A control diaphragm for controlling a fuel feed in a diaphragm carburetor of an internal combustion engine, includes a central, substantially flat feeling region, a functional region circumferentially extending around the feeling region in a concentric manner, and a peripheral fastening border for fastening the control diaphragm. The control diaphragm closes off a control chamber of the diaphragm carburetor in a sealing manner in the installed state and is operatively connected by the central feeling region to a controlling lever of the diaphragm carburetor arranged in the control chamber, which controlling lever feels the axial deflection of the feeling region in accordance with an operating-related pressure change in the control chamber. The control diaphragm is composed of a temperature- and fuel-resistant, non-elastomeric and uniformly thick plastic film, in which a plurality of concentric corrugations forming the functional region are formed so that axial deflection of the feeling region progresses in dependence on the operating-related pressure change in the control chamber in accordance with a predefined displacement/pressure characteristic curve.

The invention relates to a control device for a diaphragm carburettor, said control device comprising a control diaphragm and a control lever, wherein the control diaphragm has a central scanning region, a functional region concentrically surrounding and adjacent to the scanning region, and a peripheral securing edge for securing the control diaphragm in the diaphragm carburettor, and wherein the control lever is mounted with a hinge in the diaphragm carburettor in the assembled position, with a first end operatively connected to a control valve of the diaphragm carburettor and with a second end contacting the central scanning region of the control membrane, such that same can scan an axial deflection of the scanning region depending on a operation-dependent pressure change. According to the invention, on the second end, the control lever has a circular scanning plate that is flat on the diaphragm side, wherein the diameter of the scanning plate is greater than 50 per cent, preferably greater than 85 per cent, particularly preferably greater than 90 per cent of the diameter of the scanning region of the control diaphragm.
In the case of a control diaphragm for controlling a supply of fuel in a diaphragm carburetor of an internal combustion engine, comprising a central sensing region (1), a functional region (2) which encloses the sensing region (1) concentrically, and a peripheral fastening border (3) for fastening the control diaphragm in the diaphragm carburetor; wherein, in the installed state, the control diaphragm closes a control chamber (5) of the diaphragm carburetor sealingly and is operatively connected via the central sensing region (1) to a control lever (4) of the diaphragm carburetor, which control lever (4) is arranged in the control chamber (5) and senses the axial deflection of the sensing region (1) in a manner which is dependent on an operation-induced pressure change in the control chamber (5); it is provided that the control diaphragm consists in one piece of temperature-resistant and fuel-resistant, non-elastomeric plastic; in that the functional region (2) between the fastening border (3) and the sensing region (1) is configured by way of a multiplicity of concentric beads (8), wherein the outermost concentric bead directly adjoins the fastening border (3), and the radius of the outermost concentric bead corresponds substantially to the radius of the control chamber; that the sensing region (1) directly adjoins the innermost concentric bead of the functional region (2); and the radius of the sensing region (1) corresponds to from 5 to 25% of the outer radius of the functional region (2); and in that the sensing region (1) has a reinforcing means (10, 11).
