Anordning innefattande ett luftfilter och en membranförgasare

摘要

The invention is directed to an arrangement of an air filter (1) and a membrane carburetor (2). The membrane carburetor (2) has an intake channel section (3) configured in the carburetor housing (4) and fuel-conducting channels (6) open into the intake channel section (3). The channels (6) are supplied from a fuel-filled control chamber (7) which is configured in the carburetor housing (4). The control chamber (7) is partitioned from a compensation chamber (11) via a control membrane (10). The compensation chamber (11) communicates with the housing (14, 16) of the air filter (1) via a compensation channel (13) downstream of an air filter element (39). The air filter housing (14) engages over the membrane carburetor (2) essentially on the side of the compensation chamber (11) and the clean chamber (24) of the air filter housing (14) communicates with the intake channel section via a connecting stub (37) which lies approximately at right angles to the intake channel section (3). The connecting stub (37) is used as a connection between the clean chamber (24) of the air filter (1) and a flow space (26) mounted forward of the intake channel section (3) in order to ensure a reliable compensation where available space is tight. The volume of the flow space (26) is greater than the volume of the connecting stub (37) and the compensation channel (13) branches away from the flow space (26).
