Abstract

The invention provides a pump including a pressure valve which is formed within a carrier element capable of being inserted into the pump casing, with the carrier body including a channel leading into a chamber which, in turn, is in communication, through a restrictor, with the brake circuit to be energized. The carrier element, substantially, is of a cylindrical configuration, with the channel leading to the side wall of the cylinder, and the carrier element, in part, being inserted into a cup-shaped retaining element, and with the outer diameter of the carrier element being only slightly smaller than the inside diameter of the closure member.
