摘要： PROBLEM TO BE SOLVED: To provide a rotary compressor device that reliably reduces sliding loss generated on an eccentric part of a crankshaft and on an inner circumference of a roller, and has superior reliability and durability.
SOLUTION: The rotary compressor device is stored in a sealed container 1 where an electric motor 2 is connected to a compression mechanism 3 by the crankshaft 31. The compression mechanism 3 includes: a cylinder 30; a compression chamber 39 which is formed by an upper bearing 34 and a lower bearing 35 blocking both end faces of the cylinder 30; the roller 32 which is fitted to the eccentric part 31a of the crankshaft 31 installed in the cylinder 30; and a vane 33 which follows an eccentric rotation of the roller 32 and reciprocates in a slot provided in the cylinder 30, thereby separating the compression chamber 39 into a low and high pressure parts. In the device, a relief 42 is established on the eccentric part 31a in a tilting direction during an operation of the crankshaft 31.

摘要： PROBLEM TO BE SOLVED: To provide a swing-type expander reduced in sliding loss in a bearing.
SOLUTION: The swing-type expander 100 includes a cylinder 15, a shaft 13, a piston 19, a vane 21, and the bearing 17. The piston 19 is attached to the shaft 13 to be rotated in the cylinder 15. The vane 21 is formed integrally with the piston 19, swingingly held in a groove 15d formed at the cylinder 15, and partitions a space between the cylinder 15 and the piston 19 into a suction space 25a and a delivery space 25b. The position of the vane 21 in the peripheral direction of the shaft 13 is defined as a reference position. The bearing surface of the bearing 17 is formed with a recessed portion 130 in a range of 90-180° in the rotating direction of the shaft 13 when viewed from the reference position.

摘要： PROBLEM TO BE SOLVED: To provide a hermetic compressor improved in performance and reliability by preventing the increase in bearing load by centrifugal force acting on a weight.
SOLUTION: The compressor includes a thrust ball bearing disposed between a thrust surface of a main bearing 126 and a flange part 121. The flange part 121 includes a weight 172 in a position vertically below the lower end surface contacting with the thrust ball bearing, the position being symmetric to an eccentric shaft part 122 in axial projection of a main shaft part 120. Since the bearing load by centrifugal force acting on the weight 172 is never increased, efficiency and reliability are improved.
