摘要： An axially elongated member is provided with an antechamber at one end thereof for receivably engaging the firing end of a spark ignition device. The axially elongated member includes a diverging-converging exit nozzle in its other end and a narrow bore or port extending between and connecting the antechamber with the exit nozzle. The nozzle''s exit aperture is formed in the end face of the member and thus defines an annular baffle means axially displaced from the point where the narrow bore opens into the exit nozzle. Because of its diverging-converging construction the interior recess of the nozzle is enlarged with respect to the diameter of its exit aperture which latter, in turn, is enlarged with respect to the diameter of the narrow bore or port. The axial member further includes means for preventing a fluid flowing along a wall surface perpendicular to the axis thereof from flowing over the end face of its other end and entering the enlarged interior recess of the exit nozzle.
