It comprises a telescopic assembly formed by a first internal body (1 A) and a second external body (2 A-2 E), the piezoelectric assembly being housed inside and wherein is fixed a piezoelectric crystal which, when struck by the striker hammer (3) appropriately movably guided within the internal telescopic body (1 A), produces the gas lighting spark. The second external telescopic body (2 A-2 E) is closed externally in order to avoid the incoming of foreign elements which could cause problems to the operation of the mechanism. The diametral projections of the striker (3) are actuated by first (25) and second (28) ramps, as well as by longitudinal voids (32) provided in opposite walls of said external telescopic body (2 A-2 E), said ramps guiding the striker (3) both in the assembly process and in the triggering and resetting of said striker. <IMAGE> |
