Abstract
1473629 Piezoelectric igniters CONSTRUCTIONS ELECTRIQUES RV 7 May 1975 [9 May 1974] 19200/75 Heading H2A In a piezoelectric igniter, a spring blade 17 has a base portion 21 mounted on an anvil 3 of a piezoelectric element 1, and has a portion 19 which initially retains a hammer 10 in position as a button 9 is pushed into a casing 8 of the igniter, but when the button approaches the end of its travel the portion 19 of the blade 17 is deflected, e.g. when it engages ramps or ascending grooves 20 in the button 9, and a compressed spring 11 is released to propel the hammer 10 on to the anvil 3. In the arrangement shown, the casing 8 is metallic and the element 1 is mounted in an insulating body 2, and makes contact with the casing 8 via the anvil 3, the blade portion 21, and a pressure plate 25 held by casing indentations (29, Fig. 4, not shown). In an alternative arrangement (Fig. 8, not shown), a corresponding spring blade member is of U-shape, and has two retaining portions (17, 17<SP>1</SP>).
