Title: CARBURETTOR FOR AN INTERNAL COMBUSTION ENGINE OF AN IMPLEMENT
Abstract:
The subject matter of the invention is a carburettor (100) for an internal combustion engine of an implement having an air funnel (10), in which a throttle valve (12) is arranged, and having a control chamber (16) which is connected to a fuel tank, wherein the control chamber (16) is connected to the air funnel (10) via a fuel line (15) which opens into an interior chamber (11) of the air funnel (10), wherein a pumping chamber (18) with a diaphragm element (19) is arranged in the fuel line (15) between the control chamber (16) and the opening (17) of the fuel line (15) into the interior chamber (11) of the air funnel (10), wherein the pumping chamber (18) has a bottom body (22) which interacts with the diaphragm element (19), wherein the fuel which is introduced via the fuel line (15) into the pumping chamber (18) flows in an intermediate space (25) which is configured between the diaphragm element (19) and the bottom body (22), wherein the bottom body (22) has a flow duct (26) and a plateau region (27), wherein the spacing (AP) of the plateau region (27) from the diaphragm element (19) is smaller than the spacing (AS) of a bottom region (28) of the flow duct (26) from the diaphragm element (19).
