摘要： 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.

摘要： A water pump apparatus has an impeller mounted on a driven rotational shaft rotatably supported by mutually spaced bearing portions in a body member. In order to lubricate the sliding bearing surfaces between the bearing portions and the rotational shaft, oil seals surrounding the rotational shaft define first and second oil tanks, while a third oil tank is defined between the bearing portions. Spiral oil circulating grooves pump oil from the first and second tanks along the sliding bearing surface to the third tank in order to lubricate the sliding bearing surfaces. Oil passages in the bearing portions permit oil to be returned to the first and second tanks. An annular flange fitted on the rotational shaft fits between the bearing portions to provide axial bearing support for the rotational shaft. Excess oil pressure arising due to heat build up is relieved by a check valve mounted in the body member.
