ABSTRACT:
A bubbler includes two molded plastic parts, a main body portion with an internally threaded upper chamber terminating in a valve seat, and a hollow cap with a downwardly extending externally threaded valve stem for engagement with the internally threaded upper chamber of the body portion. Elongated channels extend from the open upper end of the body portion to a position adjacent the valve seat. When the cap is threaded onto the body portion with the end of the valve stem spaced from the valve seat, water flows from the lower chamber of the body portion past the valve seat and upwardly through the channels into the hollow part of the cap and then out through a space between the skirt on the cap and the body portion. When the cap is threaded downwardly to cause the valve stem to engage the valve seat, the bubbler is closed and no water flow takes place through it. Only two parts are required, and water flow adjustment is effected by rotation of the cap to regulate the flow from a full "off" flow to a maximum flow.
