  • Detonator for material-dispensing wellbore tools
    Patent number: 8141639
    Abstract: An apparatus for use in dispensing fluid into a wellbore includes a piston element releasably coupled to a housing and a detonator in the housing that applies a force sufficient to release the piston element from the housing when activated. The apparatus also has an intermediate section that mates with the upper section, an elongated member coupled to the piston and that is positioned in a bore of the intermediate section; and a lower section having a housing that mates with the intermediate section. The housing includes at least one opening providing communication between a bore of the housing and an exterior of the housing; and a movable barrier in the lower section. The movable barrier has a first position, wherein the barrier substantially blocks communication between the bore of the intermediate section and the at least one opening, and a second position, wherein the barrier does not substantially block communication between the bore of the intermediate section and the at least one opening.
