Claims

[Scope of utility model registration request]

In an internal combustion engine in which at least a pair of mutually adjacent intake valves or exhaust valves having the same function are arranged for one cylinder, an arm is provided when the upper ends of the pair of intake valves or exhaust valves come into contact with each other. A 10th lever arm and a 20th lever arm are swingably supported on a common support shaft having an axis perpendicular to the operating direction of the valve and fixed to the engine body. A cylinder hole is drilled that opens toward the claw arm side and accommodates the plunger, and a guide hole that opens toward the tenth claw arm and into which the plunger can be inserted is bored in the 20th claw arm. A hydraulic working chamber defined between the bottom and the rear end of the plunger is connected to a hydraulic power source via a hydraulic switching valve that switches between supplying and stopping hydraulic pressure to the working chamber, and the tenth lever arm includes: - A valve train with a stop function for an internal combustion engine, characterized by being provided with a cam slipper that slides into contact with a cam that rotates according to the operation of the engine.
