摘要：
This invention relates to a piston pump in a brake system having a piston, which is drivable in a reciprocating motion in a cylinder by an eccentric tang. To avert damage to a ring seal, a support ring is provided which keeps the ring seal spaced apart from a guide sheath for the piston in the cylinder by a distance that is at least as long as a stroke length of the piston. This prevents running scratches on the piston from coming into contact with the ring seal.
