Title:
VALVE OPENED/CLOSED BY PERMANENT MAGNET
Document Type and Number:
WIPO Patent Application WO/2022/124645
Kind Code:
A1
Abstract:
The present invention relates to a valve opened/closed by a permanent magnet and, more specifically, allows a valve to be opened/closed with low power by generating or dissipating strong repulsive force and attractive force through the meeting or separation of permanent magnets. According to the present invention, fluid rapidly flows out and is blocked by means of the interaction of magnetic forces of the permanent magnets, additional power is not required even if continuous outflow and blocked states are maintained, the valve is driven with low power to provide utility and economic feasibility, which is enabled by a reduction in consumption energy, and a small servo motor and the like are applied as a driving device to miniaturize the exterior shape of the valve, and thus availability and use extensibility of the valve are provided.
