the rotary speed of the motor n and the volumetric efficiency factor ηv of the motor. Calculate the pump-flow of a motor directly and easily in our hydraulic calculator .

design, either the toothed drive shaft with one pump as a drive for a second pump ( Figure V 20 ) — in this case both are adjusted using a sum power controller — or a transfer case is used for both pumps [...] Multi-circuit pump normally with an inclined axis design, but also a design according to the swash plate principle, in which two drives are included in one housing. In the case of an inclined axis design

Adjustments of positive displacement machines.

therefore deliver a constant flow rate at a specific rotation speed. When designing an axial piston pump, it is not only the functional principle that comes into play, but also whether the equipment is to

External gear pump with compensation of the radial and axial play to reduce the gaps with increasing pressure . This compensation is achieved by means of suitably shaped and arranged compression springs

in hydrostatic applications for this purpose. A flow rate emerges at the pressure connection of the pump and drives the hydraulic consumers ( Hydraulic motor , Hydraulic cylinder ). These convert the hydraulic

Time that a variable pump requires to adjust from the max. flow rate Q max to a flow rate of zero. In general this time is shorter than the on-stroke time .

causes noticeable pressure losses between the pump and the valve. An integrated pump idle circulation valve which can be connected directly to the pump, ensures a practically pressure-free circulation [...] low-pressure circulation of the pump delivery flow if it is needed elsewhere (excluding turning off the drive motor): The three-way valve has a centre position for pump circulation ( Figure P 38 a ). This

through zero to the maximum negative ( reversing pump ), while for variable motors the range from maximum to zero is sufficient. The advantage of a variable pump is its low power loss, as it only transports [...] transports as much as is required in the respective case ( pump control , primary control ). Variable motors are needed for hydrostatic transmissions with secondary adjustment or primary-secondary adjustment as

Variable pump in position " Delivery flow zero". Often, the pressure hold position of the pump, i.e. the position in which the pump covers the leakage losses incurred, is – incorrectly – labelled the pump's [...] pump's neutral position.
