Swash plate type compressor

摘要

A swash plate type compressor adapted for use in an automotive cooling system is disclosed. A cylinder block, which forms a principal part of the compressor and is axially divided into two portions, has at least four bores arranged at equal distances along the circumference thereof. A clamping bolt for uniting all principal members of the compressor extends through a hole provided through a narrow interzone lying between each two adjacent bores. The through hole has a diameter considerably greater than that of the clamping bolt. The space between the inner surface of the hole and the outer surface of the bolt serves as a passage through which a low pressure refrigerant gas flows, and this helps simplification in construction and improvement in capacity of the swash plate type compressor.
