The displacement possible cam base material is prepared for the displacement position which two or more alienates between the rotary bearing of the cam shaft itself and the cam shaft itself the valve gear and the internal combustion engine for the gaseous exchange valve of the internal combustion engine

摘要

At the same time and this invention the gaseous exchange valve of the internal combustion engine one for (2) regarding the valve gear (1) is something, the internal combustion engine at least one cam shaft itself (4) and the cam shaft itself (4) on is displacement possible in axial direction the cam group which three where the cam border differs cams (13,14,15) it possesses at least (6,7) at least one which one it possesses at least cam base material (5) and the cam group (6,7) the cam (13,14,15) in the displacement position which a quantity which responds to number alienates the cam base material (5) the cam shaft itself (4) the device which is made to displace to axial direction at on (21,22,23,24,25) withSpring energization in order person in charge stopping to do the ball which is done (28) the person in charge stopping device which it possesses (26) with, it has the cam base material (5) for the displacement position which is alienated. At the time of this inventing in order to decrease the especially necessary installation space, the cam shaft itself (4) the rotary bearing where the cam base material (5) position is locked with both sides axial support is done in (3), the person in charge stopping device (26) the ball which spring energization is done (28), the cam shaft itself (4) the storage hollow part (27) is laid out, holding down the axial direction where position is locked two displacement positions outside in respectively, (3,18) the pushing overpowers the cam base material (5).
