Claims (1)
駆動シヤフトを支承するフロントサイドブロツク
及びリヤサイドブロツクと、両サイドブロツクの
間に介在し吸入側と吐出側とに夫々連通している
圧縮室を形成したカムリングと、該カムリング内
に配設され前記駆動シヤフトに軸支されるロータ
と、該ロータの略半径方向に沿つて出没自在に嵌
装されると共に前記ロータの回転に伴い先端側を
前記圧縮室の内壁に圧接しつつ基端側に背圧室を
形成するように設けられるベーンとを備えて成る
ベーン型圧縮機において、前記各サイドブロツク
のいずれか一方に前記背圧室とを連通して前記ベ
ーンに背圧を付与する背圧連通溝を形成したこと
を特徴とするベーン型圧縮機。 A drive shaft with one end protruding toward the atmosphere, a front side block and a rear side block that support the drive shaft, and a compression chamber interposed between both side blocks that communicates with the suction side and the discharge side, respectively. a cam ring disposed within the cam ring and pivotally supported by the drive shaft; the rotor is fitted so as to be freely protrusive and retractable along a substantially radial direction of the rotor, and the distal end side is compressed as the rotor rotates; In a vane type compressor comprising a vane that is provided so as to form a back pressure chamber on the proximal end side while being in pressure contact with an inner wall of the chamber, either one of the side blocks is communicated with the back pressure chamber. A vane type compressor, characterized in that a back pressure communication groove is formed for applying back pressure to the vane.
