    • Provided is a seal ring which has low-friction characteristics and low-leakage characteristics, reduces drive loss of the automatic transmission of an automobile, and contributes to improvement in fuel consumption of the automobile. The seal ring is attached to a shaft groove on the outer peripheral surface of a shaft. A plurality of recessed sections circumferentially spaced apart from each other with pillar sections interposed therebetween are formed at least on the inner peripheral side of a side surface of the seal ring in contact with the shaft groove. The circumferential opposite ends of each of the recessed sections are formed as squeezing portions formed of curved surfaces convex toward the pillar sections. The depth “h” of a deepest portion in which the axial width of the recessed section is the largest is set in the range of 2 to 17 where the axial width of the seal ring is 100.
    • 提供了具有低摩擦特性和低泄漏特性的密封环,减少了汽车的自动变速器的驱动损失,有助于提高汽车的燃料消耗。 密封环安装在轴的外周面上的轴槽上。 至少在与轴槽接触的密封环的侧面的内周侧上形成有多个彼此周向间隔开并具有插入其间的柱部分的凹部。 每个凹部的周向相对端形成为由朝向柱部凸出的弯曲表面形成的挤压部。 凹部的轴向宽度最大的最深部的深度“h”设定在密封环的轴向宽度为100的2〜17的范围内。

    • Provided is a seal ring that has low-leakage characteristics and low-friction characteristics and can improve the drive loss of the automatic transmission of an automobile to thereby contribute to an improvement in the fuel consumption of the automobile. The seal ring is attached to a shaft groove formed on the outer peripheral surface of a shaft. A plurality of peripherally spaced recessed sections are formed on at least the inner peripheral side of a contact side-surface. Inner walls are provided on the inner peripheral side of the recessed sections, and oil introduction openings that open on an inner peripheral surface are provided on the inner peripheral side of the recessed sections. The inner walls may be provided on opposite peripheral sides of the recessed sections but may be provided only on the rear side in the rotation direction.

    • An ejector cycle device includes a compressor, a refrigerant radiator disposed to radiate heat of refrigerant discharged from the compressor, an ejector having a nozzle, a first evaporator for evaporating refrigerant from the ejector, a branch passage, which is branched from a refrigerant downstream side of the refrigerant radiator and is connected to a refrigerant suction port of the ejector, a throttle member disposed in the branch passage to decompress refrigerant flowing from the refrigerant radiator, a second evaporator disposed in the branch passage between the throttle member and the refrigerant suction port of the ejector, and a gas-liquid separator having an inlet connected to a downstream side of the first evaporator and an outlet from which gas refrigerant is introduced to a refrigerant suction side of the compressor. Thus, refrigerant amounts flowing to the first and second evaporators can be suitably controlled.
    • 喷射器循环装置包括:压缩机,布置成辐射从压缩机排出的制冷剂的热量的制冷剂散热器,具有喷嘴的喷射器,用于从喷射器蒸发制冷剂的第一蒸发器,从制冷剂下游侧分支的分支通道 并且连接到喷射器的制冷剂吸入口,节流部件,设置在分支通道中以对从制冷剂散热器流动的制冷剂进行减压;第二蒸发器,设置在节流部件和制冷剂吸入口之间的分支通道中 以及气体分离器,其具有连接到第一蒸发器的下游侧的入口和气体制冷剂从该压缩机的制冷剂吸入侧引入的出口。 因此,可以适当地控制流向第一蒸发器和第二蒸发器的制冷剂量。
