106, so that the cam 102 of valve actuating mechanism 1000, lift regulation eccentric wheel 113 and the middle three of swing arm roller 115 protect always
Hold fitting contact.
Further, as shown in figure 3, connecting portion 201 can be connected between the top surface of two fixed parts 202, and two
Fixed part 202 can be along the axially spaced of middle arm shaft 114.Fulcrum bearing 107 can be avoided by being thus connected portion 201, make branch
Bearing 107 can be located between two fixed parts 202, so that the unitary construction of valve actuating mechanism 1000 is compacter.
Further, the section of middle swing arm axis hole 203 is for circle and suitable for consolidating with the corresponding middle interference of arm shaft 114
It is fixed.
Further, each oil duct 205 further comprises multiple seed oil roads, and multiple seed oil roads are independent of one another and are spaced apart,
Multiple seed oil roads are located at the top of middle swing arm axis hole 203 and arranged successively along the circumference of middle swing arm axis hole 203.It is possible thereby to
Increase projected area of the lubricating oil to middle arm shaft 114, improve cooling and profit of the lubricating oil to middle arm shaft 114
Sliding effect.
Further, connecting portion 201 is integrally formed with spring limiting board 206.Thus the overall intensity of fixed support 108 is more
It is high.
Further, as shown in figure 3, spacing plane 208 can be along the axially extending of middle swing arm axis hole 203.Pass through axle
It is spacing to the spacing plane 208 and the progress of fulcrum bearing 107 face face of extension, improve the assembly precision of fixed support 108, convenient dress
Match somebody with somebody.
Further, the central axis of two middle swing arm axis holes 203 can overlap.Same cylinder can so be ensured
Two valves the installation site of middle swing arm 106 uniformity.
Preferred embodiment of the present utility model is these are only, it is all in this practicality not to limit the utility model
Within new spirit and principle, any modification, equivalent substitution and improvements made etc., guarantor of the present utility model should be included in
