The oil enters the through hole 621 of the second pusher 62 from the drive oil passage 65: 'Bump by =6 4 U 6 4 1 1 and the guide of the first piston 6 4 3 enter the groove 6431 of the first piston 643, and at the same time, the position machine: = road 6_, thereby making the plug of the second piston first-pushing member 61 side Positioned by 1 Appropriate position, and the first piston 643 can be positioned in the second push material ¥ plug 6 4 3 _ 2 to form the respective pendulum =: at this time, the first pusher 6 1 and the second push 2 5 and the intake air 3 3 / contact, - pusher 6 2 its front end of the offset portion 6, and the second pusher 6 2 behind the push-up roller 201144574 3 6 2 Another engine (four) line button change zm3 2 material low system 3 control center E c ', cut to six lift opening, engine hydraulic cylinder _, _ ^ 4_ oil from crane _ 6 into the movement _ hole 6 = when: ^ machine, from calving, benefit Yu Di-actuator 6 2 through hole 6 2 3 in the plug 6 ^ to the side of the oil pressure to move the first piston 6 4 3 and the second live in the direction of the first pusher member 62 - the piston 643 is made by the plug of the second pusher 6 2, and the second piston 6 44 is positioned at an appropriate position, and the second wire 6 - = Between :::62, -1=2, the moving form, due to the pusher roller 6!4 behind the first pusher 61 and the camshaft 3 3 6 - intake cam 3 3 6 1 (ie high lift cam ) contact, and the first pushing member 6 2 has a front end falling portion 6 2 5 and an intake valve 3 3 2 phase contact: therefore, the second pushing member 62 is driven by the first pushing member 61, that is, the predetermined degree of the first feeding cam 3 3 6 1 (ie, the high lift cam) will be advanced into the «3 3 2 Highly smashed, so that the engine 3 can be achieved. The utility model has the advantages that the first intake cam 3 3 6 1 , the second intake cam 3 3 6 2 and the exhaust cam 3 3 6 3, and the intake air cylinder are respectively disposed on the cam shaft 33 6 . The pushing member 6 has a second shaft 2 of the first shaft member 6, and is connected to the through hole 613 of the first pushing member 61 and the through hole 6 201144574 2 3 of the second pushing member 6 to form a hydraulic pressure. Cylinder 6 4, a bomber 6 4 2 is set in the oil red 6 4 , and the first piston 6 \ 3 ^ 2 can be pushed by the secret spring 6 4 2

Further, by the first pusher 6 1 and the second pusher 6 2, the records 6 i 2, 6 2 2 are placed between the positioning holes 6 ii, 6 2 i and the pressing portion 6 2 5 , The through holes 6丄3, 6 2 3 of the first pusher 6i and the second pusher 6 2 are located between the ejector rollers 6 13 and 6232 and the positioning holes 611 and 621, and are located at the push wheel 614. 624 is positioned above the center line A of the positioning hole Chuan and 621, thereby effectively reducing the height of the overall cylinder head 33. In summary, the present invention, by the above-mentioned structure, can improve the lack of conventional use, and can achieve the (4) and efficacy of the collection, and the red meets the practicality, novelty, and progressive requirements described in the Wei patent.
