Abstract: The present invention relates to a connector assembly comprising a connector unit mounted in a housing. The connector unit has a mounting portion, at least one electrical terminal and a body portion having a locking tab. The housing has a first longitudinal axis X1 and the body portion has a second longitudinal axis X2. The first longitudinal axis X1 and the second longitudinal axis X2 are offset from each other to enable the tip of the locking tab to be radially inset. An axial press tool can be used to mount the connector unit mechanically in the housing. The present invention also relates to a method of assembling a connector assembly.

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.

Abstract: A pressurisation pump is provided comprising a first plunger and a second plunger, each plunger being reciprocable within a respective plunger bore defined by a housing, wherein the first and second plungers together with the bores define, at least in part, a pumping volume. The pump also includes an inlet port and an outlet port. An end of the first plunger is arranged to cover the inlet port during a pump delivery stage in which fluid is displaced from the pumping volume and an end of the second plunger is arranged to cover the outlet port during a pump fill stage in which fuel is drawn into the pumping volume. The end of the first plunger and the end of the second plunger are arranged to cover the inlet port and the outlet port respectively during a pump transfer stage during which the pumping volume is maintained.

Abstract: A method of forming a recess in a body having a surface of substantially cylindrical form utilises a grinding wheel having a first axis in the form of a drive axis, and a circumferential surface concave to a second axis that is substantially orthogonal to the first axis. The grinding wheel also includes first and second opposing radial surfaces of substantially planar form. At least a portion of the circumferential surface of the grinding wheel is engaged with an outer surface of the body and the grinding wheel is rotated about the drive axis to cause a region of the body to be ground, thereby to define a recess in the body having a periphery including at least two substantially square corners and at least one pair of substantially parallel facing edges. The method is conveniently used to provide an opening or port of at least partially square or rectangular form in a cylindrical body such as a metering valve.

Abstract: A governor for use in an engine, the governor including a drive shaft and a plurality of weights carried by the drive shaft. The weights are rotatable with the drive shaft and are moveable relative to the drive shaft. A lever is moveable in response to movement of the weights, the lever being moveable against the action of a return biasing arrangement. The governor further includes a further arrangement for holding at least one of the weights against movement so as to permit adjustment of the operating speed of the governor.
