Abstract

1353130 Spray carburetters FORD MOTOR CO Ltd 11 Oct 1972 [21 Oct 1971] 46827/71 Heading F1B [Also in Division F2] A valve comprises a valve body including a second passage 48, Fig. 1 having two openings and located at least in part within a first passage 46, one of the openings being located a fixed distance from the first passage inlet opening, the second passage including a tapered portion 54 forming a first valve seat, a second valve seat 56 proximate the first passage inlet opening and a valve-member 52 in the second passage movable between the seats. A carburetter float chamber is vented to an air filter via seat 56 and passage 46 when the ball valve is held off seat 56 by intake vacuum applied via conduit 58 and passage 48. When the engine stops the ball returns to seat 56. Passage 50 vents fuel vapour to a carbon fuel vapour storage cannister together with fuel vapour from a vehicle fuel tank via passage 66. During engine operation fuel vapour is purged from cannister 60 via line 68 to the air inlet.
