Abstract

Improvements in carburetors, and more particularly in carburetors with air valves for internal combustión engines, characterized in that the carburetor comprises a suction passage, a box next to said suction passage and divided into a first chamber and a second chamber by a movable wall, a sliding valve connected to said movable wall and slidably movable through an opening in the wall of the suction passage, said opening connecting said suction passage and said first chamber, said sliding valve with a part of the wall of the suction passage to provide a variable opening, pushing means acting on said sliding valve to push it towards said wall part, a mixing chamber formed in the suction passage between the sliding valve and a choke valve downstream of said sliding valve, being connected di second chamber to the mixing chamber while said first chamber is arranged to receive air at a pressure greater than that existing in the mixing chamber a flow of air to the mixing chamber, additional to the flow through said gap, can be adjusted by means of at least one valve in passage means through which a portion of said additional flow passes.
