K4J, and 780 - K4M, and 800 or 801
A: under low loads, the oil vapours are rebreathed
in small quantities through the calibrated orifice
(6).

B: under medium and heavy loads, the oil vapours
are rebreathed in large quantities through the valve

A: Low load

B: Medium and high loads

- Rocker cover
- Oil vapour rebreathing duct
- Oil vapour rebreathing valve
- Air inlet duct
- Turbocharger
- Atmospheric pressure
A: At low load, the vacuum pressure prevailing in the
air inlet duct is below the spring calibration. Large
quantities of oil vapour are sucked back in by the vacuum
prevailing in the air inlet duct.
B: At medium or high load, the vacuum pressure prevailing
in the air inlet duct pulls the valve diaphragm,
small quantities of oil vapour are rebreathed in via a
calibrated jet.
