Claim 0:
1. A single-stage enthalpy enhancing rotary compressor, comprising at least one single-stage cylinder, a rotator, an upper flange, and a lower flange, wherein:
the rotator is arranged inside the cylinder and is rotatable;
a compression chamber is formed between the rotator and an inner peripheral wall of the cylinder;
a vapor injection opening is defined in at least one of the upper flange and the lower flange, and the vapor injection opening is configured to supply gas outside the compressor to the compression chamber directly;
the cylinder is provided with a sliding vane slot;
a rotation angle of the rotator is calculated from 0°, defined by a position where a sliding vane fully extends into the sliding vane slot;
the vapor injection opening is configured: during a movement of the rotor in one circle, when the rotator rotates to a first preset position range of 135° to 345°, not to be blocked by the rotator, and configured to be automatically opened to open a vapor injection; and
the vapor injection opening is further configured: during the movement of the rotor in the one circle, when the rotator rotates to a second preset position range of −15° to 135°, to be blocked by the rotator and to be automatically closed to close the vapor injection;
wherein a complete cycle of the compressor is performed within the first preset position range and the second preset position range.
