Abstract
A rechargeable water hammer noise suppressor comprising a junction member having a first section including a first connector for coupling the junction member to a water supply; a second section including a second connector for coupling the junction member to a water consuming device; a third section; a small upright sealed chamber containing a volume of air interconnected with the third section; and means for replenishing the air in the chamber.
Claims5
An automatically rechargeable water hammer suppressor adapted to be placed between a pressurized water supply line and a water consuming device comprising an inlet portion, an outlet portion and an intermediate member interconnecting said inlet and outlet portion;
- said intermediate member including a venturi throat, an air inlet passage extending through said intermediate member to said venturi throat, and an air inlet valve in said air inlet passage for drawing air into the water flowing through said venturi throat in said intermediate member;
- and an air chamber extending upward from said intermediate member and connected with said intermediate member downstream of said venturi throat between said venturi throat and said outlet member, for receiving air at increased pressure greater than atmospheric introduced by said venturi throat.
