ABSTRACT:
A sealed type hydraulic reservoir including a casing for storing brake fluid therein, a cap member detachably mounted on the casing and an elastic diaphragm member dividing the casing into upper and lower chambers. The lower chamber is defined by the diaphragm member and the liquid surface, and the pressure in the lower chamber is always maintained at the level of atmospheric pressure by two check valves, one for allowing the air flow from the upper to the lower chamber when the pressure in the lower chamber drops below the atmospheric level and the other for allowing the air flow from the lower to upper chamber when the pressure in the lower chamber rises above the atmospheric level.
