Chain tensioner timing

Fig. 2.26. Chain tensioner timing: 1 - hole ratchet; 2 - opening the oil supply; 3 - return valve; 4 - spring piston; 5 - the piston; 6 - rack; 7 - ratchet; 8 - a spring ratchet; 9 - the cross section

Chain tensioner timing - oil. The tension of the chain valve timing is kept constant by using oil pressure and the spring force of the chain tensioner. Oil chain tensioner has the following parts: a piston spring, which acts on the tensioner arm; check valve, which keeps the force on the tensioning lever (Fig. 2.26).
