Abstract
An electric fuze, especially for hand grenades, having a power source which is activatable by the effect of a force for supplying output power and a delay unit for delaying the ignition of a primer with respect to the time of activation of the power source. The delay unit has a variable time constant and includes an RC circuit formed of a plurality of series or parallel connected resistors and/or capacitors which are functionally connected with one another by electrical leads which leads are arranged to be open-circuited for the purpose of changing the delay time in a predetermined manner.
Claims19
An electric fuze, especially for hand grenades, comprising power source means responsive to a force effect for supplying power output, delay unit means responsive to the power output of said power source means for providing an output for igniting a primer at a time period delayed with respect to the time of supply of power output by said power source means, said delay unit means being an RC circuit means having a variable delay period and including at least a plurality of one of resistors and capacitors connected in one of a series and parallel connection, said plurality of one of resistors and capacitors being electrically connected together by electricl leads disposed to be open-circuited so as to interrupt the electrical connection therethrough for changing the delay period of said delay unit means in a predetermined manner, and means for severing at least one of said electrical leads so as to provide an open circuit thereof thereby changing the delay period.
An electric fuze, especially for hand grenades, comprising power source means responsive to a force effect for supplying power output, delay unit means responsive to the power output of said power source means for providing an output for igniting a primer at a time period delayed with respect to the time of supply of power output by said power source means, said delay unit means being an RC circuit means having a variable delay period and including at least a plurality of one of resistors and capactiors connected in one of a series and parallal connection, said plurality of one of resistors and capacitors being elecrically connected together by electrical leads disposed to be open-circuited so as to interrupt the electrical connection therethrough for changing the delay period of said delay unit means in a predetermined manner, and bipartite housing means for accommodating said RC circuit means therein, said housing means having two parts movable with respect to each other for open circuiting electrical leads associated with respective ones of said plurality of one of resistors and capacitors.
