Abstract

An improved safety-valve capable of being changed over from the service position to the safety position by a blow or pressure on the valve cap and comprising a seating, a shut-off member with a closure position applied against said seating and an opening position spaced apart from said seating, a spring urging said shut-off member towards the safety position, a first means for bringing the shut-off member into the service position against the action of said spring and being capable of being put out of action a second means, including a retractable retaining bolt, substituted for said first means in holding said valve in the service position when said first means is out of action, and means for instantaneously removing said bolt in case of urgency, whereby said shut-off member moves immediately into the safety position.
