Antifreeze cap for faucet

摘要

A cap assembly for providing continuous drip to a faucet exposed to freezing temperatures such as a faucet located outside a house. The cap assembly includes a cap member adapted to be mounted over the end of a faucet, which cap member includes a cylindrical wall portion and a closed end portion having an opening therein. The cap assembly includes an internal annular ridge which is adapted to receive a flow disc within the ridge, which flow disc includes an opening which is non-aligned with the opening in the closed end portion of the cap in order to create a dripping action. A rubber washer is positioned in sealing engagement with the internal annular ridge and the flow disc. A filter member is located within the rubber washer such that, upon mounting of the cap assembly over the end portion of a faucet, a continuous dripping flow through the cap assembly may be provided in order to prevent water within the faucet or within piping leading to the faucet from freezing.
