Individual pressure compensator
2-way which ensures for load sensing systems based on several different loads connected in parallel that the load sensing pressure difference remains constant at the metering orifice regardless of the
Displacement volume
motor displacement Of a hydraulic pump output volume or flow rate Of a cylinder Geometric volume based on piston area and piston stroke. With differential pistons, the volume at the rear would have to
Contact pressure gauge
Standard pressure gauge with a spring-based elastic measuring element which features a spring contact in addition to the pointer with its electrical limit value indicators to ensure there is an upper and
Program module
structure. A control : Consequence associated with control instructions for a self-contained application-based function (as per DIN 19 237).
Nominal operating conditions
Conditions for which a device has been designed based on its application. The details — if not already specified in standards — are generally set out in manufacturer's catalogues and identified via the
Rapeseed oil
Biologically degradable, i.e. environmentally-friendly hydraulic fluid. based on natural base oils. Besides the desired environmentally-friendly properties, rapeseed oil displays properties such as poor
Flow sensor with oval rotor assembly
Volume counter (not a flow rate counter !) based on two oval rotors with special teeth which cause the fluid flow to rotate ( Figure O 12 ). The flow sensor with oval rotor assembly operates with great
Differential pressure gauge
pressures. This can be a pressure gauge with display or an electrical output. It can also be a device based on a or a piezoresistive system that either indicates the measured variable or further processes it
Nominal pressure
value as per DIN 40 200. The values specified for a device operating under nominal conditions are based on this.
Labyrinth gap seal
Seal type for sealing rotating areas based on a gap seal whereby the pressure energy is dissipated when a suitable surface is formed in the interplay between vortex formation and flow resistance ( Figure
