    摘要： A multicylinder rotary compressor has a plurality of cylinders housing rolling pistons which are rotated inside the cylinders by a common crankshaft. Each cylinder has a separate suction pipe. At least one of the suction pipes has a check valve which may be closed to unload the cylinder to which the suction pipe is connected. The check valve has a housing and a slider which can slide inside the housing between an open position and a closed position. The check valve may be closed by introduction of high-pressure refrigerant gas into the space beneath the slider to push it to the closed position when a cylinder is to be unloaded. In another form of the invention, the check valve is closed by a spring made of a shape-memory alloy and a heater for heating the spring above a prescribed temperature at which the allow changes shape. When a cylinder is to be unloaded, the heater is turned on, and the shape-memory alloy deforms into a shape such as to force the slide to the closed position. Lubricating oil may be provided to an unloaded cylinder.

    摘要翻译： 多缸旋转压缩机具有容纳滚动活塞的多个气缸，其通过公共曲轴在气缸内旋转。 每个气缸都有一个单独的吸入管。 抽吸管中的至少一个具有止回阀，该止回阀可以被关闭以卸载与吸入管连接的气缸。 止回阀具有壳体和滑块，其能够在开启位置和关闭位置之间在壳体内滑动。 可以通过将高压制冷剂气体引入到滑块下方的空间中来将止回阀关闭，以便在要卸载气缸时将其推到关闭位置。 在本发明的另一形式中，止回阀由形状记忆合金制成的弹簧和用于在允许变化形状的规定温度以上加热弹簧的加热器封闭。 当汽缸要卸载时，加热器被打开，并且形状记忆合金变形成一种形状，以将滑块迫使到关闭位置。 润滑油可以提供给一个无负载的气缸。

    摘要： A discharge valve is incorporated into a scroll compressor for use in a refrigerator or an air conditioner. A valve element seating surface having a concave cylindrical shape is formed in the upper surface of the stationary disk of the stationary scroll plate of the scroll compressor, a discharge port is formed through the stationary disk of the stationary scroll plate so as to open in the valve element seating surface, and a discharge valve element having a cylindrical shape conforming to the concave cylindrical shape of the valve element seating surface is seated on the valve element seating surface so as to open or close the discharge port. The valve element seating surface having a concave cylindrical shape facilitates machining the stationary scroll plate, reduces the top clearance of the scroll compressor without reducing the rigidity of the stationary disk, prevents the concentration of stress on the delivery valve, and improves the reliability of the delivery valve.

    摘要： A low pressure container type rolling piston compressor which includes a compression element, a motor element, a rotary shaft with an eccentric portion driven by the motor element, a cylinder for receiving therein the eccentric portion of the rotary shaft, a rolling piston having an inner circumference to which the eccentric portion is fitted and an outer circumference which rolls along the inner wall surface of the cylinder, a vane having an end which is in contact with the outer circumference of the rolling piston to divide the inner space of the cylinder into a high pressure chamber and a low pressure chamber, a pair of bearing plates for closing both open ends of the cylinder, a sealing container housing the above-mentioned structural elements and storing at its lower part a lubricating oil wherein a pressure in the sealing container is the same as that in the low pressure chamber and wherein an oil supplying passage is formed in either one of the pair of bearing plates for closing both open ends of the cylinder so as to communicate the low pressure chamber with the inner space of the rolling piston rolling in the cylinder.
