Special form of internal gear pump , in which no sealing sickle is required, as the seal between the fixed gear ring and the rotor (planetary gear) is directly possible through the suitable design of

Program

Collective term for seals with a round or almost round cross section. The most important is the O-ring. Another is the Quad-ring along with others within this group ( Figure R 40 ).

Measuring arrangement, in which a sensor is integrated in a device with a standard electrical with zero and end point comparison elements, which can be adjusted externally and issues a standard output

A hydrostatic transmission with secondary adjustment works with an impressed flow ( constant current network ) and has a constant pump and a variable motor, which performs the torque setting itself. T

Slim, cylindrical measuring device for simultaneous recording of static pressure perpendicular to the direction of the flow and total pressure along the direction of the flow. The pitot-static tube is

Amplification in the and therefore the product of the amplification factors (proportional coefficients) associated with the individual elements (, controlled subsystem , measuring device) in the open

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) :

Functional construction of a control consisting of various modules or groups, including their connections.

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,
