HYDROELECTRIC POWER GENERATOR

摘要

A hydroelectric power generator where a valve mechanism for opening and closing a bypass flow path operates smoothly. In the hydroelectric power generator (1), bypass openings (38) are formed in a separation wall (219), the valve mechanism (9) having a valve body (90) is formed at the center of the openings (38), and a shaft (902) of the valve body (90) penetrates a tube (217) projecting from the separation wall (219). In the valve mechanism (9), a support mechanism (99) is constructed from the tube (217) and the shaft (902). The length over which the tube (217) and the shaft (902) are fitted to each other is kept long even if relative positions of the tube (217) and the shaft (902) vary as the valve body (90) moves, so that the valve body (90) can be stably supported independent of its position.
