ABSTRACT:
Of the type that include two telescopic bodies (1, 2) aided by a spring (17) which keeps them extended, there being inside the former the piezoelectric element (3) immobilized between an anvil (4) and the stop piece (6) upon which a firing hammer (8) strikes generating the spark.
The outside telescopic body (2) includes a pair of ribs (22) which emerge from diametrically opposite points of the cylindric surface of its axial recess, which guide the telescopic displacement of the other body (1) upon introducing themselves in respective longitudinal grooves (12) of the body, in which the diametric projections (10) of the guide of the firing hammer (8) play.
The body (2) has in its end opposite the emergence of the body (1) with a widened axial recess where there is a pair of confronting windows in which a cover (14) is secured in which springs (13, 17) which aid the firing hammer and telescopic body (1) are included.
