Abstract
A liquid filter (,) with a built-in pressure regulator (,) for fuel is proposed, in which the pressure regulator (,) with its diaphragm (,) is mounted on the inside of a cap (,) that has the inflow connector (,) and the tank connector (,). The diaphragm (,), which experiences a flow on its inside, is acted upon by the pressure of the fuel on the clean side (,) of the filter element (,), and the flow through the filter element is radially from the outside inward. Integrating the pressure regulator (,) in the cap enables a simple, compact, economical design of the liquid filter (,), through whose valve (,) in the pressure regulator (,) only cleaned fuel flows.
