Abstract
A rotating cylinder type compressor includes: a cylinder having a cylindrical shape and rotating about a central axis; a first rotor and a second rotor each having a cylindrical shape and rotating about an eccentric axis eccentric to the central axis of the cylinder; a shaft; a first vane; and a second vane. The first vane is slidably fitted to a first groove portion defined in the first rotor to define a first compression chamber. The second vane is slidably fitted to a second groove portion defined in the second rotor to define a second compression chamber. The first rotor and the second rotor are arranged in an extending direction of the central axis of the cylinder.
Claims9
A rotating cylinder type compressor comprising:
- a cylinder having a cylindrical shape and rotating about a central axis;
- a first rotor and a second rotor arranged inside the cylinder, each of the first rotor and the second rotor having a cylindrical shape and rotating about an eccentric axis eccentric to the central axis of the cylinder;
- a shaft that rotatably supports the first rotor and the second rotor;
- a first vane slidably fitted to a first groove portion defined in the first rotor and defining a first compression chamber between an outer circumference surface of the first rotor and an inner circumference surface of the cylinder;
- and
- a second vane slidably fitted to a second groove portion defined in the second rotor and defining a second compression chamber between an outer circumference surface of the second rotor and an inner circumference surface of the cylinder, wherein
- the first rotor and the second rotor are arranged in an extending direction of the central axis of the cylinder,
- a shaft side inlet passage is defined inside the shaft to introduce fluid drawn from outside to be compressed into the first compression chamber and the second compression chamber,
- a first shaft side exit hole through which the fluid flows from the shaft side inlet passage to the first compression chamber and a second shaft side exit holes through which the fluid flows from the shaft side inlet passage to the second compression chamber are defined in an outer circumference surface of the shaft, and
- the first compression chamber and the second compression chamber are connected in parallel to a flow of the fluid.
