  • Patent number: 6814138
    Abstract: An air conditioning apparatus for an automotive vehicle includes a case having an opening which is formed at a side wall of the case. A heater core is installed in the case; and a mix door assembly detachably is installed in said case through the opening. The mix door assembly is adapted to vary a ratio of quantity of air passing through said heater core to a quantity of air bypassing said heater core. The mix door assembly including a housing, a mix door installed in the housing, and a slide mechanism installed in the housing. The slide mechanism is adapted to receive a rotational force and slide the mix door with respect to the housing according to the received rotational force to vary the ratio.

  • Publication number: 20030218332
    Abstract: The present invention provides a joint (50) preferably applied to a double pipe (100) and a brazing method thereof. The double pipe (100) is provided with an outer pipe (101), an inner pipe (102) and connection ribs (103) integrally formed. The joint (50) is provided with a first junction portion (510) having a stopper (511) and a through hole (541) having a support portion(523). When brazing the double pipe (100) with the joint (50), the support portion is faced upward so that molten brazing metal is supported therein.

  • Patent number: 6520074
    Abstract: An improved pressing machine for forming a work (21) being progressively or sequentially fed along a coil line, having a press assembly (1) that comprises a plurality of modular press units (11, 12, 13, . . . ) connected from one to another in a direction in which the work (21) is progressively fed. Each of the press units (11, 12, 13, . . . ) includes a C-form frame (2), a slide drive mechanism (6) disposed in an upper part of the C-form frame (2) and having in its drive source (7) a servo motor means operable under NC, and a slide (5) adapted to be driven by the slide drive mechanism to move in a given movement pattern. The press units (11, 12, 13, . . . ) having their respective slides (5), at least some of which have at least one slide adapter plate (19) attached thereto, the at least one slide adapter plate extending across those at least some of the slides as a whole.

  • Patent number: 4867648
    Abstract: A wobble plate type compressor is equipped with a device which can be selectively activated in a manner to induce the wobble plate to assume a position wherein the displacement of the compressor is reduced to zero and thus obviate the need for a clutch for such purposes. The device further includes an arrangement which biases the wobble plate toward a position wherein a positive displacement of the compressor will occur when in a non-activated state. The strength of this bias is insufficient to interfere with the control of the wobble plate inclination by the pressure prevailing in the chamber in which the plate is disposed.

  • Patent number: 4860549
    Abstract: The discharge of a variable displacement wobble plate compressor is varied by selectively controlling the pressure prevailing in the crankcase of the device. The duty cycle of a signal controlling the pressure is determined in accordance with the ambient air temperature, the temperature required in the cabin and pressure prevailing in the evaporator.

  • Patent number: 4708598
    Abstract: A rotary vane-type gas compressor for use in car coolers and the like has a plurality of intake ports for each compression working chamber located at positions shifted from one another in the revolving direction of a rotor. At least one intake port which is located at the most forward position in the revolving direction of the rotor has a throttle valve which is controlled in response to the flow rate of suctioned gas, and the opening degree of the throttle valve is changed as the revolution speed of the rotor increases and creates a higher flow rate of suctioned gas. This reduces the effective compression working chamber volume, i.e., the volume which results when one vane has passed the position of the corresponding intake port to enclose gas in the compression working chamber. By such a construction, it is possible to restrain a substantial increase in both the amount of compressed gas to be discharged and the air-cooling capacity, even when the revolution speed of the rotor increases above 2000 rpm.
