VAKUUMUNTERBRECHERVENTIL

摘要

A vacuum breaker valve for use with a toilet such as employed in recreational vehicles. The valve comprises a two-piece plastic valve housing comprising a base member and a cap member sealed to one another. The base member includes a water inlet pipe and an outlet port. A valve element rests on the top of the water inlet pipe. The cap member has an atmospheric opening above the valve element. The base and cap members are formed with cylindrical walls positioned in nested coaxial relationship which define a tortuous path between the inlet and outlet port, which is greater than the actual vertical height of the valve.
