燃機関のバルブスプリング装置に関する。[Detailed description of the invention] The present invention relates to a valve spring device that gives a closing habit to the supply and exhaust valves of an internal combustion engine. The present invention relates to a valve spring device for an internal combustion engine in which the spring does not interfere with obstacles (such as a cylinder head wall) on the other side.

スプリングは採用できない。 In recent years, there has been a trend to increase the valve spring force of the exhaust valve in order to improve the exhaust braking force, and the valve spring is often made into a barrel-shaped spring shown by reference numeral 1 in FIG. In this case, as shown in FIG. 2, if the wall 2A at the top of the cylinder head 2 is in a position where it is likely to interfere, the barrel spring 1' will get caught on the wall 2A, making it difficult to assemble it, or even if it cannot be assembled. Even if the gap S1 with the wall portion 2A is small, the operation will become unstable, and a spring with a large diameter cannot be used.
本考案の目的は上記の問題点を解消した内燃機
関のたる形バルブスプリング装置を提供すること

定量だけ偏心装着させた点に特徴がある。 The purpose of the present invention is to provide a barrel-shaped valve spring device for an internal combustion engine that solves the above-mentioned problems. It is distinctive in that it is installed.

ム５と同心に配置してある。 An embodiment of the present invention will be described below with reference to the drawings. FIG. 3 shows a longitudinal cross-sectional view of an embodiment of the present invention, in which the upper and lower valve spring seats 3 and 4 supporting the barrel spring 1 are both positioned against the valve stem 5 to prevent the valve head 2 from being an obstacle. It is eccentric by an amount S2 in the direction away from the wall portion 2A. However, in this embodiment, the spring 6 provided on the inside is arranged concentrically with the valve stem 5 as before.
第４図にはたる形スプリング１の偏心装着状態
を水平断面図で示してある。 FIG. 4 shows a horizontal sectional view of the barrel-shaped spring 1 in an eccentrically mounted state.

をもつたる形スプリングを組込むことができる。 The device of the present invention having the above structure allows the barrel-shaped spring 1 to be installed at a sufficient distance from the wall portion 2A of the cylinder head 2, which is an obstacle, without changing the position of the valve stem 5, which is more convenient than before. Since it is also possible to incorporate a barrel-shaped spring 1 with a large diameter, it is possible to incorporate a barrel-shaped spring having the force necessary to obtain the exhaust brake pressure.
