be overcome when feeding back the pressure fluid (to the tank).

Function group consisting of several switching or control elements grouped together on an assembly unit (e.g. control block ).

Term for — mainly slow-speed — hydraulic motors with very high displacement and therefore very high torque. High torque motors are generally designed as multi-stroke hydrostatic motors in terms of the

Most important group of pressure gauges on which the measuring organ deforms elastically and proportionally to the pressure. This deformation is therefore a direct measure of the magnitude of the pres

that has the task of adjusting the pressure in a system as a controlled variable as accurately as possible to a setpoint (Figure D 70) .

Velocity is a variable derived from the distance or angle. It can be obtained either by direct measurement or by differentiating the position. Differentiation of analogue signals If the position is av

This is a 2/2- Directional valve that is designed for installation in a control block . If came about as a result of efforts to simplify controls by breaking down the functions of conventional directi

Hydraulic circuit that is predominantly used in mobile hydraulics . Here the directional valves are closed in the centre position; the flow rate is either routed Via an idle circulation valve (on cons

Measuring instrument that acquires at its input the measured variable "pressure" and outputs a corresponding electrical signal on its output. The pressure transducer therefore comprises a housing with

in which only one physical variable (e.g. distance or pressure or speed), the controlled variable , is fed back (Figure E 8) .
