    摘要: A pump head for a fuel pump assembly is described. The pump head (120,120a) comprises a tappet (134) and a pump head main body (122). The tappet (134) has an internal volume and a tappet base (176). The tappet base (176) is adapted to be co-operable with an engine driven cam so as to, in use, impart drive to the tappet (134). The pump head main body (122) comprises an inlet means for admitting fuel at relatively low pressure and an outlet means for expelling pressurised fuel at relatively high pressure. The tappet (134) is adapted to reciprocate with respect to the pump head main body (122). The internal volume of the tappet (134) forms at least a part of a pump chamber (130) for pressurising fuel to be expelled through the outlet means.

    摘要: A volumetric pump (1) comprising at least one first piston (20) inside a first hollow cylindrical part (23). This pump (1) has at least one inlet port (10) through which a liquid (15) can be sucked into at least one pump chamber (26) during an instroke of said piston (20), and at least one outlet port (11) through which the liquid (15) can be expelled during the outstroke of the piston (20). At least one second piston (21) is positioned opposite to the first piston (20) inside a second hollow cylindrical part (23') to create at least a second pump chamber (26') through which the liquid (15) can be sucked in through the inlet port (15) during an instroke of the second piston (21) and expelled through the outlet port (11) during the outstroke of said second piston (21). Both cylindrical parts (23, 23') are assembled end-to-end facing each other to form a housing (22). An element (24), preferably a disc, is mounted midway inside said housing (22). This element (24), which comprises the inlet and outlet ports (10, 11), is arranged to be animated by a preferably combined bidirectional linear and angular movement to cause relative to-and-fro sliding between the cylindrical housing (22) and the pistons (20, 21) along the axis of said pistons (20, 21) while closing the inlet and outlets ports (10, 11) synchronically to ensure a continuous flow delivery.

    摘要: A cryogenic pump is disclosed for pumping liquified gas from one container to another container or a point of use. The pump has a main housing (12) defining a cylinder in which a hollow piston (34) is reciprocable by means of a piston rod (42) and divides the interior of the main housing into a supercharger chamber (50) and a sump chamber (52). The lower end of the main housing is closed by a block (24) formed with a fixed piston (54), defining a high pressure chamber (60) in the hollow piston (34), and with inlet ports (76) leading into the sump chamber (52). An outer housing (14) defines a precharge chamber (82) around the main housing (12). During reciprocation of the hollow piston (34), liquid is drawn in through the ports (76) and progressively pumped, though non-return valves, in sequence through the sump chamber (52), the precharge chamber (82), the supercharger chamber (50), and the high pressure chamber (60) to an outlet line (136). The block (24) is located within and adjacent to the bottom of the container. The pump arrangement allows the container to be substantially emptied thereby avoiding waste of the contained liquified gas.

    摘要: A volumetric pump (1) comprising at least one piston (2) in a hollow cylinder (3), said pump (1) having at least one inlet port (10) through which a liquid (15) can be sucked into a pump chamber (3) during an instroke of said piston (2), and at least one outlet port (11) through which the liquid (15) can be expelled during an outstroke of the piston (2). Said piston (2) or the hollow cylinder (3) of the volumetric pump (1) can be actuated directly or indirectly by at least one rotor (5). This rotor (5) transmits, on the one hand a bi-directional linear movement to the piston (2) or to the cylinder (3) causing said piston (2) to slide back and forth inside said cylinder (3) or following the axis of said piston (2), and on the other hand, a bi-directional angular movement either to the piston (2) or to a disc (24) in order to open and close alternately the inlet and outlet ports (10, 11).

    摘要: The invention relates to a piston pump (10) for a hydraulic, slip-controlled vehicle braking system. The aim of the invention is to reduce the length of said piston pump (10). To this end, a piston (16) of the piston pump (10) is configured as a hollow piston, the inner cavity of this hollow piston forming a displacement chamber (40) of the piston pump (10), and an inlet valve (20) of the piston pump (10) is placed in the inner cavity of the piston (16).
