Hinge and latching structures associated with a door for a pressure vessel provides a tight and competent seal when the door is in sealed relationship with the opening of the vessel. The latching structure includes coupling structures which provide increased clamping engagement of the door in response to any increased pressure differential developed across the door.

Closure for doors used with small and medium sized pressure vessels

In an unplumbed sterilizer, a measured quantity of liquid is introduced into a partially evacuated chamber in a dump period. The liquid quantity is automatically controlled by closing a valve in the additional conduit upon the occurrence of either (a) the chamber pressure attaining a preset value, or (b) elapsing of a preset time, whichever occurs first.

The disclosed pressurized vessel has a door seal which is pressurized by a steam supply. A diaphragm actuated solenoid valve is connected between the steam supply and the door seal. The diaphragm solenoid valve precludes the door seal from depressurizing unless the pressure within the vessel is within a preselected pressure tolerance. Also, a check valve is provided to preclude the door seal from completely depressurizing if the pressure at the steam supply is interrupted.
