Claims

[Scope of utility model registration request]

(1) a cam that rotates in accordance with the rotation of the crankshaft of an internal combustion engine; 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 lining that swingably supports the other end of the rocker arm and forms a pressure receiving chamber between the piston plunger and the piston plunger that slidably accommodates the piston plunger; and the pressure receiving chamber. a control mechanism for controlling supply of fluid pressure to a valve train, the control mechanism supplying fluid pressure to a fluid pressure passage communicating with the pressure receiving chamber and to the fluid pressure passage; a check valve that is provided in the fluid pressure passage and prevents backflow of fluid from the pressure receiving chamber; and a check valve that controls the push-opening of the check valve depending on the load condition of the engine. What is claimed is: 1. A valve train with a stop function, characterized by comprising a valve control means.

(2) The check valve control means includes a resilient member that normally biases the valve body of the check valve in the valve closing direction, and a resilient member that biases the valve body of the check valve in the valve-closing direction in accordance with the load condition of the engine. The valve operating device with a stop function according to claim 1, which is characterized by comprising a driving means for opening the valve against the biasing force of the generating member.
