The invention relates to a pump comprising a pump unit, an intake line, and a valve device associated with same for implementing suction regulation of the pump, and comprising an intake region downstream from the valve device as viewed in the direction of flow of the medium conveyed by the pump.

Pump having a magnetically actuated control valve for suction regulation

The invention relates to a radial piston pump, comprising an inlet chamber with an inlet connection, an eccentric which may be driven in a rotating manner, arranged within the inlet chamber, for driving at least one piston of the radial piston pump, a cylinder bore for guiding the piston and an inlet controller, which opens and closes a connection between the inlet chamber and the cylinder bore, depending on the piston position. The radial piston pump is characterized by at least one balancing element ( ) for the eccentric ( ), which rotates synchronously with the eccentric ( ) in the inlet chamber ( ), the balancing element ( ) being so arranged in the inlet chamber ( ) and/or so formed in its contour that a hydraulic resistance is formed between the inlet connection ( &prime;) and inlet controller ( ), or the flow of medium reaching the inlet controller ( ) is unaffected.

Radial piston pump

The invention relates to a hydraulic delivery device with a displacement unit which delivers a medium from a suction connection under output pressure to a pressure connection, connectable with a consumer, and under consumer pressure, and a regulating device for setting and/or limiting a volume flow delivered by the delivery device.

Flow control valve for a pump for conveying a medium

A flow-regulating arrangement for a hydraulic transport device such as a vane-cell pump includes partial-transport flow throttles which operate independently of one another and which are arranged in parallel to deliver output of the hydraulic transporting device to a hydraulic load. One of the partial transport flow throttles responds to the pressure difference between working pressure of the hydraulic transporting device and pressure within a pressure chamber internal to the device.

Flow-regulating arrangement for a hydraulic transporting device

A hydraulic pump with a falling characteristic curve in respect of the output flow relative to the pump speed. A flow control valve (40) has a spool (41) with a hollow (50) extension portion (49), and an annular chamber (52) with two control edges (53, 56) which co-operate with the valve output duct (38) and a relief duct (19) to form restrictor means which are in opposition to each other. The valve output duct (38) and the relief duct (19) are disposed substantially radially with respect to the spool.
