Abstract: front page image
(EN)Disclosed is a compression device which has a simple structure not requiring safety valves and which is capable of both sealing the inside of a pump, and of releasing internal pressure to the exterior of the pump when the internal pressure within the pump has risen above a predetermined pressure. The compression device is provided with compression elements such as a rotor and a vane within a casing, and with a sealing member (60), which is located within a pump that reaches from a discharge opening in the compression device to an exhaust opening formed in the casing, and which is for sealing the internal pressure within the pump. Further provided is a movable portion (62), which is provided within the sealing member (60) and which elastically deforms so as to release internal pressure to the exterior of the pump when the internal pressure has risen above a predetermined pressure.
(FR)L'invention concerne un dispositif de compression qui a une structure simple ne nécessitant pas de soupapes de sûreté et qui peut étanchéifier l'intérieur d'une pompe et libérer la pression interne vers l'extérieur de la pompe, lorsque la pression interne dans la pompe dépasse une pression prédéterminée. Le dispositif de compression comprend des éléments de compression, tels qu'un rotor et une aube dans un boîtier, et un élément d'étanchéification (60) qui est situé dans une pompe partant d'une ouverture de décharge dans le dispositif de compression jusqu'à une ouverture d'échappement formée dans le boîtier et qui permet de contenir de manière étanche la pression interne dans la pompe. En outre, un élément mobile (62) se trouve dans l'élément d'étanchéification (60) et se déforme élastiquement pour libérer la pression interne vers l'extérieur de la pompe, lorsque la pression interne dépasse une pression prédéterminée.
