Proportion of the time Tb for which a system or device (e.g. pump) is in operation during a specific period of time T s (e.g. a month or year). The duty ratio, besides what is required by way of reliability [...] level required for devices (e.g. the lower the duty ratio, the less important the efficiency of a pump will be).

motor with constant displacement . Its variable rotation speed is determined solely by the (variable) pump or an upstream flow valve.

On hydrostatic transmissions the transmission efficiency comprises the total efficiency of the pump and motor: From here the total power loss is obtained:

The speed ratio of a hydrostatic transmission is defined by the ratio of the pump speed n 1 to the motor speed n 2:

Flow rate that a pump delivers. The term delivery flow should as far as possible no longer be used in fluid technology, instead flow rate should be used.

Actuation of the adjustment equipment in a pump/ motor by an electric motor. Permits in general adjustment speeds that are not very high. Mostly slower than electro-hydraulic adjustment.

Basic design for a hydraulic drive in which the pump draws in the hydraulic fluid from a storage tank, the surface of which is open to atmospheric pressure. The oil is conveyed to the consumer via directional [...] work is performed, is fed back to the tank. It is not possible to reverse the direction in terms of pump delivery. Excessive negative pressure in the suction line should be avoided. A reversal of direction

Filter that is built into the high-pressure line, i.e. after the pump. It is an advantage that only the pump delivery flow must pass through it and that the following components are protected (Figure D

c transmission , the pump can be adjusted and the motor is associated with constant displacement . The drive rotation speed is therefore proportional to the flow rate for the pump, i.e. the adjusted d

classification characteristic based on drive kinematics for axial piston swashplate (axial piston) pump or motors whereby torque is transmitted to the cylinder drum via the pistons.
