Abstract

A conveying device for a vehicle brake system, to convey pressure fluids into at least one vehicle brake, or to convey pressure fluids into a pressure fluid accumulator, or to convey pressure fluids into a master brake cylinder with at least one moveable piston (2) in a receptacle (4) to displace pressure fluids from a working chamber (5′), has at least one non-return valve (9, 9′) to vent the working chamber (5) and to temporarily separate a hydraulic connection between the working chamber (5) and a hydraulic channel, whereby the non-return valve (9) must have at least one valve seat (11) and one valve body (12).To achieve the simplest possible assembly of the non-return valve (9), the valve seat (11) is assembled from several special valve seat segments (13,14).
