The utility model discloses an automatic tensioning ware of motor head annex fluid pressure type, this automation tensioning ware includes the cylinder body, installs just will in the cylinder body two hydraulic pressure held the piston in chamber about the cylinder body was separated to become, be equipped with check valve and damping hole on the piston, the hydraulic oil warp the check valve with the damping hole is in the reciprocal flow produced asymmetric damping during two hydraulic pressure held the chamber, formation is in piston rod extension on the piston is passed sealing unit, automatic tensioning ware is still including installing the air receiver that holds the chamber side at another hydraulic pressure, the air receiver can compensate because piston motion causes it is poorthat from top to bottom hydraulic pressure holds the chamber volume, make hydraulic oil can be freely through the check valve and reciprocate in the damping hole the hydraulic pressure chamber produces the asymmetric damping
