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).

  6. 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.
