Abstract
In a pulse combustion device including a housing forming therein a combustion chamber, a cylindrical support member joined to the housing to form a mixing chamber in open communication with the combustion chamber, an annular perforated flange member coupled with an open end of the support member, a cylindrical member mounted in the center of the flange member to form a gas passage in open communication with the mixing chamber, a flapper-type air inlet valve assembly mounted on the flange member, and a flapper-type gas inlet valve assembly disposed within the cylindrical member. The air inlet valve assembly includes an annular valve plate formed with a plurality of circumferentially equi-spaced circular air ports and being secured to annular end surfaces of the flange member and the cylindrical member, and a plurality of circumferentially equi-spaced air inlet valve units mounted on the valve plate on a common circular path concentric with the gas passage. The air inlet valve units each includes a circular perforated backer plate arranged within the mixing chamber to oppose each of the air ports and fixed to the valve plate through a spacer, and a circular air flapper movable between the valve plate and the backer plate.
