The total efficiency of a hydraulic device or system is always given by the product of the volumetric and the hydromechanical efficiency (Figure G 7) :

Cylinder , in which two or more separately pressurised pistons are arranged one after another, which act on a piston rod such that their forces are added together ( Figure T 3 ). Tandem cylinders are

The Reynolds number is a dimensionless quantity indicator for the ratio of the forces of inertia to the forces of viscosity or friction in flowing Newtonian liquids. It depends on the flow velocity v,

As a synchronizing cylinder (Figure K 5) with oil spring stiffness. The oil spring stiffness for cylinder side A and cylinder side B are arranged in parallel and add up to the total oil spring stiffne

Transfer function of the subsystem with respect to changes to the correcting variable (DIN 19 226).

Design of hydraulic motors with a radial arrangement of pistons . Radial piston motors are predominantly slow speed high torque motors in which several pistons are positioned perpendicular to the driv

Gas pressure that is applied to a fluid vessel with or without separator. On hydraulic accumulators the gas filling pressure corresponds to the precharge pressure. Example: hydropneumatic accumulator

Servo valve

Process to monitor the operating state of a hydraulic system or individual devices with the aid of temperature and pressure measurements . It uses the hydraulic fluid to carry the information and is b

Valve with the task of switching circulating the pump flow rate back to the container without pressure if it is not needed. In order to keep power losses low in doing so, this takes place on the short
