Stroking of hydrostatic machines

Where flow resistors ( orifice , throttle ) are used to control the movement of hydraulic motors and cylinders ( control with throttle ), this is based on the principle of connecting pressure dividers

The valve control spools on three way valves are, with the exception of very large nominal diameters, placed in the centre position and maintained there by two springs as soon as the solenoid force or

Devices that close or open electrical contacts in the event of pressure load (DIN ISO 1219-1). They are generally used if an electrical switching command or status signal should be issued when a set (

Flow resistor () with laminar flow, e.g. capillary gap. Has a largely linear flow rate pressure characteristic .

Metal block, which houses several valves through incorporation or addition. The connections necessary for it to function are drilled into the block and are connected to the corresponding lines.

Torque amplifiers

Factors (boundary conditions) that affect the operational sequence and the function of systems and devices. These include the load curve, behaviour, installation conditions, operating conditions etc.

In hydraulic systems, locking is required primarily for safety aspects (aircraft landing gear, lifting platforms, etc). Additional equipment is also used, such as locking units ( Figure V 15 a ) or cl

Graphic representation of a curve showing all the variables which influence the power delivered by a hydrostatic transmission (e.g. torque, efficiency, slip) in relation to another variable (e.g. rota
