Flap V 1 is controlled by C 1. It is controlled pneumatically by vacuurr
The vacuum intake is at the carburettor
The flap is controlled by a pneumatic piston subjected to vacrrum via a switch When control C 1 is positioned
between the small blue square and the red square the piston,in the switch is lifted ( fiq ( A ) ) vacuum intake
is cut off’ the supply pipe to the pneumatic piston is at atmospheric pressure flap V 1 blanks off intake E 2, and
air drawn into the intake on the bonnet comes from outside With the engine runninc and control C 1 positioned
between both blue squares ( fiq. ( B ) ) the piston in the switch comes down under the action of its spring.
supply
pipe to the pneumatic piston is no lonqer under atmospheric pressure but under the action of the vacuum, and
flap V 1 via the pneumatic piston blanks off intake E 1’ the air drawn in comes from the passenqer compartment,
( recycling position ).
NOTE Identification mark for fittinq the one way valve the outer diameter is reduced on the side of the 3-way union V. FAST IDLING SPEED CONTROL
This control allows for a faster idling speed when the compressor is operatinq
A vacuum capsule incorporated in the carburettor slightly opens the first choke butterfly by means of a small rod.
The amount of opening is adjustable by means of a screw on top of the vacuum capsule.
An electromvalve fitted to the R.H side of the front subframe and supplied at the same time as the electro-maqnetic
clutch for the compressor controls the supply of vacuum to the capsule. t FRONT

B. VEHICLES FITTED WITH A SANI(Y0 COMPRESSOR
NOTE Filling operations on CI vehicle fitted with a and differ from the (< ASPERA-FRIGO 1) compressor only in as much as there are no screws for opening and closing
the valves.
The act of connecting a flexible pipe onto the intake valve (2) of the compressor automatically opens the valve. Checking the oil level on the cc SANKYO ~ncompressor
