Diver's suit with pressure chamber - has pipe connecting chamber to housing with window secured to diver's body

摘要

The pressure of the gas inhaled by the diver is approximately equal to the hydrostatic water pressure at the depth where he is working, and the equipment provides an air chamber is supplied his face at least at mouth and nose. This chamber is supplied with compressed air approximately at equal pressure to the hydrostatic. A lightweight watertight housing is provided with a window and secured to the diver's body, and a pipe (23) connects the inside of the housing to the air chamber (10). Thus the housing is only subjected to the slight pressure difference between air and hydrostatic, leaving the diver's hands free and relieved of the need to hold the housing in place.
