PURPOSE: A water pump device is provided to supply necessary flux according to the increment of the power by increasing the pressure area of the main vane. CONSTITUTION: A water pump device comprises a shroud(110), a main vane(115), a sub vane(117) and a spring(120). The shroud is installed inside to be rotated inside a housing(100). The main vane is arranged in the shroud and pressurizes the fluid. The sub vane is extended in the radial direction within the main vane by the centrifugal force. The spring is installed inside the main vane in the radial direction. The spring confines the sub vane in the main vane. An insertion space(122) in which the sub vane slides is formed in the main vane. The main vane and the sub vane are installed in the shroud at a right angle. |
