Abstract
A ballcock assembly in which a sheath extends upwardly through the fluid within a reservoir tank to support a valve mechanism above the normal level to which fluid will rise in the reservoir tank. An inlet tube which connects a fluid supply line to the valve mechanism extends through the sheath and is wholly isolated from the fluid within the reservoir tank by the sheath. The outermost lateral dimension of the inlet tube and the innermost lateral dimension of the sheath are such that the inlet tube is completely circumscribed by an air space comprising a passageway that extends the full axial extent of the inlet tube between its effective connection to the valve mechanism and its effective connection to a fluid supply line. The passageway is required to communicate with atmosphere at a level beneath the fluid in the reservoir tank and may also communicate with atmosphere at a level above the normal level to which fluid will rise within the reservoir tank.
