Claims

[Scope of utility model registration request]

a valve train cam having two types of cam profiles adapted to the operating conditions of the engine adjacent to each other in the axial direction; a swing arm shaft having an axis substantially parallel to the axis of the valve train cam; A swing arm is pivotally supported on a swing arm shaft and is swung when a roller provided at the other end comes into contact with the valve operating cam; a push rod for opening and closing an exhaust valve; and an actuator connected to the swing arm shaft and displacing the same shaft in the axial direction to selectively bring the swing arm into contact with one of the two types of cam profiles; The swing arm is supported so as to follow the swing arm shaft via an elastic device in response to displacement of the swing arm shaft in the direction of moving up the radial step of the two types of cam profiles. A valve train for an engine.
