  • Publication number: 20080158895
    Abstract: A straddle-type vehicle that reliably inhibits entry of fluid to a tail lamp unit. An extending member protrudes upward from a rear fender and extends in a vehicle width direction. The extending member covers a sealing member of flasher lenses and a tail lamp lens when the motorcycle is viewed from the rear. A gutter guides fluid that enters a space between the extending member and the tail lamp unit.

  • Patent number: 6761106
    Abstract: A compressor includes pistons, each of which is coupled to a swash plate through a pair of shoes. The swash plate rotates integrally with a drive shaft. The shoes convert the rotation of the swash plate to the reciprocation of the piston. A lubricating coating made of copper-based material is formed on parts of the swash plate along which the shoes slide. The copper-based material includes silicon. The shoes smoothly slide on the swash plate, which is coated by the lubricating coating that uses minimum amount of lead.

  • Patent number: 6666128
    Abstract: A swash plate type variable displacement compressor has a housing, a drive shaft, a swash plate and a piston. The housing includes a cylinder block, a front housing, and a rear housing. The drive shaft is rotatably supported by the housing. The swash plate is connected to the drive shaft, and is integrally rotatable with the drive shaft and tiltable relative to the drive shaft. The piston engages with the swash plate through a pair of shoes. Rotation of the drive shaft is converted to reciprocation of the piston through the swash plate and the shoes, and the displacement of the compressor is adjusted by varying the inclination angle of the swash plate with respect to the axis of the drive shaft. The swash plate includes a base member made of copper series and a sliding layer coating a sliding surface of the base member with respect to the shoes.

  • Publication number: 20020046647
    Abstract: Compressors may preferably include a swash plate coupled to a drive shaft, so that the swash plate will rotate in response to rotation of the drive shaft. A piston is preferably disposed within a cylinder bore. A shoe preferably couples the piston to the swash plate, so the piston will reciprocate within the cylinder bore in order to compress a refrigerant in response to rotation of the swash plate. The shoe preferably comprises a main body, a metallic hard layer at least partially disposed on the main body and an anti-friction layer at least partially disposed on the metallic hard layer. The main body preferably comprises a spherical surface portion and a substantially flat surface portion and comprises aluminum. The metallic hard layer preferably has a hardness of at least HV 300 based upon the Vickers hardness scale and is disposed on at least one of the spherical surface portion and the substantially flat surface portion. The anti-friction layer preferably comprises a metal and a solid lubricating agent.
