The present invention relates to a silent valve device capable of controlling the flow of a fluid by being connected to a pressure container and at the same time reducing the operation noise of the valve. The existing solenoid valve has problems such as shaking and vibration during operation, malfunction due to a magnetism change in a permanent magnet, collision noise due to magnetism, and a problem where a valve is not closed when any remaining pressure exists so than fine control is not possible. The present invention converts the rotation movement of a cam to a linear movement using the external force of a driving unit so that a valve is opened at the upper dead point of the cam and is returned using the sufficient repulsive power of a compression spring at the lower dead point of the cam. By doing so, the present invention can be used for a product which requires silent operation since operational noise of the valve is prevented and is applicable where fine control for freely opening or closing the values at a desired point of time under pressure is necessary. |
