In general : For control elements with a piston design, this states the seal length between the allocated control edges ( Figure U 1 ). in rest position, together with the size of the gap, it determin

On the piston seal of a double acting hydraulic cylinder, in the case of a poorly designed piston seal, pressure fluid can flow from one side of the piston to another in a short time, normally if very

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.

Flow control valve

Throttle valve with adjustable throttle ( measuring throttle , A P), in which the flow remains constant through the combination of the valve with a control throttle (, A R), regardless of the changing

In current-fed systems, the hydraulic motor or cylinder speed or stroke rotation speed is bound by the pump delivery flow . Due to this current feed, a pump can only ever actuate one drive unit. It is

Device, in which the movement of an element (ball, vane, etc.) displays the presence of a flow.

Resistance, which a fluid subject to friction must overcome when flowing through and valves . It is noticeable in the form of a pressure drop ( pressure loss ). The flow resistance comprises frictiona
