    Abstract: PROBLEM TO BE SOLVED: To provide a valve variable operation system for an internal combustion engine capable of perfectly and quickly achieving filling of a high-pressure side of a system in any operating condition.SOLUTION: This system includes a second check valve hydraulically connected between a first tank and a pressurized fluid chamber. The second check valve allows the only flow of a fluid directing from the first tank to the pressurized fluid chamber, and the second check valve and a solenoid valve are hydraulically connected in parallel with each other and allows supply of the fluid from the first tank to the pressurized fluid chamber. With this structure, in a filling process over the whole of the pressurized fluid chamber and on a high pressure side of the system, the area of the flow passage is increased by using two hydraulic flow passages of two parallel parts, namely the solenoid valve and the check valve, to increase responsiveness.
