ことを特徴とする休止機能付き動弁装置。A cam that rotates according to the rotation of the internal combustion engine's crankshaft,
a rocker arm that engages at one end with a valve body of an on-off valve provided in a combustion chamber of the engine and responds to the cam; a piston plunger that swingably supports the other end of the rocker arm; A valve train with a stop function, including a casing that slidably accommodates a piston plunger and forms a pressure receiving chamber between the piston plunger and a control mechanism that controls discharge of pressurized fluid within the pressure receiving chamber. The control mechanism includes a valve guide that is inserted into the casing from an open end thereof and forms a communication path that communicates the pressure receiving chamber with the atmosphere, and a valve guide that is slidably inserted into the valve guide and that forms a communication path that communicates the pressure receiving chamber with the atmosphere. a poppet valve body provided in the middle of the passage to prevent backflow of fluid from the pressure receiving chamber;
A resilient member that always biases the poppet valve body in the valve closing direction, and a drive means that opens the poppet valve body against the biasing force of the resilient member in accordance with the load condition i of the engine. A valve train with a stop function, which is characterized by:
