摘要： A vane type compressor 1 having a drive shaft 2 projecting outward of a housing 5 at a front end and accommodated in the housing 5 at a rear end effectively prevents vanes 4 from generating chattering noise by ensuring biasing of the vanes 4 against an inner peripheral surface of the cylinder 12, for example, in an initial run phase. A high-pressure introduction channel 50 with one end connected to the discharge fluid storage chamber 32 and the other end facing a front end surface of the rotor 3 and configured to communicate with a bottom portion of the vane groove 8 when the distal end of the vane 4 in the corresponding vane groove 8 is in a range from a halfway of the discharge port 16 to the radially sealed section 40 is provided. The high-pressure introduction channel 50 includes a cylinder-side channel 51 formed in the cylinder 12 and communicating with the discharge fluid storage chamber 32 and a side-block-side channel 52 formed in the front side block 21 facing the front end surface of the rotor 3, and the cylinder-side channel 51 and the side-block-side channel 52 communicate with each other via a through hole 59a of a locating pin 59 configured to locate the cylinder 12 and the front side block 21.

摘要： [Object]
To provide a vane compressor in which the structure of the lower end portion of a vane is changed so that the shoulder portions of the lower end portion of the vane have difficulty in overriding on the arc surface on the side of the back pressure chamber and the rotation of the rotor is thereby prevented from being restricted by the vane protruding from the outer peripheral surface of the rotor.
[Solution]
A back pressure chamber 10 having a concave arc surface 101 is formed on the bottom of the vane groove 5, a lower end portion 61 in the forward or backward travel direction of the vane 6 has a convex arc surface 611a facing a bottom side arc surface 101c of the concave arc surface 101 of the bottom of the vane groove 5, and voids D are generated between the lower end portion 61 of the vane 6 and the concave arc surface 101 on the bottom of the vane groove 5 on both sides in the thickness direction of the vane 6 when the lower end portion 61 of the vane 6 makes contact with the bottom side arc surface 101c of the concave arc surface 101 of the bottom of the vane groove 5.

摘要： To provide a vane type compressor that can appropriately keep the allocation of the clearances at the front and rear ends in the axial direction of the rotor by balancing the forces applied to the front and rear sides of the drive shaft. The clearances at the front and rear ends in the axial direction of a rotor 3 are appropriately allocated by providing, in a drive shaft 2, a passage 52 communicating between a low-pressure space 26 communicating with a suction chamber 29 and a shaft end space 15 partitioned by a rear side block 13 and the end of the drive shaft 2 and balancing the forces applied to the front and rear sides of the drive shaft 2. This prevents the compression efficiency from reducing while ensuring the smooth rotation of the rotor 3.
