Patent number: 6532655Abstract: A method of manufacturing a hollow piston for variable displacement swash plate compressors of air conditioning systems is disclosed. This method produces a desired hollow piston by separately forming a body and a cap and by simply machining the body and the cap prior to simply welding the body and the cap together into a single structure through a frictional welding process. This method thus remarkably simplifies the pre-welding machining process. In the frictional welding process, the body and the cap are welded together into a single structure by simply and relatively rotating the body and the cap while forcing them toward each other under atmospheric air at room temperature. The frictional welding process is thus accomplished using a simple welding machine, thereby reducing the equipment cost while producing the hollow pistons. The frictional welding process is also free from oxidizing the welded portions of a resulting hollow piston, and so the resulting piston does not have micro pores in its structure.Type: GrantFiled: December 17, 1999Date of Patent: March 18, 2003Assignee: Halla Climate Control Corp.Inventors: Hew Nam Ahn, Young Seop Yoon

Patent number: 6488454Abstract: A method for machining a pair of shoe pockets for piston in a swash plate type compressor is disclosed. In this method, the shoe pockets are respectively formed on the opposed walls of the slot in the piston of the compressor while conforming to a single imaginary sphere. The method comprises the step of moving a cutter provided with an arc-shaped cutter blade that has a rotation diameter less than the width of the slot. Thereafter, there is performed the step of relatively revolving the cutter with regard to the piston by allowing the central axis of a revolved part to move along a circular orbit within the slot while rotating the cutter, so as to cut the shoe pockets to conform to the single imaginary sphere. Finally, the step of retreating the cutter out of the slot when the cutter completes one round revolution and is returned to its initial position is performed.Type: GrantFiled: September 6, 2000Date of Patent: December 3, 2002Assignee: Halla Climate Control Corp.Inventors: Hew Nam Ahn, Young-seop Yoon
