Abstract
A valve (10) for a fluid tank, comprising a housing formed with one or more inlet (28) and outlet (20) ports, side walls and a seating wall (14) portion supporting a float-type valve member. The valve member is axially displaceable within the housing responsive to fluid level within the tank, between an uppermost position and a lowermost position, and has a top and a bottom end and a bearing portion facing the seating wall portion of the housing. Either one or both of the seating wall portion of the housing and the bearing portion of the valve member, are fitted with one or more dampening members (46) for diminishing impacting noise of the valve member encountering the housing upon displacement into the lowermost position.
