Abstract
In a pressure-regulating arrangement between a pump and a load, in particular between a fuel pump and an internal combustion engine, in which, if the flow from the pump exceeds a predetermined pressure, a cutoff quantity is branched off and fed back into a storage container, according to the invention the pressure regulator (9), together with the cutoff line (14), is combined with a filter (2) in one structural unit. All three connections (feed (4), flow (7) and cutoff connection (15)) are preferably arranged on the same side of a common housing (1). In a particularly advantageous embodiment, all three connections are arranged coaxially with one another, so that if an appropriate connecting piece is used, installation faults can be ruled out.
Claims6
A pressure regulator and fuel filter mechanism for use between a fuel pump and an internal combustion engine in which the mechanism has:
- (a) a housing comprised of a plurality of walls;
- (b) a cylindrical filter and a fuel pressure regulating and by-pass valve structure disposed within the housing;
- and (c) wherein the fuel filter mechanism further includes fuel input, output and by-pass connections extending through the same housing wall to provide commonly located fuel input, output and by-pass openings into and from the interior of the fuel filter mechanism.
