    • 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.

    • 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.
    • 一种用于活塞式涂料泵的改进的快速流体部分,其具有在一端具有锁眼形孔的安装凸缘和在另一端的螺纹接头,以通过滑动壳体将流体部分壳体联接到驱动装置。 活塞和滑块通过容纳在滑块上的圆周凹槽中的圆周弹簧保持在适当位置的横向销保持往复运动。 弹簧和销可通过安装法兰上的直径​​相对的孔进入。 流体部分壳体是分叉的并且具有密封装置,该密封装置可以是交替弹性体和皮革V形环或唇形密封件的填充组。 密封装置在分离流体部分的两个部分时立即可用,并且可以在不需要特殊工具的情况下被移除。 流体部分可以使用直列或直角入口或抽吸接头。

    • 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.
    • 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。
