A membrane carburetor ( 1 ) has a control chamber ( 13 ) which is connected via at least one fuel opening ( 9, 10 ) to an intake channel ( 3 ). The control chamber ( 13 ) is delimited by a control membrane ( 14 ). A fuel line ( 54 ) opens into the control chamber ( 13 ) via an inlet valve ( 15 ). The inlet valve ( 15 ) opens in dependence upon the deflection of the control membrane ( 14 ). The membrane carburetor ( 1 ) has an acceleration pump ( 30 ) which is actuated in dependence upon the position of a throttle element held in the intake channel ( 3 ). A good acceleration enrichment and a stable running of the internal combustion engine are achieved when the acceleration pump ( 30 ) operates hydraulically on at least one actuating member in the control chamber ( 13 ).
