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

Pump with two or more gear wheels with teeth on the outside that rotate engaged in each other. As a result the hydraulic fluid is pressed out of the gaps between the teeth on the outlet side, while the

Variable pump which is adjusted by an electro-hydraulic closed circuit position control system according to the requirements of a parent control system such that it always moves an exactly defined flow

The gear pump is a machine for conveying fluids in accordance with the Positive displacement principle . In principle it consists of three components: a housing with inlet and outlet and two gear wheels

Pump with two gear wheels in most cases whose outer (ring gear) has teeth on the inside. The inner sprocket is smaller. The fluid is conveyed in the spaces between the gaps in the teeth of the two gear [...] sprocket and ring gear (Figure I 11) . Their geometric displacement cannot be adjusted ( constant pump ). External gear pumps are also well suited for low-pressure drives and are an inexpensive alternative

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)

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

Construction design of an axial piston pump , in which the swash plate and the control disc are firmly connected to the drive shaft and rotate with it, while the cylinder block, which is firmly connected
