摘要： A suction air filter for a combustion engine includes a filter housing for receiving a filter insert and an attachment housing to which the filter housing is attached. The filter housing has a coupling end for coupling with a corresponding coupling end of the attachment housing. The suction air filter has an unfiltered air intake and a pure air outlet. A plurality of cam members are mounted on the outside of the filter housing near the coupling end thereof, and a plurality of cam elements are mounted on the outside of the attachment housing near the coupling end thereof. A rotatable coupling ring is mounted to receive the coupling ends of the filter housing and the attachment housing, and the coupling ring carries wedge members which are engagable with the cam members and the cam elements to releasably couple together the coupling ends of the housings. Dust protection shoulders or labyrinth seals are provided on both sides of the coupling ring to prevent dust from penetrating in the closure area of the attachment portion and the housing. A turning of the coupling ring effects a fixing of the filter housing to the attachment housing.

摘要： This invention relates to a silencer for muffling the flow of exhaust gases from an engine before they enter the atmosphere. This silencer comprises a tubular housing having an absorption section with an inlet and an outlet opening. The absorption section is constructed of three walls: and outside wall, a middle wall and a perforated inside wall. Positioned between the middle and outside wall is a layer of heat insulating material and positioned between the middle and inside wall is a layer of sound absorption material. Two symmetrical members are aligned parallel to each other within the absorption section with each member having an inner and an outer wall and a layer of sound absorption material therebetween. When the two symmetrical members are connected together, they form a hollow tubular inlet connector and a hollow tubular outlet connector which have parallel aligned axis. In addition, two longitudinally extending slots are constructed in each tubular connector. These slots communicate with each other by two separate passageways formed by the perforated inside wall of the absorption section and the outer walls of the two symmetrical members. These two passageways channel the exhaust gas through the silencer and out to the atmosphere.
