The invention relates to a pump seal (60) of a piston pump (56) for a vehicle braking system, in which system a piston (58) can be pushed out of a pressure compartment (34) of a cylinder (12) during an intake phase of the piston pump (56) and the piston (58) can be pushed into the pressure compartment (34) during a pressure phase of the piston pump (56). During the pressure phase, the pump seal allows a gap (68) between the piston (58) and the cylinder (12) to be closed in a fluid-tight manner and said gap (68) between the piston (58) and the cylinder (12) to be opened in order to admit brake fluid into the pressure compartment (34).
