Automatic natyazhitel of a gas-distributing chain - the general information

Components of an automatic natyazhitel of a gas-distributing chain

1 — the Case of a natyazhitel
2 — the Spring
3 — the Plunger

4 — the Spring
5 — the Adjusting rod
6 — the plunger Case


The design of an automatic natyazhitel of a gas-distributing chain is shown on an illustration.

The left and right driving chains are equipped by individual natyazhitel. Natyazhiteli of hydraulic type use pressure of motive oil and are capable to support automatically a tension of driving chains in the set range, excepting thereby need for manual adjustment.

In the case of a natyazhitel there is an oil opening which on the established natyazhitel is joined to the corresponding opening in the block of cylinders. In the case of a natyazhitel the chamber of a high pressure with a control ball is located. Pressure in a chamber is regulated by the reducing valve. Thanks to a plunger with an external carving the natyazhitel is capable to hold a tightness of a driving chain at the set level even at the killed engine.
