Title:
COMPRESSOR
Document Type and Number:
Japanese Patent JP2020105984
Kind Code:
A
Abstract:
To provide a compressor capable of suitably suppressing the positional deviation of a body of rotation from a fixed body.SOLUTION: A compressor 10 includes a rotary shaft 12, a body of rotation 60 adapted to be rotated in association with the rotation of the rotary shaft 12, and fixed bodies 90, 110 adapted not to be rotated in association with the rotary shaft 12, the body of rotation 60 having body-of-rotation surfaces 71, 72, the fixed bodies 90, 110 having fixed body surfaces 100, 120 opposed to the body-of-rotation surfaces 71, 72 in an axial direction Z, respectively. Herein, the compressor 10 further includes a vane 131 inserted into a vane groove formed in the body of rotation 60, and compression chambers A4, A5 defined using the body-of-rotation surfaces 71, 72 and the fixed body surfaces 100, 120. The vane 131 is rotated while moving in the axial direction Z in association with the rotation of the body of rotation 60. In the compression chambers A4, A5 where volume changes are caused by the vane 131, the suction/compression of fluid is carried out.SELECTED DRAWING: Figure 1
