摘要： A double-acting reciprocating pump comprises a piston assembly comprising at least one piston disposed within at least one piston cylinder for undergoing opposite reciprocal movements within said at least one piston cylinder, an upper pump chamber disposed above the piston, and a lower pump chamber disposed below the piston. A fluid inlet is fluidically connected to one of the upper and lower pump chambers so as to supply fluid thereto, and a fluid outlet dispensing port is defined within a lower end portion of the double-acting reciprocating pump assembly for permitting fluid to be dispensed out from the double-acting reciprocating pump assembly during both of the opposite reciprocal movements.

摘要： A piston is the driven component within a pump. The piston is driven along a longitudinal axis to pump a fluid through the pump. The fluid flows through the piston between an upstream end of the pump and a downstream end of the pump. The piston outputs the fluid into the downstream end of the pump at a vector offset from the longitudinal axis, thereby inducing rotation of the piston throughout the pumping process. Rotating the piston encourages even wear on various components within the pump, such as sealing rings surrounding the piston, thereby increasing the lifespan of the components and increasing the efficiency of the pump.

摘要： A piston rod and piston head are the driven components within a pump. An upstream end of the piston rod is attached within an aperture of the piston head. At least one flute extends between the upstream end of the piston rod and the aperture, and the at least one flute is configured to provide a flowpath for a fluid, such as paint, to flow downstream of the piston head and piston rod. The flutes facilitate a smooth downstream flow of the fluid, thereby reducing hydraulic resistance and reducing wear caused by the fluid.

摘要： A reciprocating pump includes an open-bottomed barrel adapted for attaching to the lower end of a production tubing string; a seating assembly having a cylindrical bore and adapted for mounting to a seating nipple at the upper end of the barrel; and a plunger assembly adapted for attaching to the lower end of a sucker rod string. The plunger assembly includes concentric upper and lower plunger sections interconnected by a double-valve, ported valve cage. The plungers are sized for sealing reciprocating engagement within, respectively, the bore of the seating assembly and the bore of the pump barrel. The lower plunger and the ported valve cage define a production chamber within the pump barrel. The upper plunger has ports allowing fluid flow from the tubing into the production chamber. Optionally, the upper plunger and the barrel may be provided with flush ports facilitating flushing of the pump to eliminate vapor lock.

摘要： A piston pump for the hydraulic energy supply in a motor vehicle, comprising a piston that is movably arranged in a stepped bore of an accommodating member that is provided with a closure, the piston carries a seat for an elastic sealing element which accommodates the sealing element with axial play, and with radial elastic preload for the purpose of sealing between piston and cylinder. The seat for the sealing element has a structure which generates forces pointing radially towards a piston axis and expanding the sealing element in a radial direction, and that the structure produces an elastic deformation of the sealing element for an increased and dosed sealing contact pressure between piston and cylinder.

摘要： A sealing structure is provided wherein an annular groove formed in a pump cylinder of a piston pump receives therein a seal ring made of a synthetic resin material and having an inner circumferential surface fluid-tightly contacting an outer circumferential surface of the pump piston and an O-ring arranged on the outer circumferential side of the seal ring and urging the seal ring radially inward. The seal ring is formed at its axial end portions with flange portions for preventing the O-ring from coming off. In the state that the seal ring and the O-ring are fitted in the annular groove, the flange portions do not receive a load from the O-ring, and a surface pressure which the seal ring applies to the outer circumferential surface of the piston at an axial center portion thereof is set to be higher than surface pressures which it applies to the outer circumferential surface of the piston at axial end portions thereof.
