Abstract: A liquid pump (20) includes an electronically controlled throttle inlet valve (50) to control pump output. With each reciprocation cycle, a plunger (26) displaces a fixed volume of fluid. When less than this fixed volume is desired as the output from the pump, the electronically controlled throttle inlet valve (50) throttles flow past a passive inlet check valve (30) to reduce output. As a consequence, cavitation bubbles are generated during the intake stroke. Cavitation damage to surfaces that define the inlet port passage (48, 148, 248, 348, 448, 548) are avoided by a specifically shaped and sized cavitation flow adjuster (39, 139, 239, 339, 439, 539) extending from the valve member (33) of the passive inlet check valve (30). By positioning the cavitation flow adjuster (39, 139, 239, 339, 439, 539) in the inlet port passage (48, 148, 248, 348, 448, 548), a flow pattern is formed in a way to encourage cavitation bubble collapse away from surfaces that could result in unacceptable cavitation damage to the pump.

Abstract: Mixing of lubrication fluid and pumped fluid within a pump can undermine lubricity of the lubrication fluid and/or contaminate the pumped fluid (e.g. fuel) with lubrication fluid. In order to reduce mixing of fluids within a high pressure pump (14) of the present disclosure, a lubrication fluid is supplied to the high pressure pump (14). A low pressure pump (15) supplies a second fluid to the high pressure pump (14). The pressure of the second fluid is increased within at least one piston bore (33) of the high pressure pump (14). Mixing of the lubrication fluid and the second fluid is reduced by fluidly connecting a weep annulus (40) which is opened to the at least one piston bore (33) to a low pressure pump inlet (26) of the low pressure pump (15).

Abstract: A valve-closed-orifice (VCO) spray tip (14) having an internal tip seat (18) and one or more fuel spray orifices (20). The thickness of the tip (14) in the wall portion defining the internal tip seat (18) and upstream entrance of each orifice is made less than that of previously known VCO tips. The length to diameter ratio of each orifice (20) is also relatively smaller than that of previously known VCO tips. Advantages of the thinner wall portion include improved fuel injection spray characteristics as well as reduced cost of forming orifices (20) through the tip (14).

Abstract: A component includes a transmission arrangement for transmitting a force between an actuator (102) and a control valve (172). The transmission arrangement includes a post (116) that is associated with the actuator (102). The control valve (172) is displaceable to an open position from a closed position when an opening (124) force is applied to the control valve (172) that is greater than a closing force provided to the control valve (172). The transmission arrangement is disposed in the component between the post (1 16) and the control valve (172) actuator (102) and arranged to mechanically transmit by physical contact an actuator (102) force from the post (116) to the control valve (172) when the post (116) begins to travel towards the extended stroke position, and hydraulically amplify the actuator (102) stroke between the post (116) and the control valve (172) when the post (116) travels from the retracted stroke position to the extended stroke position.
