FIELD: mechanical engineering. ^ SUBSTANCE: invention designed for transmitting rotation by endless flexible members, for instance, in camshaft drive mechanism of internal combustion engine. Proposed tensioner has housing 1 with hydraulic chamber, plunger 3 with gear rack 5, spring 6, ratchet member and ratchet member stop made in form of link 14. Ratchet member is essentially double-arm anchor lever 9 with hinge support on housing. Link 14 can move in under action of spring 11 pressing ratchet member which engages with gear rack 5 precluding back movement of plunger 3. ^ EFFECT: improved reliability of adjustment and operation of tensioner. ^ 3 cl, 1 dwg |
