摘要： An object of the present invention is to provide a pump which suppresses a decrease in the volumetric efficiency of the pump to a great extent even in case that the kinematic viscosity of a fluid is high with a compact structure of the pump itself. The present invention, a pump provided with a first pump mechanism and a second pump mechanism comprises a housing having therein a first pump chamber, a second pump chamber, an intake port communicated with the first pump chamber, and a discharge port communicated with the second pump chamber, first valve means which open the communicating passage when the second pump chamber is compressed and close the communicating passage when the second pump chamber is expanded, a piston which expands the second pump chamber when the first pump chamber is compressed, and compresses the second pump chamber when the first pump chamber is expanded in accordance with movement thereof, second valve means which open so as to permit fluid to flow into the first pump chamber when the first pump chamber is expanded and close so as to prevent fluid in the first pump chamber from flowing out of the first pump chamber when the first pump chamber is compressed, and third valve means which open so as to discharge pressurized fluid in the second pump chamber when the second pump chamber is compressed and close when the second pump chamber is expanded.

摘要： A valve assembly is disclosed for an oscillating pump of the type having a reciprocating armature carrying an impeller that defines a pump chamber for flow of fluid through the pump. The valve assembly includes a valve body mounted to the impeller, a valve seat attached to the valve body, a spring retainer, a spring mounted to the spring retainer and a plug located between the spring and the valve seat. The valve assembly provides a substantially fluid tight seal when the pump is discharging fluid and allows fluid to enter the pump chamber when the pump is suctioning. All wetted components are particularly suitable for corrosive fluids, such as acids.

摘要： An improved quick-change fluid section for piston-type paint pumps having a mounting flange with keyhole shaped apertures at one end and a threaded fitting at the other end to couple a fluid section housing to driving means via a slide housing. The piston and slide are retained in reciprocable driving relationship via a transverse pin held in place by a circumferential spring received in a circumferential groove on the slide. The spring and pin are accessible via diametrically opposed apertures in the mounting flange. The fluid section housing is bifurcated and has sealing means which may be either a packing set of alternating elastomeric and leather V-rings or lip-type seals. The sealing means is immediately available upon separation of the two portions of the fluid section and may be removed without the need for special tools. An inline or right angle inlet or suction fitting may be utilized with the fluid section.

摘要： A side entry down-hole pump for oil wells which relies upon gravity rather than suction to receive incoming oil. A pump barrel is plugged at its bottom end and is anchored in the well. A pair of inlet slots in the side of the pump barrel admit oil to a pump chamber formed in the barrel between the inlet slots and the closed bottom end of the barrel. A pumping element is formed by a plunger assembly which includes a cup body carrying a pair of cup shaped seal rings. A pumping string reciprocates the pumping element up and down and provides a flow passage through which oil is pumped to the surface. During upstrokes, the seal rings move above the inlet slots so that oil flows by gravity through the slots and into the pump chamber. Downstrokes effect compression of oil in the pump chamber to pump it through the flow passage and through a check valve which prevents downflow of oil. A pair of discharge slots in the pump barrel relieve pressure created by oil trapped above the seal rings.
摘要翻译：用于油井的侧入式井下泵，其依赖于重力而不是抽吸来接收进入的油。泵筒在其底端被堵塞并且锚固在井中。在泵筒一侧的一对入口槽允许油在形成在筒体中的泵室之间进入入口槽和筒的封闭底端之间。抽吸元件由柱塞组件形成，柱塞组件包括承载一对杯形密封环的杯体。泵送柱将泵送元件上下往复运动，并提供一个流动通道，油被泵送到表面。在上冲时，密封圈在入口槽的上方移动，使得油通过重力流过槽并进入泵室。冲击效应压缩泵室中的油，以将其泵送通过流动通道并通过止回阀，以防止油的下流。泵筒中的一对排放槽减轻了由密封环上方的油产生的压力。

摘要： A subsurface pumping installation in which solvent or diluent is introduced to the well from the surface and blends with the well fluid to enable it to be pumped more readily. The diluent is introduced through a power tubing which may be either concentric with the casing or concentric with a production tubing within the casing. A mixture of well fluid and diluent is conducted to the surface through an annulus which surrounds the power tubing. The diluent is injected into the well fluid in a blending chamber inside the pump, where it blends effectively without loss into the formation around the pump.

摘要： A hydraulic pump comprises a pair of chambers and a plunger which extends axially through both chambers and provides a valvecontrolled fluid flow path between the two chambers such that fluid is transferred from one chamber, acting as a reservoir, to the other chamber in response to reciprocation of the plunger. The plunger is displaceable by means of a lever system which is effective to vary the rate of displacement of the plunger so that plunger travel for a given lever movement is greater initially than towards the end of the plunger stroke. The lever system is arranged so that it imparts only substantially axial forces to the plunger during reciprocation thereof.
