Abstract

A valve arrangement having a main valve and having a pilot valve which is provided for controlling the main valve and which is inserted into a pilot valve receptacle in an insertion direction, wherein, through closure of the pilot valve, a pressure is able to be built up within a pressure chamber which is closed off by a diaphragm, whereby a valve seat between a main valve inlet and a main valve outlet is able to be closed off. By opening the pilot valve, it is possible to set a release of pressure within the pressure chamber by water flowing away via an inflow, connected to the pressure chamber, of the pilot valve receptacle and via a pilot valve inlet, adjoining the latter and formed by a main body of the pilot valve. A pilot valve outlet, formed by the main body, and via an outflow, adjoining said pilot valve outlet, into the main valve outlet, opens into the main valve outlet on the outflow side of the diaphragm. The pilot valve inlet and the pilot valve outlet are arranged offset from one another along a longitudinal axis of the pilot valve.
