Description

[Brief explanation of the drawing]

FIG. 1 is a central vertical sectional view of the silencer of the present invention, and FIG. 2 is a partial longitudinal sectional view taken along line 1-1 in FIG. 1 is an outer cylinder, 2, 3.4 are expansion chambers, 5 and 6 are partition plates, 7 is an exhaust gas introduction pipe, 9: 10 is a coupling pipe, 9A and '10A are exhaust gas inflow side openings, and 11 is a discharge pipe.

Claims (1)

[Scope of utility model registration request] The inside of the outer cylinder is divided into several expansion chambers in the longitudinal direction by a partition plate, and these expansion chambers are sequentially communicated with each other through a connecting pipe, and the exhaust gas introduced into the first chamber from the exhaust introduction pipe is passed through the connecting pipe to the final chamber. In a muffler that allows the exhaust gas to flow into the atmosphere from the exhaust pipe, the effective cross-section required by the joint pipe for exhaust gas circulation is provided between the exhaust gas inflow side opening of the joint pipe and the wall surface of the expansion chamber. A silencer in which the opening is brought close to the wall surface by ensuring an integral gap.
