Abstract: A nozzle for atomizing a liquid which includes a nozzle housing, a nozzle body supported in an annular groove of the nozzle housing which body defines a nozzle orifice and a valve body which coacts with the nozzle orifice to close and open the orifice by movement of the valve body along a line through the center of the orifice. The nozzle body is movable in the groove in a lateral direction relative to the direction of the opening and closing movement of the valve body.

Abstract: An injection carburetor device for adjusting the fuel-air ratio which includes an injection nozzle, a valve body seatable in the nozzle, a first sensing member which senses the velocity of the air passing through the carburetor and connected to the valve body through a linkage which is comprised of a rocker arm and cam surfaces capable of being abutted by the free end of the rocker arm and a second sensing member which senses the pressure in the induction pipe of the engine to which the carburetor is attached. The second sensing member moves the free end of the rocker arm laterally to have its other end contact one of the cam surfaces.
