2.1.2.4. Natyazhitel of a chain

Fig. 2.16. Natyazhitel of a chain: 1 – cam spring; 2 – cam; 3 – plunger; 4 – spring


Natyazhitel of a chain uses a spring and pressure of oil for constant maintenance of an appropriate tension of a chain. Natyazhitel of a chain reduces the noise made by a chain. Also the ratchet mechanism is used. For improvement of operational reliability the natyazhitel of a chain has the design providing a possibility of his removal and installation outside of a gas distribution mechanism drive chain cover.
