Description
【考案の詳細な説明】 本考案は内燃機関の動弁装置に関する。[Detailed explanation of the idea] The present invention relates to a valve train for an internal combustion engine.
一般に燃焼室に放射状に配設されるバルブステ

ームを介在させ、これによりバルブステムを軸芯
方向に押圧している。 In general, in a valve train in which a camshaft drives multiple valve stems arranged radially in the combustion chamber, the pressing direction of the Rocker arm and the axial direction of the valve stem are difficult to match. A sub-rocker arm is interposed between the valve stem and the valve stem, thereby pressing the valve stem in the axial direction.

する。 The present invention aims to facilitate the positioning of the shafts of the rocker arm and the sub rocker arm, and to simplify the means for fixing the shafts. In a valve operating system for an internal combustion engine, in which intake and exhaust valve stems are disposed radially in a radial direction, and the valve stems are interlocked with a camshaft via a rocker arm and a sub-rocker arm, the swing shaft of the rocker arm and the sub-rocker arm and a rocking shaft are disposed in the cylinder head so that their axes intersect with each other, and the end surface of the one shaft is positioned by abutting against the side surface of the other shaft.

整ねじ、１３はヘツドカバを示す。 To explain this with reference to the illustrated embodiment, 1 is a cylinder, 2 is a cylinder head, and the cylinder head 2 has two intake valves 3 and an exhaust valve 4 in its combustion chamber.
The two valve stems 3a and 4a are attached radially, and the valve stem 3
Four sub-rocker arms 5 and four rocker arms 6 are provided facing the tips of the sub-rocker arms 5 and 4a, respectively, and two of the rocker arms 6 are each supported by a parallel pair of rocker arm shafts 7, 7. At the same time, the sub-rocker arm 5 has separate sub-rocker arm shafts 8, 8 disposed parallel to a plane orthogonal to the rocker arm shafts 7, 7.
The sub-locker arm shaft 8,
One end of the rocker arm 8 is fitted into a shaft hole formed integrally with the head 2, and the other end is supported by a spring 9 so as to come into contact with the side surface of the rocker arm shafts 7, 7. In the figure, 10 is a camshaft, 11 is a valve spring, 12 is a rocker arm adjustment screw, and 13 is a head cover.

とができる効果を有する。 In this way, according to the present invention, the rocking shaft 7 of the rocker arm 6 and the rocking shaft 8 of the sub-rocker arm 5 are arranged in the cylinder head 2 so that their axes intersect with each other, and one of the shafts is Since the end face of the swing shaft 8 is positioned by abutting against the side surface of the other shaft 7, the positioning of the swing shaft 8 is easy and the fixing means is simple even though the sub rocker arm 5 is provided. It has the effect of making its installation significantly easier.
