PROBLEM TO BE SOLVED: To provide a pump used in a direct injection internal combustion engine. SOLUTION: A fuel amount regulation injection device for an internal combustion engine having a pump is indicated. The device comprises an air feed chamber to periodically change an air pressure in a room; a fuel feed chamber 12, and an operation chamber 14 related to the fuel feed chamber 12 and communicated with the air feed chamber so that an internal pressure is changed by a frequency corresponding to the fluctuation of an air pressure in an air feed chamber. The fuel feed chamber 12 is separated away from an operation chamber 14 by a pump member 4 to feed fuel to the fuel feed chamber 12 according to the change of a pressure in the operation chamber 14 and feed the fuel therefrom. |
