  • Vacuum unit for steam sterilizer
    Patent number: 8062002
    Abstract: In a vacuum unit for use in drawing a vacuum on a steam sterilizer, a pump circulates water through an ejector and a reservoir. Fresh water is injected at the pump inlet to maintain a low temperature in the ejector so that it can operate efficiently. Excess water is taken from a location adjacent the bottom of the reservoir through an internal dip tube, and passed through a U-shaped conduit that serves as a condensate trap. To maintain the water discharge temperature below a predetermined level, fresh water is injected into the U-shaped conduit through a valve controlled by a temperature sensor downstream from the water injection point.
