Abstract
An acceleration pump of a carburetor is constituted by a cylinder and a piston slidably received by the cylinder, so that the delivery rate of the acceleration fuel may be changed in accordance with the change of stroke of the piston within the cylinder. The stroke of the piston is limited by a stopper member adapted to be directly actuated by an incompressible temperature detecting element. The stopper member is so arranged as to be moved in the direction perpendicular to the stroking direction of the piston, so as to provide a fine adjustment of the stroke of the piston and, accordingly, an accurate control of the delivery of acceleration fuel in relation with the change of the engine temperature.
