Explosive actuated valves
Abstract
1. A device of the character described comprising the combination of a generally tubular housing having an end portion forming a chamber to receive the sensitive portion of an explosive squib, a plunger within said housing having an end portion exposed to said chamber, squib retaining means for engaging said housing and a said squib to releasably maintain the squib in close proximity to said plunger end portion including a retaining ring of fusible material spaced outwardly from and encircling at least part of a said squib and part of its sensitive portion for reception of heat from an external source prior to appreciable reception thereof by the sensitive portion of the squib, an annular compression spring bearing at one end against said housing for urging at least a portion of the squib retaining means and a said squib away from said housing and from said plunger end portion upon subjection of the fusible material to heat sufficient to melt at least a portion thereof, and guide means for said spring to maintain even expansion thereof as a said squib is being urged away from said housing.
