초록
The present invention includes a ventilator for use in equalizing pressures within and without an enclosure, such as a coldroom or the like. A heated valve assembly is situated within an enclosure wall opening such that it is freely exposed to both environmental and internal fluid air pressures. A fluid impervious wall formed with inlet and outlet ports therethrough is partially covered by inner and outer closure members, both of which are supported and keyed by a common rod or shaft. These closure members are each biased by a common helical spring towar...
