Abstract: A water supply assembly is provided that includes a support cap, an inlet port and a valve assembly. The valve assembly includes a valve, an outlet port and a float. The support cap has a shape that is configured to cover a reservoir opening into a reservoir of an autoclave, which reservoir opening has a maximum inner diameter that is between 1.5 and 3.0 inches. The float has a shape that is operative to pass through the reservoir opening and into the reservoir when the support cap is placed on the autoclave and is supported by the autoclave in a position to cover the reservoir opening of the autoclave. When the support cap is placed over the reservoir opening, with the float positioned in the reservoir, the inlet port extends outside the reservoir. The float is operative to move from a first position to a second position responsive to a decrease in a water level in the reservoir which causes the valve to open and enable water provided to the inlet port to pass out of the outlet port and into the reservoir.

Abstract: A system for condensing steam is provided that includes a cooling tank and a condensing coil extending into the cooling tank. Coolant from a source of coolant flows into the tank to cool the condensing coil when the temperature of the coolant in the cooling tank exceeds a predetermined value. A drain is in fluid communication with the cooling tank. An air gap assembly is located between the tank and the source of coolant. The air gap assembly includes an opening to atmospheric air and is constructed and arranged to allow coolant to flow out of the opening air vent when there is a predetermined amount of coolant back flowing into the device.
