Abstract

1325914 Piezo-electric generators CHAFFOTEAUX & MAURY 1 Dec 1970 [9 Dec 1969] 57100/70 Heading H2A An igniter comprises a housing 1 enclosing a piezo-electric unit 2 engaged by a spring-loaded hammer 7 having a central bore 15 which receives the enlarged end 12 of a control rod 11 extending out through the housing. The bore 15 has an eccentric enlargement 16 formed with an inturned lip 17 which hooks behind a conical enlargement 13 on the control rod. On withdrawal of the control rod against a spring 21 the hammer is retracted against spring 18 until one side engages a ramp 8 on the housing which causes the hammer to tilt about the end 12 of the rod until the lip 17 disengages from the enlargement 13 and the hammer is released. The enlargement re-engages automatically with the lip when the control rod is released. The control rod may be actuated indirectly by a push-button or pivoted handle and lever mechanism.
