Beschreibung
Zusammenfassung:	The invention discloses a hydraulic tappet and valve rocker arm combined device. The device can reduce transverse friction force borne by a valve bridge and reduce abrasion. The hydraulic tappet and valve rocker arm combined device comprises a rocker arm shaft, a valve rocker arm, a hydraulic tappet, a roller and a valve bridge, and the valve rocker arm is arranged on the rocker arm shaft in a sleeving manner and used for swinging with the axis of the rocker arm shaft as the axis and the length of the valve rocker arm as the radius. The hydraulic tappet is arranged at one end of the valve rocker arm and can move together with the valve rocker arm; the roller is arranged at the lower end of the hydraulic tappet and can move together with the hydraulic tappet; and a contact plane is arranged at the top of the valve bridge, the contact plane is in contact with the hydraulic tappet through the roller, and when the hydraulic tappet abuts against the contact plane to enable the valve bridge to move along with the h
