Title (EN) VANE COMPRESSOR
(FR) COMPRESSEUR À PALETTES
(JA) ベーン型圧縮機
Abstract:
(EN) [Problem] The present invention provides a vane compressor equipped with vanes structured so as to be able to effectively avoid abnormal pressure increases in back pressure chambers of the vanes due to the compression of liquid accumulated in the back pressure chambers. [Solution] In the present invention, vanes are slidably inserted into each of a plurality of vane grooves 7 formed in a rotor 6 that defines a compression space between the rotor and the inner peripheral surface of a cylinder 3a, and the tips of said vanes are pressed against the inner peripheral surface of the cylinder 3a by the pressure in back pressure chambers 70 positioned at the bottoms of the vane grooves 7. A recessed structure for expanding the volume of back pressure chambers 70 are formed in vane bottom surfaces 80 that face the back pressure chambers 70.
(FR) L’invention concerne un compresseur à palettes, lequel est équipé de palettes dont la structure permet d’éviter efficacement une augmentation anormale de pression dans la chambre de contre-pression, cette augmentation étant due à la compression de liquide accumulé dans la chambre de contre-pression. Selon l’invention, des palettes sont introduites de façon coulissante dans chacune des fentes (7) formées dans un rotor (6) qui définit un espace de compression entre le rotor et la surface périphérique interne d’un cylindre (3a). L’extrémité de ces palettes appuie contre la surface périphérique interne du cylindre (3a) à cause de la pression dans les chambres (70) de contre-pression situées au fond des fentes (7). Une structure en retrait permettant d’augmenter le volume des chambres (70) de contre-pression est formée dans les surfaces inférieures (80) des palettes, ces surfaces inférieures étant opposées aux chambres (70) de contre-pression.
(JA) 【課題】 本発明は、ベーンの背圧室に溜まった液体を圧縮することによる背圧室の異常な圧力上昇を効果的に避けることが可能な構造を有するベーンを具備したベーン型圧縮機を提供する。 【解決手段】 本発明は、シリンダ部3a内周面との間に圧縮空間を画成するロータ6に形成された複数のベーン溝7にそれぞれ摺動自在に挿通され、ベーン溝7の底部に位置する背圧室70の圧力によって先端部が前記シリンダ部2内周面に押圧され、前記背圧室70と対峙するベーン底面部80に、前記背圧室70の容積を拡大するための凹み構造が形成されることものである。
