Abstract

1434002 Spray carburetters NISSAN MOTOR CO Ltd 28 March 1974 [3 April 1973] 13813/74 Heading F1B The float chamber 19 is connected to the induction passage 13 between the choke and throttle valves 11 and 21 under the control of a valve 28 in the connecting passage 25 when the engine ignition is switched off and the solenoid 29 is de-energized. The passage 25 may be indirectly connected to the passage 13 by a pipe 25B communicating with the suction chamber 15 of the choke piston 11. The connection to atmosphere at port 27C may be replaced by a connection to the chamber 19 controlled by a second valve operating simultaneously with the valve 28.
