Title (EN) FLUID MACHINE
(FR) MACHINE HYDRAULIQUE
(JA) 流体機械
Abstract:
(EN) Provided is a fluid machine configured such that liquid supplied to an operating space from the outside of the fluid machine is dispersed extensively in the operating space. This fluid machine is constituted of a screw rotor and a casing for accommodating the screw rotor and is provided with a liquid supply section for supplying liquid into an operating space from the outside. The liquid supply section is configured so that liquid is dispersed in the longitudinal direction of the tooth groove of the screw rotor rather than in the width direction thereof.
(FR) L'invention concerne une machine hydraulique conçue de telle sorte que le liquide fourni à un espace de fonctionnement depuis l'extérieur de la machine hydraulique soit dispersé de manière extensive dans l'espace de fonctionnement. La machine hydraulique selon l'invention est constituée d'un rotor à vis et d'un boîtier pour recevoir le rotor à vis et est pourvue d'une section d'alimentation en liquide pour fournir un liquide dans un espace de fonctionnement depuis l'extérieur. La section d'alimentation en liquide est conçue de sorte que le liquide soit dispersé dans la direction longitudinale de la rainure de dent du rotor à vis plutôt que dans la direction de la largeur de celle-ci.
(JA) 流体機械の外部から作動空間に供給された液体を、作動空間の広範囲に拡散させる。スクリューロータと、前記スクリューロータを収納するケーシングによって構成され、作動空間内に外部から液体を供給する液体供給部を備える流体機械であって、前記液体供給部は、前記スクリューロータの歯溝の幅方向よりも長手方向に液体を拡散するように構成したものである。
