    摘要： A valve assembly for controlling the rate of flow of fluid between a valve inlet (18) and a valve outlet (22) comprises a valve housing (10), and a spool valve member (14) that is movable axially within a valve bore (12) provided in the valve housing (10) in an opening direction and a closing direction. The spool valve member (14) is provided with a blind bore (28), the open end of which communicates with the valve outlet, and at least one opening (32, 34; 40; 50, 52, 54, 56) into the blind bore, the at least one opening communicating, to a variable degree dependent on the axial position of the spool valve member (14) within the valve bore (12), with the valve inlet (18). The valve inlet (18) comprises a first boundary (24) and a second boundary (26), wherein the first boundary (24) acts as a control edge so that for axial positions of the spool valve member (14) in which the opening (30, 32; 40; 50, 52, 54, 56) does not overlap the control edge there is no flow into the outlet (22). A blind end (30) of the blind bore (28) is positioned, for all positions of the spool valve member (14) within the valve bore (12), beyond the second boundary (26) in the opening direction of the spool valve member (14).

    摘要： A method of manufacturing a metal housing (14) includes providing a first passage (10) through the metal housing (14) and providing a second passage (12) through the metal housing (14), wherein the second passage (12) includes a region of intersection (20) which intersects the first passage (10) to define an opening (22, 122, 222) into the first passage (10). The method further includes subjecting the metal housing (14) to a heat treatment process to carburise an internal surface of the first and/or second passage (10, 12) and, subsequent to the carburisation process, applying a hard stage electrochemical machining process to the carburised internal surface of the first and/or second passage (10, 12) to improve surface finish. Another aspect of the invention includes providing a second passage (12) through the metal housing (14) by means of a tool (46), such as an electrochemical machining electrode, having an active region without rotational symmetry about its axis (Y-Y). The active region is shaped to provide the region of intersection (20) with a generally conical taper (29, 31) to the opening (22; 122; 222).

    摘要： A fuel injector for an internal combustion engine, the fuel injector comprising an injector body, a fuel supply passage defined in the injector body, the fuel supply passage containing fuel under high pressure in use of the injector, a pressure sensor for measuring the pressure of fuel in the passage in use, wherein the pressure sensor is situated within the injector body and is separated from fuel in the passage in use, and a method of fuel injection, comprising constructing an hydraulic behaviour profile by fuel pressure measurement, using the hydraulic behaviour profile to predict fuel pressure that will prevail in a fuel injector during an injection event, and supplying a control signal to the fuel injector to control the amount of fuel injected during the injection event in accordance with the predicted fuel pressure. By predicting the fuel pressure that will prevail during an injection event, the fuel delivered during the injection event can be accurately controlled.
