Abstract
A rotary compressor (102) has a shaft (4), a cylinder (5), a piston (8), a first vane (32), and a second vane (33). The first vane (32) divides a space between the cylinder (5) and the piston (8) along a circumferential direction of the piston (8). The second vane (33) further divides the space divided by the first vane (32) along the circumferential direction of the piston (8) so that a first compression chamber (25) and a second compression chamber (26) having a smaller volume than the first compression chamber (25) are formed within the cylinder (5). The piston (8) and the second vane (33) are integrated together, or the piston (8) and the second vane (33) are coupled together.
Claims14
A rotary compressor comprising:
- a cylinder;
- a piston disposed within the cylinder so as to form a space between the piston itself and the cylinder;
- a shaft to which the piston is fitted;
- a first vane for dividing the space along a circumferential direction of the piston, the first vane being attached to the cylinder at a first angular position along a rotation direction of the shaft;
- and
- a second vane for further dividing the space divided by the first vane along the circumferential direction of the piston so that a first compression chamber and a second compression chamber having a smaller volume than the first compression chamber are formed within the cylinder, the second vane being attached to the cylinder at a second angular position along the rotation direction of the shaft,
- wherein the piston and the second vane are integrated together, or the piston and the second vane are coupled together.
