Hello Mr. Tore,
Page 109 had the following sentence...
"Hence, the Junkers internal and external exhaust casing in the aft torpedo room has a shut and well seated grinding valve plate and a shut external flap valve located in the external Junkers exhaust casing which provides a double water barrier and preventing a water intrusion into the Junkers exhaust and cylinder chamber."
There is no grinding valve plate, so I changed it to...
"Hence, the Junkers internal and external exhaust casing in the aft torpedo room has a water trap located between the external/internal exhaust valves and the compressor’s air intake to impede sea water intrusion into the Junkers exhaust and cylinder chamber.
Does this change meet with your approval?
Regards,
Don_
