Abstract: The present invention relates to a rotary fuel pump (101). The pump (101) has a rotor (107) and at least one pumping element (115) for supplying high pressure fuel. A cam box (123) containing a cam arrangement (103) is provided for actuating the at least one pumping element (115). A speed dependent fuel pressure line (129) is provided for supplying speed dependent fuel pressure to an advance arrangement (125) for adjusting the timing of fuel delivery by the pump (101). A first vent line (131) is provided for venting air from the speed dependent fuel pressure line (129). The first vent line (131) is in fluid communication with a collection chamber (137) for collecting air vented from the speed dependent fuel pressure line (129). A second vent line (141) is provided for venting air from the collection chamber (137). The second vent line (141) is a helical groove (141) formed in the rotor (107) or a pump housing (105). The present invention also relates to a rotor (107) for a fuel pump (101).

Abstract: A sensor arrangement and a method for its use for detecting the proximity of a ferrous target, the sensor arrangement comprising a sensor body including a magnetic field source and a Hall effect device, wherein the magnetic field source is an electromagnetic solenoid. The invention has particularly utility, but is not so limited, to the field of fuel injection pumps in which it is necessary to determine the volume of fuel that is delivered to the cylinders of the engine without affecting the operation of the engine.
