Piston type compressors |
摘要 |
A piston for use in a compressor is disclosed. The piston has a head for compressing gas and a skirt connected to a swash plate. A first seal and a second seal, which always contact a cylinder bore, are defined on the head. An annular groove is formed between the first and second seals. Lateral forces acting on the piston are received by the first and second seals. A space is formed in the piston to open to the side of the piston between the second seal and the skirt. This reduces the weight of the piston and stabilizes the movement of the piston.
