摘要： Variable displacement compressor comprising a housing; piston; and drive shaft rotatably supported by the housing; a rotor rotating in unison with the drive shaft; a swash plate that rotates in synchronism with the rotation of the connected rotor. Rotation of the swash plate is converted into a reciprocating motion of the piston; and a pressure control valve that is capable of controlling the internal pressure of a crank chamber. The swash plate is connected to the rotor in an inclined fashion such that, as viewed from a site on the swash plate corresponding to the top dead center position of the piston, a compression process region toward the positive direction of the rotation of the swash plate is farther away from the bearing surface of a thrust bearing, which is formed on the rotor, than a suction process region toward the negative direction of the rotation of the swash plate.

摘要： A high pressure pump includes a pump body, a pressurizing chamber, a fuel passage, a union, a seat member, a relief valve seat, a relief valve, a discharge valve seat, a discharge valve, a spring and a spring holder. The union has an inner threaded portion and a step portion formed on an inner wall of the union. The seat member includes a relief passage that extends through the seat member in an axial direction of the seat member and a discharge path that is not in fluid communication with the relief passage. The one opening of the relief passage is closer to the pressurizing chamber than an other opening of the relief passage is to the pressurizing chamber. The one opening of the discharge path is further from the pressurizing chamber than an other opening of the discharge path is from the pressurizing chamber. The seat member is pressed toward the step portion when the spring holder is fastened to the union by engaging the inner threaded portion with the outer threaded portion.

摘要： Pump assemblies for use with a subsurface fluid reservoir include an upper portion connected to a fluid conduit extending to the surface, a lower portion connected to the upper portion and in fluid communication with a fluid reservoir of the wellbore, and a plunger assembly movably located within the upper and lower portion of the pump assembly. As the fluid pressure within the tubing string, fluidly isolated from the fluid conduit, increases, fluid is forced into the pump assembly moving the plunger assembly upwell to draw fluid into the pump and forces fluid into the fluid conduit. As the fluid pressure within the tubing string decreases, movement of the plunger assembly forces fluid from the lower portion into the upper portion through a fluid passageway extending through the plunger assembly.
摘要翻译：与地下流体储存器一起使用的泵组件包括连接到延伸到表面的流体导管的上部部分，连接到上部并与井眼的流体储存器流体连通的下部分，以及可移动地位于泵组件的上部和下部。随着流体导管中流体隔离的油管柱内的流体压力增加，流体被迫进入泵组件中，使柱塞组件向上移动以将流体吸入泵并迫使流体进入流体导管。当管柱中的流体压力减小时，柱塞组件的运动通过延伸穿过柱塞组件的流体通道将流体从下部部分压入上部。

摘要： The invention provides a device for extracting energy from a liquid flow. The device has a housing with one or more entry ports through which liquid flow can enter the housing and a plurality of exit ports through which liquid flow can leave the housing. An air compression chamber is provided along with a plurality of valve members which are operable to regulate flow of the liquid through the plurality of exit ports. The exit ports are arranged in an array inclined in the direction of liquid flow and the valve members are operable to close the exit ports downstream of the liquid flow consecutively as the liquid flow is incident thereon, thereby progressively diverting flow of the liquid towards the air compression chamber and compressing air therein, and to open the exit ports on a return flow of liquid from the air compression chamber.

摘要： Embodiments of the present invention relate generally to certain types of reciprocating positive-displacement pumps (which may be referred to hereinafter as “pods,” “pump pods,” or “pod pumps”) used to pump fluids, such as a biological fluid (e.g., blood or peritoneal fluid), a therapeutic fluid (e.g., a medication solution), or a surfactant fluid. The pumps may be configured specifically to impart low shear forces and low turbulence on the fluid as the fluid is pumped from an inlet to an outlet. Such pumps may be particularly useful in pumping fluids that may be damaged by such shear forces (e.g., blood, and particularly heated blood, which is prone to hemolysis) or turbulence (e.g., surfactants or other fluids that may foam or otherwise be damaged or become unstable in the presence of turbulence).
