In the present invention, there is disclosed a vane rotation type fluid device comprising a compression element (12) or an expansion element for compression or expansion of coolant, and an electrically controlled element (15) for driving the compression element (12) or the expansion element within a sealed container. The compression or expansion element (12) comprising means for controlling the position of a vane (8) is arranged along internal peripheral surface of a cylinder (5). The control means have a ring-shaped groove (17) that is arranged in at least one of two bearings (3, 4) and is performed co-axially with the cylinder (5) internal peripheral surface, and a ring (9), which is slidably mounted in the ring-shaped groove (17) and is connected with the vane (8) end. The position control means also have at least one opening (8a, 9a) for a pin (10), performed in at least one vane (8) and in the ring (9), a cylindrical pin (10), inserted in the pin opening (8a, 9a), wherein the vane (8) is rotatably mounted relative to the ring-shaped groove (17). The vane (8), having a rounded-off end, and the pin (10) are situated so that the center of the rounded-off end of the vane (8) is identical with the center of the pin (10). |
