    • A vacuum pump connected to a unit where a low pressure is desired to be maintained, is adapted to reduce a rise in its temperature, during extended operations of the pump. A suction channel has a first end connected to a suction port of the pump and a second end connected to the unit. An aperture provided on the suction channel extends to a pre-determined depth with the channel. The aperture is plugged by a fusible material, or a material capable of subliming. As the temperature of the pump rises, the suction channel transfers heat to the plugging layer of the aperture, and the layer melts or sublimes gradually, with the temperature rise. Once the layer has completely melted or sublimed, the apertures aspirate ambient air from the surroundings into the pump, which cools the interior components of the pump, and quickly reduces the pump's temperature.
    • 连接到希望保持低压的单元的真空泵适于在泵的延长操作期间减少其温度的升高。 抽吸通道具有连接到泵的吸入口的第一端和连接到该单元的第二端。 设置在吸入通道上的孔径延伸到通道的预定深度。 孔被可熔材料或能够升华的材料堵塞。 当泵的温度升高时,吸入通道将热量传递到孔的堵塞层,并且层随着温度升高而逐渐熔化或升华。 一旦该层完全融化或升华,孔将环境空气从环境吸入泵中,该空气冷却泵的内部部件,并快速降低泵的温度。

    • A gaseous fluid compression device includes: a first enclosure within which there is a movable first piston delimiting a first chamber and a second chamber; a second enclosure within which there is a movable second piston delimiting a third chamber and a fourth; a first exchange circuit connecting the first chamber and the fourth chamber, with a heat exchanger linked to a heat sink; a second exchange circuit connecting the second chamber and the third chamber, with a second heat exchanger linked to a heat source; and a transfer passage connecting the first chamber and the second chamber with an anti-backflow device. A back-and-forth movement of the interconnected pistons results in a compression of the gaseous fluid in the direction of the outlet.
    • 气态流体压缩装置包括:第一外壳,其中存在限定第一室和第二室的可移动的第一活塞; 第二外壳,其中存在限定第三室的可动第二活塞和第四壳体; 连接第一室和第四室的第一交换电路,连接到散热器的热交换器; 连接第二室和第三室的第二交换回路与连接到热源的第二热交换器; 以及连接第一腔室和第二腔室的防反流装置的传送通道。 相互连接的活塞的往复运动导致气体流体在出口的方向上的压缩。

    • In one aspect, there is provided a heat pump system which comprises an enclosure and an electrostatic compressor. The enclosure is substantially filled with a first fluid and includes a plurality of compressor vanes, a heat exchanger, and a control module. The plurality of compressor vanes are responsive to electrical stimulus and are substantially separated from each other so that the first fluid extends to and at least partially occupies a space between adjoining pairs of the compressor vanes. The heat exchanger is thermally coupled to the first fluid in the space between the compressor vanes and to a second fluid substantially outside the enclosure. The control module is responsive to input information and includes an electrical circuit that provides the electrical stimulus to the compressor vanes. The compressor vanes respond to the electrical stimulus by compressing and releasing the first fluid between the adjoining pairs of compressor vanes.
