Title
(EN) SINGLE-SCREW COMPRESSOR
(FR) COMPRESSEUR MONOVIS
(JA) シングルスクリュー圧縮機
Abstract
(EN)
The disclosed single-screw compressor (1) includes: a screw rotor (40); a casing (30) having a cylinder wall (31) which rotatably encloses the screw rotor (40); a drive mechanism (26) which drives the screw rotor (40) in such a manner that the operation capacity can be varied depending on the load; and a slide valve (4) which is provided so as to face the outer peripheral surface of the screw rotor (40) and to be movable in the axial direction in a slide groove (33) formed in the cylinder wall (31), and which adjusts the discharge start position by moving in the axial direction depending on the operation capacity. The discharge-side end face (4a) of the slide valve (4) is formed so as to extend in the direction corresponding to a screw land (42) that the slide valve opposes when located at a slide position taken during partial load operation.
(FR)
L'invention concerne un compresseur monovis (1) qui comprend: un rotor (40) en forme de vis; une enveloppe (30) comportant une paroi (31) de cylindre qui enveloppe de manière rotative ledit rotor (40); un mécanisme (26) d'entraînement qui entraîne le rotor (40) en forme de vis de manière à permettre une variation de la capacité de fonctionnement selon la charge; et un tiroir (4), prévu face à la surface périphérique extérieure du rotor (40) en forme de vis et qui peut être déplacé dans la direction axiale dans une rainure (33) de tiroir formée dans la paroi (31) du cylindre, et règle la position de départ de refoulement en se déplaçant dans la direction axiale selon la capacité de fonctionnement. La face d'extrémité (4a), du côté refoulement du tiroir (4), est formée de manière à se déployer dans la direction correspondant à une zone (42) de vis se situant à l'opposé du tiroir quand ce dernier est dans une position coulissante, pendant un fonctionnement à charge partielle.

 シングルスクリュー圧縮機(1)は、スクリューロータ(40)と、該スクリューロータ(40)を回転可能に収納するシリンダ壁(31)を備えたケーシング(30)と、スクリューロータ(40)を負荷に応じて運転容量可変に駆動する駆動機構(26)と、シリンダ壁(31)に形成されたスライド溝(33)においてスクリューロータ(40)の外周面に対向すると共に軸方向に移動可能に設けられ、運転容量に応じて軸方向に移動して吐出開始位置を調整するスライドバルブ(4)とを備えている。上記スライドバルブ(4)の吐出側端面(4a)を、部分負荷の運転状態におけるスライド位置において対向するスクリューランド(42)に対応した方向に延びるように形成する。
