摘要： A fuel injection pumping apparatus for supplying fuel to a compression ignition engine has an annular cam ring which has internal cam lobes for imparting inward movement through cam followers respectively to pumping plungers mounted in a rotary distributor member. Stop rings are mounted alongside the cam ring to determine the maximum outward movement of the plungers. The stop rings are angularly adjustable to enable the maximum amount of fuel supplied to the engine to be varied. Two adjusting devices are provided the first being a piston which is subject to a fluid pressure varying with speed. The piston is biased by a spring and sets the stop rings to allow an excess of fuel for engine starting purposes and the second is a diaphragm assembly responsive to the air pressure in the engine inlet manifold. In order to save space the piston is slidable within a housing which also accommodates the diaphragm assembly and the diaphragm assembly is coupled to the stop rings by means of a push rod which passes through an aperture in the piston.

摘要： A fuel pumping apparatus for supplying fuel to a compression ignition engine includes a high pressure pump to which fuel is supplied from the outlet of a low pressure pump of the vane type. The vanes of the pump are mounted in slots in the pump rotor and are spring biased outwardly. A cavity defined by the inner ends of the slots is connected by a spring loaded valve to the outlet when the output pressure is above a predetermined value and to a space in the housing of the apparatus through a valve when the output pressure is below said value. The space contains fuel which accumulates during the operation of the apparatus.

摘要： Apparatus for use in the laying and/or replacement of pipes under ground comprises a casing (1), a frusto-conical impact member (2) secured to one end of the casing and adapted to form an underground passage for the casing when the apparatus is being driven through the ground, a piston (7) reciprocally mounted in the casing and arranged to be driven by a source of compressed air or other fluid to engage the impact member (2) with a series of impacts to drive said member and the casing through the ground and a control valve member (11) adapted to be connected to a source of compressed air or other fluid and arranged to reciprocate the piston in the casing by means of said compressed air or other fluid. A pipe fitting (31) is connected to a tubular spacer member (23) which is mounted on the other end of the casing (1), said pipe fitting being adapted to be clamped to the leading end of a pipeline (29 and/or 30) which is to be laid in the underground passage formed by the impact member (2). The connection between the pipe fitting (31) and spacer member (23) includes a flanged sleeve (25) which permits relative rotation between the pipe fitting and the casing.

摘要： A fuel injection pump has a rotary and axially slidable distributor member housed in a sleeve in which is formed a series of outlet ports and a series of inlet ports the two series of parts being in axially spaced planes. The distributor member has an outlet groove for registration with the outlet ports in turn and an inlet groove for registration in turn with the inlet ports. The two grooves communicate with a pumping plunger bore so that as the distributor member rotates fuel will be supplied to the bore through an inlet port and the inlet groove and will flow from the bore through the outlet groove and an outlet port. Interconnected balancing grooves are provided on the distributor member for communication with the outlet ports and inlet ports respectively to ensure that following delivery of fuel through an outlet port, that port will be connected to an inlet port before the next delivery of fuel through the port takes place.
