Abstract

The object of the invention is an automatic servo-controlled valve with high speed opening wherein the shutter is a hinged cover (20). Suitable locking means (30, 50) keep the cover (20) in a locked position up to the time when the pressure difference on the two faces of the cover exceeds a pre-determined minimum level. After the said locking means have moved to an open position, an actuator (40) operates the opening of the said cover at high speed (FIG. 1).
