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).

摘要： 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, 18) are separated from each other and these planes preferably intersect.

摘要： A diaphragm carburetor for an internal combustion engine that operates with scavenging is provided, especially for the two-cycle engine in a manually guided implement. The carburetor has a housing in which is formed an intake channel portion in which is disposed a butterfly valve that is rotatably held via a butterfly valve shaft. The carburetor has at least one air channel that supplies additional combustion air and that is provided with an air valve that is rotatably held via an air valve shaft. The air valve is, at least in one angular range, coupled to the movement of the butterfly valve, whereby the coupling includes a butterfly valve lever that is fixedly connected with the butterfly valve shaft, and an air valve lever that is fixedly connected with the air valve shaft. Disposed on one of the levers is a driver member that at least in one angular range slides upon the other lever between an outer contact point and an inner contact point.

摘要： A portable hand-guided work apparatus (1), such as a motor-driven chain saw, cutoff machine or the like, includes an internal combustion engine (2) and an air filter (10). At least one air channel (8) and an intake channel (7) are provided which fluidly connect the internal combustion engine (2) to the clean side of the air filter (10). The intake channel (7) is configured at least partially in a carburetor (9). The air channel (8) opens at an air channel opening (13, 13′, 13″) and the intake channel (7) opens at an intake opening (12) at the clean side of the air filter (10). Air channel opening (13, 13′, 13″) and intake opening (12) open spatially separate from each other at the clean side of the air filter (10). To prevent the entry of fuel into the air channel (8) from the intake channel (7), the intake opening (12) in the normal work position of the work apparatus (1), seen in the effective direction (17) of the gravity force, has an elevation offset (a, a′, a″) relative to the air channel opening (13, 13′, 13″).
