FIELD: construction.
SUBSTANCE: in a shock absorber of single action, which includes a housing, elastic and damping elements, there additionally contained is an elastic damping destructible element that is attached on support pins to plates-stops by means of a damping base with screws, and a sleeve of single action, which is made from brittle damageable material, for example porcelain, is attached by means of a flange with screws to the damping base coaxially to the pin. The elastic part of the shock absorber is made in the form of at least three plate springs facing with their convex part to the side of the pin axis, on which there is a threaded section with a small pitch for attachment of a clamping element of a sleeve type with grooves for fixation of one of the ends of plate springs, the other end of which is fixed in the damping base by means of cast polyurethane.
EFFECT: improving reliable actuation of explosion-proof devices at emergency explosion at the site.
