    • The proposal is for a liquid filter (10) with an incorporated pressure regulator (11) for fuel in which the pressure regulator (11) with its diaphragm (41) is installed inside a facing component (18) with at least one connection (19) on the housing (12). The disc-shaped diaphragm (41) has a single clamping point (39) at its outer periphery and a central movable closing member (42). Pressure in a pressure chamber (45) coupled to the clean side is applied to the diaphragm (41) against the force of a spring (49) in a gas-filled spring chamber (48). The integration of the pressure regulator (11) into the housing (12) results in a simple, compact and economical design of the liquid filter (10), in which only purified fuel flows through the valve (44) in the pressure regulator (11) and which is insensitive to back-pressure in the tank connection (17).

    • In prior art pressure control valves the valve closing body is secured to the diaphragm; this not only increases production costs but also means that the mass to be moved is great, thus reducing the rate of reaction to pressure changes. In the novel pressure control valve, the mass to be moved on the diaphragm (40) is reduced by fitting a valve seat body (43) with a valve seat surface (44) in the central region of the diaphragm (40) so that when the valve seat surface (44) is lifted from the valve closing body (30), fuel to be controlled can flow from the pressure control side (45) of the diaphragm (40) to the return flow side (47) of the diaphragm (40) via the valve seat surface (44) and a return flow channel (54). The pressure control valve is particularly suitable for use in fuel supply systems in internal combustion engines.
