  • Patent number: 11613158
    Abstract: The present invention relates to an air conditioner for a vehicle, which includes an air-conditioning case (200), and at least one door (100) mounted to be opened and closed at a predetermined position, wherein the door (100) is formed integrally with an arm pivot (140), and the arm pivot (140) includes a pin part, and ribs formed integrally with both sides of the pin part to reinforce rigidity of the pin part and offset noise. The air conditioner further includes distortion preventing parts formed on a rotary shaft to be dented and to be crossed to each other, thereby reducing a transformation rate of the door and securing accuracy of the pin part.
    Type: Grant

  • Patent number: 7507122
    Abstract: A sleeve connector for an electromagnetic clutch has a first holder carrying a diode and a resistor for absorbing surge voltage and removing an induced magnetic field generated by an electromagnetic clutch field coil assembly. First and second terminals respectively connected with the diode and the resistor are held by a second holder so the terminals are insulated from each other. A molded plastic middle assembly encapsulates the diode, resistor, both holders and both terminals and joins the holders to each other.

  • Publication number: 20080105511
    Abstract: The present invention relates to a sleeve connector for an electromagnetic clutch with a diode and a resistor for removing surge voltage and induced magnetic field generated from an electromagnetic clutch field coil assembly. According to the sleeve connector for an electromagnetic clutch of the present invention, an epoxy molding process that increases fabricating cost can be omitted, and also since the sleeve connector uses a holder for fixing each parts, it is prevented that each of the parts is deviated from its position during the plastic molding process.

  • Publication number: 20080073175
    Abstract: In a power transmission apparatus for a compressor according to the present invention, a package of the compressor is reduced in size by shortening the longitudinal length of a one-way bearing while a predetermined level of transmission torque is sustained by optimizing the locations of the one-way bearing and a ball bearing module. Therefore, the mountability thereof can be improved. Also, the one-way bearing is disposed at an outer side from the ball bearing module in a radial direction so as to increase the number of rollers constituting the one-way bearing. Therefore, the transmission torque can be kept identically to that of the related art although the length of the one-way bearing is shortened.
