Abstract:
1. A guard fixed to a gas cylinder actuator, said guard comprising a covering element that is constituted by a monolithic dome, said monolithic dome being fixed to a stem of the gas cylinder actuator, said monolithic dome being contoured so as to extend radially from a fixing region between the monolithic dome and the stem in order to protect the stem and an opening of a body of the actuator from which said stem slidingly exits along an axial sliding direction, said monolithic dome being made of plastic material, and the monolithic dome comprising an annular cover which surrounds the stem that enters a central hole of said annular cover such that the monolithic dome is keyed at an end of the stem of the gas cylinder actuator, wherein said central hole being keyed in an annular slot provided on said end of said stem such that the monolithic dome keyed by interference on said stem, and the monolithic dome further comprising a substantially cylindrical tubular body extending from said annular cover and slidingly connected together with the stem with respect to the body of the actuator, and said tubular body being shaped so as to directly cover at least part of the body of the actuator both when the stem is completely extended from said body and when the stem is completely retracted into said body, said monolithic dome, which includes said annular cover together with said tubular body extending from said annular cover, being shaped such that it is substantially impossible for fluid falling from above said actuator with respect to said axial sliding direction to reach said opening of said body from which said stem slidingly exits to protect the stem and the opening of the body of the actuator from which the stem slidingly exits.
