Pilot control behaviour
Provides information on the behaviour of the controlled variable with a changing reference variable , but constant disturbance variable . The controlled variable responds to external effects on the co
Short stroke cylinder
Cylinders whose stroke is significantly shorter than the piston diameter ( Figure K 41 ). Short stroke cylinders are used in hydraulics for things like tensioning or closing processes.
Pump drive
Drive system, in which the flow rate for all movements is provided directly from pumps (without a storage facility). If different speeds are required, constant pumps are used in throttle control and v
Load-holding valve
In accordance with ISO 1219-1 load-holding valves are classed in the group of pressure control valves. They prevent double-acting consumers (such as hydraulic cylinders and hydraulic motors) that have
Pre-fill valve
Piloted check valve that is used to fill the cylinder chamber behind a piston moving rapidly under its own weight or with a piston for rapid traverse with unpressurised oil from the tank. The high vel
Screw-in throttle
Throttle valve that is designed as a screw-in cartridge.
Design pressure
Pressure that is defined by the person planning a device or installation to fulfil the intended functions. It corresponds to the nominal basis according to DIN 40 200 (DIN 24 312).
Arithmetic mean, average
The arithmetic mean or the average of a series of measurements with n independent individual values x, 1 ... x n, termed x̄ for short, is defined by (VDI-VDE 2600).
Analogue technology
Collective term for all electronic signal processing and switching technology that has analogue behaviour with the characteristic that the output variable changes corresponding to the change in the in
