CARBURETOR SYSTEM HAVING A FLUIDIC PROPORTIONAL AMPLIFIER |
摘要 |
A carburetor having a fluidic proportioning device adapted to deliver fuel to an air-intake conduit in proportion to air pressure differential established across the control ports of the fluidic device by regions of different pressures established within the venturi shape of the air-intake conduit and the variable position of a throttle valve, the fluidic proportioning device including a first control port responsive to air pressure in an enlarged portion of the air-intake conduit, a second control port opposing the first control port and responsive to low air pressure in that portion of the air-intake conduit restricted by the throttle plate at low engine speeds and a third control port additively connected to the second control port and responsive to pressure within a narrow portion of the air-intake conduit.
