<p>PROBLEM TO BE SOLVED: To make a compressor lighter, and prevent noise and sliding contact abrasion. SOLUTION: A piston 8 has a connecting part 8b in the central part of an intermediate part from the opened edge of a cylinder bore 1a to the head of the piston 8 at a bottom dead center position A, and moreover the first lightened part 8c formed on the whole periphery of the piston 8, and a sliding contact part form the opened edge of the cylinder bore 1a when the piton is at the bottom dead center position A to the opened edge of the cylinder bore 1a when a piston 9 is at the top dead center position B of a piston 9, and the sliding part is provided with the second lightened part 8j which is larger than the half circle of the piston 8 and made hollow toward the central axis of a swash plate.</p> |
