Abstract
The invention relates to the combination of an air filter and a membrane carburetor (1). The membrane carburetor (1) has an intake channel section (3) configured in the carburetor housing (2) into which the fuel-conducting channels (4, 4′) open which are fed from a control chamber (5) of the carburetor housing (2). The control chamber (5) is separated by a control membrane (6) from the compensation chamber (7). A compensation channel (11) leads from the compensation chamber (7) into a flow space (9). A connecting piece (8) is led into the flow space (9) as a connection of the intake channel section (3) of the membrane carburetor (1) with the flow space (9). The compensation channel (11) and the connecting piece (8) open into the housing (21) on the clean air side (23). The housing (21) forms the flow space (9). The compensation channel (11) is guided into the housing (21) via a segment (10) in the connecting piece (8) to provide a simpler assembly and constructive configuration of the compensation connection. The opening (15) of the compensation channel (11) defines a first plane (17). The opening (16) of the connecting piece (8) defines a second plane (18). The planes (17, 1…
