ABSTRACT:
An apparatus for heat treating a work item includes a cover member and a base member on which the cover member is supported. A work space is defined between the base member and the cover member for receiving at least one work item which is positioned therein. A seal member is located between the base member and the cover member for sealing the work space against the entry and exit of gas. A valving system is provided for regulating the entrance and exit of a gas to and from the work space. The valving system is in fluid communication with the work space and includes a relief valve member for allowing the exhaust of the gas from the work space when gas pressure therein exceeds a predetermined limit.
