<p>PURPOSE:To reduce the fluctuation of overall torque as well as to eliminate resonant operations between an engine and a compressor by arranging six cylinders at equal intervals on the same circumference passing through the locking section of a piston support, of a circle with center at a driving shaft. CONSTITUTION:When the main shaft 13 of a compressor is driven, both a drive plate 14 and a swash plate 12 are rotated, and a piston support 21 is thereby also rotated. As a result, each piston 31 is reciprocated within each cylinder 33 via each connecting rod 32, therefore, cooling medium is sucked in each cylinder 33 so as to be discharged to a discharge chamber 9 after having been compressed. In this case, six cylinders 33 are arranged at equal intervals on the same circumference passing through the locking section 26 of a piston support 21, of a circle with center at the main shaft 13. Owing to this constitution, the fluctuation of torque generated in each cylinder 33 is mutually composed for reducing the fluctuating amplitude of overall torque. The fluctuation of torque is generated six times per revolution for eliminating resonant operations between an engine and the compressor.</p> |
