Abstract

The present invention concerns a valve arrangement comprising an outlet valve (2), an inlet valve (3) and a valve support (4) with a passageway, the outlet valve (2) being arranged on the valve support (4). According to the invention, the outlet valve (2) comprises a first diaphragm spring (20).

Description

technical field [0001] The invention relates to a valve assembly which may be used, for example, in a fuel pump for a vehicle, and to a fuel pump comprising such a valve assembly. Background technique [0002] Such a valve assembly or such a fuel pump is known, for example, from GB 2478876B. Here, the fuel pump in the form of an electromagnetic piston pump comprises a valve assembly with an inlet valve, an outlet valve and a valve carrier with a through-opening, wherein the outlet valve is arranged on the valve carrier. Furthermore, the outlet valve is designed as a ball valve with a reset element and is correspondingly assembled from several components. This leads, on the one hand, to the valve assembly taking up a large installation space and, on the other hand, to an increased possibility of errors, for example during installation of the valve assembly into the fuel pump. This results in enormous construction, installation and maintenance costs. Contents of the invent...
