Claims

[Scope of utility model registration request]

In a cylindrical engine equipped with a valve actuation stop mechanism driven by switching fluid pressure, a differential pressure responsive first switching control valve is provided to control switching of fluid pressure to the valve actuation stop mechanism. A differential pressure responsive second switching control valve capable of supplying control pressure into the working chamber of the first switching control valve is provided, and a hysteresis forming mechanism is provided in the second switching control valve in order to give the control pressure a hysteresis characteristic. A valve operation/stop mechanism control device for a cylinder engine, characterized in that:
