  • Patent number: 11378133
    Abstract: A damper device includes first and second rotary members, elastic members, and seat members. The first rotary member includes an annular chamber, and first engaging portions provided in the annular chamber. The second rotary member includes a second engaging portion. The elastic members are aligned in a circumferential direction in the annular chamber, and elastically couple the first and second rotary members in a rotational direction. Each seat member is disposed between a circumferential end surface of each elastic member and both the first engaging portions and the second engaging portion. Each seat member includes first and second contact surfaces. The first contact surface contacts the circumferential end surface of each elastic member. The second contact surface contacts the second engaging portion. The first and second contact surfaces tilt at angles to prevent a radially outward force from acting on each seat member when each elastic member is elastically deformed.

  • Publication number: 20220049908
    Abstract: A receiver includes a large diameter main body portion, and an intermediate member side small diameter portion. A wall thickness of the intermediate member side small diameter portion is smaller than a wall thickness of the main body portion. As a result, heat capacity of the intermediate member side small diameter portion is reduced. As a result, it is possible to complete brazing between the intermediate member side small diameter portion and the intermediate member, at the same time as brazing among tanks, tubes, and fins. A desiccant enclosed in a flexible bag can be taken in and out through the intermediate member side small diameter portion.

  • Publication number: 20070071920
    Abstract: A heat exchanger tube improved in endurance to chipping, while securing performance, by changing the tube specifications, wherein, for example, fluid circulating holes are formed to be substantially rectangular in cross-section, and, when a width direction thickness of a front side wall part of the tube is “T” and a thickness of partition wall parts “A”, the relationship 3.1?T/A?6.1 is made to stand by the shaping process. According to this, in a rectangular hole tube, it is possible to change the dimensional relationship of the tube while securing performance so as to improve the endurance to chipping from the front frontal direction to 150 km/h (the conventional endurance being 100 km/h, a ratio to the conventional value of 1.5).

  • Patent number: 6397627
    Abstract: In a receiver-integrated condenser, a super-cooling portion for cooling liquid refrigerant from a receiving unit is disposed between first and second condensing portions in a core portion in a vertical direction. Therefore, in an engine-idling, even when high-temperature air having passed through the receiver-integrated condenser is introduced again toward an upstream air side of the receiver-integrated condenser through a lower side of the receiver-integrated condenser, the high-temperature air is not introduced toward the arrangement position of said super-cooling portion, because the super-cooling portion is positioned at an upper side from the second condensing portion. Thus, super-cooling performance of refrigerant in the super-cooling portion of the core portion is prevented from being decreased even in the engine idling.

  • Patent number: 6374632
    Abstract: In a receiver for separating gas refrigerant and liquid refrigerant and for storing liquid refrigerant for a refrigerant cycle, refrigerant form a condensing portion of a condenser flows into an upper side of a tank member of the receiver from a first refrigerant inlet and flows into a lower side of the tank portion from a second refrigerant inlet. Further, liquid refrigerant stored in the tank member of the receiver is discharged to an outside through a refrigerant outlet. Accordingly, refrigerant from the condensing portion of the condenser flows into the tank portion of the receiver from both upper and lower sides of a gas-liquid boundary surface. As a result, it can prevent the gas-liquid boundary surface of the receiver from being disturbed during a refrigerant introduction of the receiver, while cooling effect of the upper side of the receiver is effectively improved.
