Abstract
A plurality of valves, including ball valves, regulates the flow of a sterilizing agent to and from a sterilizing chamber. Rotary means connected to a ball valve regulates the flow of the sterilizing agent through the valve. Driving means cause the rotary means to rotate, thereby opening or closing the ball valve at predetermined times. A plurality of switches regulate the driving means, and circuit means connected to the switching means regulate the temperature and pressure in the chamber in timed relation with the driving means. Camming means coupled to the driving means operate the switching means in timed relation with the driving means.
