Latest Patents

Hiroshi Koga holds a patent for a swash plate type compressor featuring a center cavity in the surface of the piston. This design includes shoes with center holes on their slidable surfaces. The center hole, which has a bottom, serves as a reservoir for lubricating oil, supplying it to the slidable surface of the shoe that interacts with the swash plate. Additionally, the design allows for a second ring groove concentric to the center hole or annexed grooves that extend radially outward. This innovative feature also prevents the center part from protruding outward due to thermal expansion caused by friction. The slidable surface of the shoe is ideally coated with a layer containing solid lubricant to facilitate smooth sliding motions.
