SPECIAL FEATURES
From 1977 models the fast-idle electro-valve ( 9) is manufactured by 1, PIERBURG 1).
When it is not enerqized the electro-valve lets low pressure through towards the carburettor capsule (fast
idle ) contrary to the (1 WEBER )) electromvalve fitted previously.
Fitting the N PIERBURG )) electro-valve necessitates fitting a relay (8) which is enerqized when the air-
conditioning system is operating This relay, with its c( o/)t/i 1) contact cuts off supply to electro-valve (9)
which therefore produces fast idle. DESCRIPTION OF COMPONENTS :
1
- Heater relay ( .s/o~/~/Q~c/ )
2 - Air blower ( .S~n~~dnr(i i
3 - Speed control for blower ( S/nr/clnrt/ J
4 - Regulating thermostat
5 - Air-conditioning switch 6
- Pressure switch ( 01, dc,-rt,cr/t,rit,,q lnr~k ) 7
- Compressor clutch
