    Abstract: A pumping element (900) for pressurizing a fluid within a fluid pump (100) has a fuel pump housing (904) disposed around the pumping element (900). A plunger (908) reciprocates within a bore (906) defined in a barrel (122), which define a pressurization chamber (910) into which fluid is pressurized. A flow (409) path is defined between the plunger (908) and the bore (906). The flow (409) path permitting fluid to pass from the pressurization chamber (910) during pressurization of fluid. A collection chamber formed between the plunger (908) and the bore (906) is disposed adjacent to the bore (906). At least one weep opening defined in the barrel (122) is fluidly connected to the collection chamber, and n annular reservoir (306) defined between the barrel (122) and the fuel pump housing (904) is disposed to receive fluid via the at least one weep opening.

    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).
