PISTON PUMP FOR A MOTOR VEHICLE BRAKING SYSTEM, COMPRISING A PISTON ROD

摘要

The invention relates to a piston pump (10) for a motor vehicle braking system, comprising a housing section (12) and a piston (26) that is displacably guided into the housing section (12), and receiving means (20) for receiving an inlet valve (22), a sealing element (18) that is connected to the receiving means (20) for sealing the piston (26) counter to the housing section (12) and a piston rod (62) that is joined to the sealing element (18). Said piston rod (62) has two parts having a first (28) and a second piston rod element (30). In the first piston rod element (28), a fluid inlet (64) for introducing the fluid into the inside of the piston (26) is provided, and the second piston rod element (30) partially covers the fluid inlet (64) in the axial direction of the piston (26).
