Hakuteksti "pumps".

the pivoting angle of the pumps depending on the sum pressure of both pumps such that the maximum power is not exceeded. In this way, although the delivery flows of both pumps are reduced by the same amount [...] Adjustment system for double pumps with an equally high flow rate, whose adjustment devices are mechanically or hydraulically coupled and which transport the flows in two different circuits with different

Expression frequently used for a pressure controller for variable pumps.

rotation speed (large pumps must run slower to still be able to suck up the oil themselves). If larger rotation speeds are required, the oil must be fed under pressure. Supply pumps are used for this, which [...] in open or closed circuits (however, here they can be kept significantly smaller than " flushing pumps ").

measures such as the reduction of the throttling losses by means of the usage of multiple pumps or variable pumps , Energy-saving circuits ( load sensing, closed circuit , motors with secondary regulation) [...] recover energy . Specifically these are the following measures (Table E 2) : Design improvements on pumps and valves by the manufacturer, Selection of designs with better efficiency by the user, Reduction

power will be equal to the total for the corner power . With variable pumps , it is possible to make better use of power from pumps operated simultaneously with the help of a sum power controller or limit

fluid admission in the displacement chambers as fluid drawn is in. Application: vane pumps , valve-less radial piston pumps . Opposite: internal support .

Pump block consisting of several individual pumps with a shared drive shaft. This is achieved by either arranging things axially in a row (where the shaft for the first pump has to transfer all the power) [...] this arrangement, it is possible to have a shaft running right through to accommodate additional pumps.

Collective term for pumps and motors which operate in accordance with the laws of hydrostatics (see also hydrostatic displacement machines).

Size (possibly limit value) of the axial and/or radial load of the shaft of hydraulic pumps or hydraulic motors .

while the necessary vacuum is produced on the suction side. External gear pumps are the simplest and most economical hydraulic pumps and are very suitable for simple low-pressure drives. They operate with [...] are then also so noisy that for pressures above 200 bar they are often replaced with internal gear pumps .
