摘要： A piston pump includes a pump mechanism for changing a volume of a pump chamber to move a piston in a housing, and a feed mechanism that has a feed ring attached to a circular groove portion of the piston to be slaved with a movement of the piston. The feed mechanism is located in a suction passage from a suction port to a pump chamber, and the piston has a flange portion protruding radially outwardly. An inner peripheral surface of the feed ring has an inner-diameter enlarged portion extending radially outwardly to have an enlarged passage portion between the inner peripheral surface of the feed ring and the outer peripheral surface of the piston, and a valve portion for opening and closing a suction passage is constructed of an end portion of the inner diameter enlarged portion of the feed ring and the flange portion.

摘要： A pump element includes a pump element housing defining a pump chamber having an inlet and an outlet, and at least a first movable element movable in the pump chamber between a first and a second position. During a movement of the first movable element in the direction from the first to the second position, a flow resistance of a flow path from the first movable element through the inlet is larger than a flow resistance of a flow path between the pump element housing and the first movable element. During a movement of the first movable element in the direction from the second position to the first position, a flow resistance of a flow path from the first movable element through the outlet is smaller than a flow resistance of the flow path between the pump element housing and the first movable element. Thus, during a reciprocating movement of the first movable element between the first and the second position, a net flow through the outlet takes place.

摘要： A positive displacement pump for pumping fluids from a downhole formation to the earth's surface is provided. The pump first comprises a plunger. The plunger is reciprocated axially within the wellbore by a linear actuator, such as a submersible electrical pump, in order to form an upstroke and a downstroke. A pump inlet is disposed near the bottom end of the plunger, while a pump outlet is disposed near the top end of the plunger. The pump is configured such that it is able to pump a first volume of fluid upward within the wellbore during the pump's upstroke, and a second volume of fluid upward within the wellbore during the pump's downstroke. Thus, the pump is “double-acting.”

摘要： A hydraulic oil well pumping installation includes a down hole pump positioned down a well, the down hole pump including a master cylinder and at least one slave cylinder in axial alignment with the master cylinder. A master piston is positioned in the master cylinder and divides the master cylinder into a first portion and a second portion.

摘要： A pump having an increased energy efficiency is provided. The pump has an internal power fluid column and a transfer piston which is reciprocatingly mounted about the power fluid column. The transfer piston defines a product fluid chamber, located above the transfer piston valve, and a transfer chamber, located below the transfer piston valve. The power fluid column has at least one passageway, which allows the fluid inside the power fluid column to be in communication with a power fluid chamber. The power fluid chamber, the transfer chamber, and the product chamber are situated coaxially about the power fluid column.

摘要： A suction valve for reciprocating compressor includes a fixation part, which receives a driving force of a reciprocating motor, and is fixed-combined to the front end surface of a piston performing linear reciprocal movement in the cylinder, a switching part for switching a hollow channel formed to penetrate the piston having a certain area, and a plurality of arms for connecting the switching part and the fixation part to make the switching unit behave in a certain displacement section having the fixation part as a fixed point. Receiving driving force of the reciprocating motor, the piston is bent and straighten by the pressure difference, and stress is distributed evenly in the above process, and minimizing bulking phenomenon to prevent damage of a switching part. Also, the responsiveness of the valve can be improved.

摘要： A pump apparatus includes a housing having a bore formed therethrough. A piston is disposed within the bore for reciprocal movement therein. The piston includes a piston body, and an inlet flange extending radially outwardly from the piston body. An outer peripheral surface of the inlet flange and a wall of the bore define a first passageway. A retaining flange extends radially outwardly from the piston body and have a substantially square transverse section. An outer peripheral surface of the retaining flange and the wall of the bore define a second passageway. An intermediate portion is disposed between the inlet flange and the retaining flange. An annular seal is disposed around the intermediate portion of the piston body. The seal slidingly engages the wall of the bore, and the seal and the piston cooperate to form a check valve assembly.
