Automatic venting means for hot liquid dispensers

摘要

In order to eliminate the risk of back-flow into the water bottle due to gases released in the hot water reservoir 201, the top of the reservoir has a housing 206 for a float 208. The float carries a valve body 209 which normally seals a vent outlet 207, but when gas builds up in the reservoir the float falls allowing the gas to be released. <IMAGE>
