摘要： A pressurisation pump (10) is provided comprising a first plunger (12a,12aF,12b) and a second plunger (12a,12aP,12b), each plunger being reciprocable within a respective plunger bore (26,28) defined by a housing (14), wherein the first and second plungers (12a,12aF,12aP,12b) together with the bores (26,28) define, at least in part, a pumping volume (23). The pump also includes an inlet port (22) and an outlet port (24) associated with the first and second plungers (12a,12aF,12aP,12b). An end of the first plunger (12a,12b,12aF) is arranged to cover the inlet port (22) during a pump delivery stage in which fluid is displaced from the pumping volume, and an end of the second plunger (12a,12b,12aP) is arranged to cover the outlet port (24) during a pump fill stage in which fuel is drawn into the pumping volume.

摘要： An hydraulic pump (100) comprises a plurality of pumping bores (16a - 16d), each pumping bore (16a - 16d) including an inlet port (32a - 32d) for the supply of hydraulic fluid into said pumping bore (16a - 16d), a delivery port (30a - 30d) for the delivery of said hydraulic fluid from said pump (100) and a plurality of pump plungers (20a - 20d), each pump plunger (20a - 20d) being reciprocable within a respective one of said pumping bores (16a - 16d). Each pump plunger includes a head portion (22a - 22d) and a skirt portion (24a - 24d), and each pump plunger (20a - 20d) defines with said pumping bore (16a - 16d) a pumping chamber (23a - 23d) disposed between said head portion of said pump plunger and one end of said pumping bore and a transfer chamber disposed between said head portion (22a - 22d) and said skirt portion (24a - 24d) of said pump plunger (20a - 20d). The pump also includes communication means connected between the pumping chamber of each pumping bore and the transfer chamber of an adjacent pumping bore, and drive means (140) for reciprocably driving each of the pump plungers (20a - 20d) within said pumping bores (16a - 16d) such that hydraulic fluid is drawn into said pumping chamber through the inlet port of an adjacent pumping bore and pumped from said pumping chamber through the delivery port of said adjacent pumping bore. The drive means (140) includes means for temporarily halting at least one of the pump plungers (20a - 20d) during a part of its stroke.

摘要： A method of forming a recess in a body (10; 24) having a cylindrical surface, and in particular a metering valve component, utilises a grinding wheel (32) having a first axis (33), preferably a drive axis, and a circumferential surface (34) concave to a second axis (37) that is substantially orthogonal to the first axis (33). The grinding wheel (32) also includes first and second opposing radial surfaces (36, 38) of substantially planar form. At least a portion of the circumferential surface (34) of the grinding wheel (32) is engaged with an outer surface of the body (10; 24) and the grinding wheel (32) is rotated about the drive axis (33) to cause a region of the body (10; 24) to be ground, thereby to define a recess (40; 46) in the body having a periphery (42; 48) at the cylindrical surface including at least two substantially square corners (41a, 41b, 41c, 41d; 49a, 49b) and at least one pair of substantially parallel facing edges (43a, 43b, 43c, 43d; 47a, 47b). 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 member (24) or a metering valve sleeve (10) of a metering valve arrangement.
