Abstract: A spa includes a housing forming a vessel, an opening formed in the vessel, a valve fluidly coupled to the opening, a liquid sensor configured to measure an amount of liquid in the vessel, and a controller operatively connected to the valve and the liquid sensor. The controller operates the valve to drain liquid the vessel through the opening, and operates the valve to fill the vessel with liquid from a liquid source when a predetermined amount of liquid has drained from the vessel.

Abstract: A fluid valve including a valve body, a flow control member and a cavitation prevention assembly. The valve body has an inlet, an outlet, a fluid passage communicating fluid therebetween, and means for selectively opening and closing fluid communication between the inlet and the outlet. The flow control member is positioned within the fluid passage and has a central passage through which the fluid advances. The cavitation prevention assembly is positioned within the flow passage and is in flow communication with the inlet and the flow control member. The cavitation prevention assembly controls the pressure of the fluid entering the central passage to a level which is sufficiently low to prevent cavitation of the fluid.

Abstract: A water valve assembly includes a valve body having defined therein (i) an inlet, (ii) an outlet, (iii) a central cavity, and (iv) a component access opening, wherein fluid advancing into the valve body through the inlet must pass through the central cavity before exiting out of the valve body through the outlet, and further wherein the component access opening is configured so that a valve component may be advanced into the central cavity through the component access opening. The water valve assembly further includes a retaining bracket having a retaining portion positioned in relation to the valve body so as to block advancement of the valve component from the central cavity to a location outside of the valve body through the component access opening.

Abstract: A single, rectangular piece of sheet metal is rolled to form a tube having a split seam. A cylindrical piece of rubber is inserted in the cylinder with the ends of the rubber cylinder flush with the ends of the metal tube. The cylinder is squeezed or crimped to close the ends of the piece of sheet metal at the seam and cause the metal tube to grip the rubber, thereby forming an armature.

Abstract: An appliance water valve assembly includes a valve body and an armature which is movable within the valve body. The armature includes an armature tip. The appliance water valve also has a valve seat which includes a valve seat orifice. The valve seat is positioned in cooperation with the armature tip such that the armature tip contacts the valve seat orifice when the appliance water valve is in a closed position and the armature tip is spaced apart from the valve seat orifice when the valve is an open position. The valve seat further includes a cylindrical ring which is positioned around the valve seat orifice. This cylindrical ring protects the valve seat orifice from damage.
