Abstract

1476233 Piezoelectric igniters BRAUN AG 14 May 1974 [14 May 1973 (2)] 21211/74 Heading H2A In an impact type piezoelectric igniter the piezoelectric transducer has a lateral clearance within the housing of the igniter whereby to achieve good energy transfer when the hammer strikes a bounce place of the transducer. In the igniter shown, an axially magnetized annular magnet 121 is arranged around a mandrel 120 of a bounce plate 108, and exerts a magnetic attraction on the hammer 109 at the time of impaet, thereby to prolong the duration of the impact and of the spark pulse. In the igniter of Fig. 3 (not shown), a permanent magnet (126) and lead core (127) are incorporated in the hammer.
