A compressor structure includes a vane rotor and a cylinder eccentrically disposed around the vane rotor. The vane rotor has a vane impeller. The vane impeller is in tangential contact with the cylinder to define an eccentric crescent vane chamber. A vane is radially slidably received in the vane impeller. An outward extending top end of the vane tightly abuts against the inner circumferential wall of the vane chamber, whereby the vane chamber is partitioned into an intake section and a compression exhaustion section. When the vane rotor rotates, the vane is driven to drive the cylinder to complete gas compression operation. When rotating, the vane is simply swung at a fixed position of the cylinder, the friction of the compressor can be lowered. The communication of the gas outlet is regulated so that the compression ratio of the compressed gas exhausted from the compressor can be changed.
A compressor structure comprising a vane rotor and a cylinder eccentrically disposed around the vane rotor, the vane rotor and the cylinder being rotatable at the same time, the cylinder being pivotally rotatably disposed on a main seat, the vane rotor having a vane impeller, a circumferential wall of the vane impeller being in tangential contact with an inner circumferential wall of the cylinder to define an eccentric crescent vane chamber in the cylinder, a radial vane slot being formed on the circumference wall of the vane impeller, a vane being slidably received in the vane slot, the vane having an outward extending end formed with vane pivotally connecting sections, by means of the vane pivotally connecting sections, the vane being securely pivotally connected on the cylinder, whereby a top end of the vane tightly abuts against the inner circumferential wall of the vane chamber so that the top end of the vane is in an axial sealed contact with the inner circumferential wall of the vane chamber, whereby an interior of the vane chamber is partitioned by the vane into an intake section and a compression exhaustion section, a gas inlet being disposed in the intake section, a gas outlet being disposed in the compression exhaustion section, the gas inlet and the gas outlet being respectively positioned in different axial positions of the cylinder, a circular cylinder receiving chamber being formed on one side of the main seat, which side faces the cylinder, the cylinder receiving chamber serving to receive one end of the cylinder proximal to the gas outlet and block the gas outlet, at least one connection supports being disposed on the main seat for securely assembling with the cylinder, the connection supports providing supporting effect to form at least one hollow section, whereby one end of the gas inlet is exposed to the hollow section without being blocked by the cylinder receiving chamber, the cylinder receiving chamber having a circular inner circumferential wall, an out-guiding hole being formed between the inner circumferential wall and an outer wall of the main seat in communication with inner side and outer side.
