](R
When the throttle valves
(13)
are opened, the lever
(28)
attached to
linkage
(2'7),
pushes a rod
(29)
and spring
(a),
this in turn actuating a lever
(32)
thus operating
the diaphragm
(31).
The diaphragm
is
held in position
by
o spring
(30).
The diaphragm,pumps fuel in two separate circuits through the delivery valves
(24)
and the pump jets
(26),
then to the main barrels
(10)
when the throttle valves are
closed, the diophrogrn returns to its off position, pushed by the spring
(3),
sucking
fuel from the float chamber via volve
(25)
during this operation.
