摘要： The invention relates to a firing mechanism for high acceleration applicans having a body member having a first chamber, a second chamber and a web member separating the first chamber from the second chamber. A first spring is positioned within the first chamber and a second spring is positioned with the second chamber. A firing pin is positioned substantially in the first chamber and has a spring retaining section at its forward end and a release cam mechanism at its rearward end. An arming pin is positioned substantially in the second chamber and has a spring retaining section at its rearward end and a release cam mechanism at its forward end. The release cam mechanism of said arming pin is dimensioned to interlock with said release cam mechanism of the firing pin with the two release cam mechanism and is positioned within the web member and is restrained against release by the web member. The firing pin and the arming pin are movable together in the rearward direction to a position in which the interlocked release cam mechanisms are outside of the web member and free to separate.
