Specific implementation mode

Illustrate that the embodiment of the utility model, those skilled in the art can be by these by particular specific embodiment below Content disclosed by specification understands other advantages and effect of the utility model easily.

It please refers to Fig.1 to Fig. 7.It should be clear that structure, ratio, size etc. depicted in this specification institute accompanying drawings, only to Coordinate the revealed content of specification, so that those skilled in the art understands and reads, is not limited to the utility model Enforceable qualifications, therefore do not have technical essential meaning, the modification of any structure, the change of proportionate relationship or size Adjustment, in the case where not influencing the effect of the utility model can be generated and the purpose that can reach, should all still fall in the utility model Revealed technology contents obtain in the range of capable of covering.Meanwhile in this specification it is cited as "upper", "lower", " left side ", The term on " right side ", " centre " and " one " etc. is merely convenient to being illustrated for narration, rather than enforceable to limit the utility model Range, relativeness are altered or modified, enforceable when being also considered as the utility model in the case where changing technology contents without essence Scope.

Referring to Fig. 1, the V-shaped arrangement of valve on the cylinder head of engine.

Fig. 2 to Fig. 7 is please referred to, the utility model provides a kind of modified gear, including objective table A1, actuator B and limit Mechanism C.
