2. Cover of a head of the block of cylinders
3. Oil separator chamber

4. The highway of soaked-up air
5. The highway of deleted air
Ventilation top partial / full loading
6. Butterfly valve
7. Throttle in diameter of 1,1 mm

10. Support of the pump of the amplifier of a steering
11. Oil separator chamber
12. Space for a crank
13. The Retsirkulyatsionny pipe for oil (siphon)
14. Oil pallet
15. Management case
16. Case of a crank of the cylinder
17. Head of the block of cylinders

And. Fresh air
Century. Blown gases
D. Connecting element

The mix of ventilated gases is sucked in in the combustion chamber from the chamber of a crank (12) via the chamber of a separator of oil (11) and the highway of removal of air, and also a throttle (7) in power setting from "idling to average partial loading". In an oil separator oil separates from a gas mix and arrives through a by-pass opening and a by-pass pipe (13) in the oil pallet.

In order to avoid penetration of slags into engine oil the part of soaked-up fresh air separates in a connecting element (D) and goes to the krivoshipny chamber through the highway of deleted air (5), the chamber of a separator of oil (3), a case of a chain (18) and the case of management (15).
