Abstract: Mixing a pumped fluid with a lubrication fluid within a pump can undermine the lubricity of the lubrication fluid. In order to reduce mixing of fluids within a pump of the present disclosure, a pump is provided that comprises a housing, a piston, a first annulus, and a second annulus. The housing includes an inlet for the pumped fluid, an inlet for the lubrication fluid provided at a first pressure, and a piston bore fluidly coupled to the inlet for the pumped fluid. The piston is moveable within the piston bore. The first annulus is fluidly coupled to the inlet for the lubrication fluid. The second annulus is configured to be fluidly coupled to a drain circuit provided at a second pressure less than the first pressure. The first annulus and the second annulus are located along the length of the piston bore.

Abstract: La présente invention élimine les désavantages du solénoïde hélicoïdal de l'art antérieur en proposant un agencement unique d'un enroulement de bobine et une construction de noyau modulaire qui non seulement permettent un assemblage rapide et économique de solénoïde de diverses dimensions produisant des forces d'intensité différente mais éliminent la tendance de l'induit à tourner par rapport au noyau. Le solénoïde à réponse rapide (10) comprend un premier et un second organe magnétisables (12, 14) montés de manière télescopique avec un mouvement axial rotatif. Le premier organe interne (12) comprend un nombre sélectionnable de sections modulaires identiques individuelles (16) qui définissent d'une manière collective une pluralité de fentes circulaires espacées longitudinalement (18). Le second organe externe (14) est formé en deux moitiés (14a, 14b) et comprend une pluralité de projections en forme d'anneaux espacées longitudinalement (20) qui s'étendent respectivement dans les fentes (18). On fait tourner certaines de ces sections (16) de 180o pendant l'assemblage de manière à générer des flux de courants dirigés en sens opposés dans les portions d'enroulement (38) des sections adjacentes (16).

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).
