Embodiment Construction
[0116] According to an embodiment of the present invention, as figure 1 , 2 As shown in FIG. and 3 , the engine valve drive 100 may include a housing 210 , a start piston 162 , a drive piston 130 , a linkage mechanism 182 , and one or more of a guide mechanism 137 , an anti-rotation mechanism 138 , and a positioning mechanism 150 .
[0117] The case 210 may be the rocker arm or valve bridge of the engine. In this embodiment, the box body 210 is a rocker arm, which can be similar to the rocker arm (210b) of EP2384396. like figure 1 As shown, the rocker arm is mounted on a rocker arm shaft (not shown) through hole 212 .
[0118] like figure 1 As shown, the housing 210 includes an actuation piston bore 260 and a drive piston bore 190 . Preferably, the actuation piston bore 260 and the drive piston bore 190 intersect each other perpendicularly. The activation piston 162 is slidably disposed in the activation piston bore 260 . The drive piston 130 is disposed in the drive pi...
