Abstract
An elliptical steam sterilizer includes an elliptically shaped inner shell (12) and an elliptically shaped outer jacket (14). The inner shell (12) and outer jacket (14) are supported on opposite ends by an end plate (16) and a back head (20). The elliptical shape of the sterilizer distributes the forces caused by pressurization and evacuation of the inner shell (12) in a beneficial manner which eliminates the need for expensive reinforcement of the inner shell and outer jacket (14). The elliptical shape, which is oriented with its major axis (Y) positioned vertically and its minor axis (X) positioned horizontally, provides greater capacity than a cylindrical sterilizer with the same size footprint.
