SILENCER Russian patent published in 2015 - IPC F01N13/18 F01N1/00 

FIELD: engines and pumps.

SUBSTANCE: invention relates to the silencer of the spent gases exhaust system of the internal combustion engine (ICE). Invention means: silencer for system (2) of spent gases exhaust of ICE, in particular mechanical transportation mean, contains the silencer casing (3), that encloses the internal cavity (5) of the casing, at least one located in the internal cavity (5) of the casing and transporting the spent gases hollow element (4) of half-shell design. Both half-shells (14, 15) of the hollow element (4) are secured on each other in area of the separating plane (16). Both half-shells (14, 15) are secured on each other by fastening elements (17, 18), that are made directly in the half-shells (14, 15). Both half-shells (14, 15) in area of the separating plane (16) on sides (19, 20) at distance from each other, respectively, have projecting outside flanging (21, 22), on it the fastening elements are made (17, 18). Both half-shells (14, 15) are adjacent to each other and are secured on each other on this flanging (21, 22). At least one flanging (21) have the strap (26) at distance from the separating plane, it is used as the fastening element (17) and passes parallel to the separating plane (16) in longitudinal direction (27) of the appropriate flanging (21), at that encloses the appropriate flanging (22) of the another half-shell (15) at its area (28) used as complementary fastening element (18). The appropriate flanging (22) of the other half-shell (15) has at least one break (29), through it during assemblage of the hollow element (4) the strap (26) can be inserted transversely to the longitudinal direction of the flanging (22). This break (29) is opened at side on the external surface looking from the gases conducting internal cavity of the hollow element (4).

EFFECT: assurance of easy assemblage of the structure, and economy manufacturing.
