FIELD: machine building.
SUBSTANCE: hydraulic mechanical device for chain tension consists of case (1) in form of hollow cylinder, of movable cover with circular groove (3) and ball back valve (6), also, cover forms plunger pair with case, of plunger (7) with stop elements creating step mechanism for arrest of backward stroke. Oil feeding channel (5) is made in cover (2) whereon there is additionally made a groove connected with oil supplying channel (5). Throttle orifice (14) is made on cover (2) and is overlapped with case (1).
EFFECT: increased reliability of design, reduced labour input of manufacture due to absence of additional circular grooves on cover.
