An atmospheric pressure compensation device has a reed valve of a resiliently bendable sheet material extending over a flat valve seat which defines therein an opening leading to an air passage to be connected to an air bleed of a carburetor, for example. The angular position of the freely bendable end portion of the reed valve relative to the valve seat is varied by a bellows member which is expansible and contractible in response to variation in the atmospheric pressure, to thereby control the rate of air flow through the opening and the passage to the air bleed. A fulcrum member is disposed in engagement with the reed valve to urge the same against the valve seat. The point of engagement of the fulcrum member with the reed valve is variable along the length thereof to vary the freely bendable length of the reed valve.
