Abstract
PURPOSE: To reduce the area of venturi during low speed for improvement of atomization and to increase the amount of mixed air for (the) improvement of output by making variable the negative pressure in a piston valve for a variable venturi type carburetter.
CONSTITUTION: A negative pressure chamber 3 is formed inside a piston valve 1 for a variable venturi type carburetter. The piston valve 1 moves vertically in proportion to the negative pressure of a venturi tube 9 transmitted from a negative pressure intake bore 1a. A needle valve 11 is vertically installed to a mixing chamber 10 facing the valve 1. The needle valve 11 is so arranged that its end may be inserted into the negative pressure intake bore 1a. With this construction, the transmission of negative pressure from the intake bore 1a is reduced during low speed, thereby moving the piston valve 1 downward while during high speed the negative pressure is transmitted as usual.
