ABSTRACT:
A pumped medium supplied to a suction chamber of the pump is first introduced under the action of the plunger into a working chamber of the plunger and then into a pressure chamber and a subsequent pressure line. The seats of a suction valve and of a discharge valve are arranged on a housing of a central valve, which can be inserted into a cylinder head through an opening formed in a cylinder head which can be closed by means of a base part. A piston-like element which is provided with intermediate seals between the base part and the central valve housing serves to secure the position of the central valve housing. The piston-like element is acted on at both its end faces, due to the provision of spacing chambers, by the pressure of the pumped medium in the pressure chamber. The seals are wedge-shaped so that they are increasingly urged radially outwardly against the cylinder head under axial loading.
