Abstract
A circumferentially complete seal is received in a circumferentially complete groove machined into a surface of a first member forming part of an ionography imaging chamber. The surface of the first member is separated from a surface of a second member of the imaging chamber by a clearance which occasionally connects the interelectrode gap of the imaging chamber with the atmosphere. The seal has an inflatable elastic inner section adjacent to the bottom of the groove and a reciprocable second section which resembles a plunger and is moved from the groove, across the clearance and into sealing engagement with the surface of the second member in response to inflation of the first section. The latter contains a strip-shaped connector which is bolted to the first member to deform a portion of the first section into sealing engagement with the surface at the bottom of the groove. The second section is also a tube which contains a reinforcing insert and has a sealing lip adjacent to the interelectrode gap and sealingly engaging the surface of the second member in response to inflation of the first section. The width of the second section exceeds the width of the clearance and the thickness of the second section is at least twice the width of the clearance. When the first section is deflated, the width of the seal is slightly less than the width of the groove.
