Kind Code:
A1
Abstract:
A rotary compressor, comprising: a cylinder (1) provided with a sliding vane groove (12); a sliding vane (3) installed in the sliding vane groove (12); a cam mechanism (2), a cam part of which is rotatably provided in the cylinder (1); and a sliding shoe (4) pressed against an outer circular surface of the cam part, wherein the sliding vane (3) is provided with an arc-shaped opening groove (5), the sliding shoe (4) comprises an arc-shaped hinge joint, the hinge joint is hinged with the opening groove (5), the sliding shoe (4) is connected to the hinge joint by means of a neck part, and the width of the neck part is smaller than the width of the hinge joint; or the sliding shoe (4) is provided with the arc-shaped opening groove (5), the sliding vane (3) comprises the arc-shaped hinge joint, the hinge joint is hinged with the opening groove (5), the sliding vane (3) is connected to the hinge joint by means of the neck part, and the width of the neck part is smaller than the width of the hinge joint. And a gas compression system, a refrigeration system and a heat pump system comprising the rotary compressor. Such a rotary compressor reduces the friction between the sliding vane and a friction pair of the cam part, and improves system reliability.
