Abstract
A compressor includes two rotors opposed to each other in an axial direction, and a vane contacting the rotors. While the vane is moved in the axial direction with rotation of the rotors, the vane is restricted from rotating by a vane groove. The compressor includes compression chambers in which suction and compression of fluid are performed with rotation of the rotors, and a communication mechanism switched between a communicating state in which the compression chambers communicate with each other, and a non-communicating state in which the compression chambers do not communicate with each other.
Claims6
A compressor comprising:
- a rotary shaft;
- a first rotor including a ring-shaped first rotor surface, and rotated with rotation of the rotary shaft;
- a second rotor opposed to the first rotor in an axial direction of the rotary shaft, rotated with the rotation of the rotary shaft, and including a ring-shaped second rotor surface;
- a first cylindrical portion including a first inner circumferential surface opposed to an outer circumferential surface of the first rotor in a radial direction of the rotary shaft, and housing the first rotor;
- a second cylindrical portion including a second inner circumferential surface opposed to an outer circumferential surface of the second rotor in the radial direction, and housing the second rotor;
- a wall portion arranged between the rotors, and including a first wall surface opposed to the first rotor surface in the axial direction, and a second wall surface opposed to the second rotor surface in the axial direction;
- a vane contacting the rotor surfaces in a state where the vane is inserted into a vane groove formed in the wall portion, and moving in the axial direction with rotation of the rotors;
- a first compression chamber formed by the first rotor surface, the first wall surface, and the first inner circumferential surface, a volume change of the first compression chamber being caused by the vane with rotation of the first rotor, such that suction and compression of fluid are performed;
- a second compression chamber formed by the second rotor surface, the second wall surface, and the second inner circumferential surface, a volume change of the second compression chamber being caused by the vane with rotation of the second rotor, such that suction and compression of the fluid are performed;
- and
- a communication mechanism switched between a communicating state in which the first compression chamber and the second compression chamber communicate with each other, and a non-communicating state in which the first compression chamber and the second compression chamber do not communicate with each other.
