Displacement volume
Of a hydraulic 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 rea
Displacement chamber machines
Collective term for hydrostatic displacement machines whereby the displacement units are generally pistons moved in a linear manner such as a pump with banked pistons/in-line piston pump , displacemen
Hydraulic motor
Device for converting hydraulic energy (Q, p) into mechanical energy (M, n) by creating a certain torque and rotation speed. Neither is dependent on the other: the rotation speed n 2 is only dependent
Fluid mechanics
Concerned with the physical characteristics and behaviour of fluids at rest (hydrostatics) and when moving (hydrokinetics)
Hydrostatic transmission
Interaction of one or more pumps (primary element) with one or more (secondary element, in most cases a hydraulic motor). The distance between the two devices is of no significance (open transmission)
Hydrokinetics
Branch of hydraulics . Concerned with the rules governing the flow of fluids with low compressibility and little internal friction. In hydrokinetics, the transmission of energy mainly occurs via the k
Hydromechanical efficiency
Losses in hydrostatic input/output elements mainly caused by friction forces — which may depend on rotation speed, pressure or velocity — and by flow losses . The resulting loss torques are M c = cons
Hydraulic piloting stage
Another expression for hydrostatic amplifiers associated with servo valves .
Hydraulic signal technology
Signal range in which the signal input , signal linking and signal output use hydraulic components. Hydraulic signal technology is very expensive and only suitable for a few linking applications given
