摘要： The device is a hand pump which has a hand lever pivoted at 61 to lugs 60 and actuating pumping pistons 22 and 23 to draw fluid from a reservoir cylinder mounted in recess 58 in the base component of the pump. The body 19 of the base component is extruded from aluminium which is easily machined to provide the piston and valve passages. A sleeve 27 is mounted in the body 19 to receive the piston 22 and is secured to the body by an encapsulating housing 20 moulded from fibre-reinforced synthetic resin. The housing 20 includes the lugs 60 and is designed to withstand the stresses imposed during operation of the pump.
Also described are an alternative design of hand pump, a hydraulic cylinder and a hydraulic valve all having two components joined together by encapsulation.

摘要： A check valve assembly comprising a housing having a fluid inlet (112) arranged to be fluidly connected, in use, to a source of hydraulic fluid, a first stage body (122) having a first stage fluid outlet (128) and a second stage body (124) having a second stage fluid outlet (228) and a flow passage (126) between the first stage body and the second stage body, wherein the first stage body is a hollow body having a first end in fluid communication with the fluid inlet (112) and housing a hollow first stage retainer (140) around which is mounted a first stage spring (142) that biases a first stage ball (150), and wherein the second stage body is a hollow body housing a second stage retainer (130) around which is mounted a second stage spring (132) that biases a second stage ball (160), and wherein a first stage pressure differential between the first stage fluid outlet and the fluid inlet creates a fluid flow path from the inlet to the first stage fluid outlet and causes the first stage ball to press against the bias of the first stage spring to close the flow passage between the first stage body and the second stage body, and wherein removal of the first stage pressure differential causes the first stage spring to return the first stage ball to its biased position to close the flow path from the fluid inlet to the first stage fluid outlet and to open the fluid passage between the first stage body and the second stage body and a second stage differential pressure between the fluid passage and the second stage outlet presses the second stage ball against the bias of the second stage spring to open a second stage fluid flow path between the fluid passage and the second stage fluid outlet.

摘要： Method and apparatus overcoming gas-lock in reciprocating downhole pumps. On the downstroke of a plunger in a barrel, gassy fluid is compressed in the pump chamber between standing and travelling valves. Downhole plunger movement drags a sleeve over a mandrel for opening a chamber valve to a staging chamber located at a downhole end of the travelling valve for receiving at least a portion of the compressed and gassy fluid therein. On the upstroke, the chamber valve is dragged closed for sealably retaining the compressed gassy fluid therein while drawing an additional increment of fluid through the standing valve into the pump chamber. Continued downstroke and upstroke cycles increases pressure of the compressed gassy fluid in the pump chamber until it exceeds the hydrostatic head above the travelling valve for resumption of normal fluid pumping.

摘要： As tube-phragm pump includes a pump head (1) and an electromagnetic driver (2). The pump head (1) includes a cylinder (21) having a cylindrical space formed therein, and a cylindrical flexible tube (22) arranged coaxially within the cylindrical space of the cylinder (21). The outer space between the tube and the cylinder defines an actuator fluid space to be filled with an actuator fluid, and the inner space within the tube defines a pump chamber for conveying an object fluid. The pump head also includes an intake valve (31) attached to one end portion of the flexible tube (22) and a discharge valve (42) arranged at the other end portion of the flexible tube (22). The electromagnetic driver (2) includes a plunger (71) arranged reciprocally movable in the axial direction, an electromagnet for periodically attracting the plunger (71) to drive it in the axial direction reciprocally, and diaphragm (52).
