Abstract
The venting mechanism for discharging steam from a sterilizing chamber has a variable effective orifice area controllable in response to decreasing pressure. The throughput of the venting mechanism increases as the pressure decreases, thereby compressing the venting stage of a sterilization cycle without increasing the loss of liquid inherently experienced in sterilizing liquid loads.
