<p>PURPOSE:To sufficiently lubricate a surface of a swash plate at start of a compressor by providing a sub-oil sump at the lower part of a swash plate for dipping the lower part of the swash plate in an oil deposited therein at stop of the compressor and feeding back an oil deposited in auxiliary oil chambers during operation of the compressor into the sub-oil sump while the compressor rests. CONSTITUTION:A sub-oil sump chamber 21 is provided at the lower part of a swash plate 13, that is, between mutually adjacent two bores of left and right cylinder blocks 2, 3, constituted in such a manner that the lower part of the swash plate 13 with an oil deposited therein is dipped while a compressor rests. A part of the oil floating in the state of mist in the sub-oil sump chamber 21 passes through communication holes 29, 30 into auxiliary oil chambers 25, 26 disposed around the sub-oil sump chamber 21 and is gradually concentrated and deposited therein. When the compressor stops, no oil enters the auxiliary oil chambers 25, 26 through the communication holes 29, 30 from the sub-oil sump 21 and the oil in the auxiliary oil chambers 25, 26 goes slow into the sub-oil sump 21 through small openings 27, 28. As sufficient oil in the sub-oil sump chamber 21 is ensured at start of the compressor, the surface of the swash plate may be well lubricated.</p> |
