Abstract
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 ( ′) and inlet controller ( ), or the flow of medium reaching the inlet controller ( ) is unaffected.
