Normally closed valve structure is located in a fluid path between the suction and discharge sides of a compressor. The valve structure opens upon a small pressuredifferential when the higher pressure is in the normal suction side which is indicative of reverse operation. Additionally, relief valve structure opens when the discharge pressure becomes excessive.
La présente invention vise une vanne normalement fermée disposée sur la trajectoire d'un fluide entre le coté aspiration et le côté évacuation d'un compresseur. La vanne s'ouvre en présence d'un faible différentiel de pression lorsque la pression la plus élevée est décelée du côté nominal d'aspiration, ce qui correspond à un fonctionnement inversé. La vanne de sûreté s'ouvre également lorsque la pression d'évacuation est trop élevée.
