Abstract
A check-valve mechanism of a pulse combustion apparatus for passing air into a mixing chamber includes (i) a partition wall separating an air inlet chamber and the mixing chamber from each other, (ii) a plurality of rear discs of relatively small diameters spaced apart from the partition wall and located inside the mixing chamber, and (iii) a plurality of front discs, or valve members, located between said partition wall and said rear discs; respectively. The circular portions of the partition wall which overlies the respective valve members (as viewed from the side of the air inlet chamber) each have a plurality of radially-extended elongate openings for passing air into the mixing chamber. Each rear disc has a plurality of small circular openings. Each valve member is axially movable between the partition wall and the associated rear disc, thereby opening and closing the elongate openings. A check-valve mechanism for passing fuel gas into a gas distributing chamber includes (i) an outlet-side wall of a fuel gas intlet chamber, (ii) a rear disc spaced apart from the outlet-side wall in a downstream direction and located outside the gas inlet chamber, and (iii) a front disc, or val…
