Reservoir tank

摘要

A reservoir tank includes a main portion and a storage chamber disposed in the main portion for storing operating fluid, with the storage chamber being surrounded by a side wall, a ceiling portion and a bottom portion. A float is disposed in the storage chamber and is adapted to move vertically corresponding to the height of the operating fluid level, and a reed switch is operatively associated with the float so as to operate in accordance with the height of the float. A partition member divides the storage chamber into an upper space and a lower space in which the operating fluid and the float are disposed.
