Abstract: The instant invention is a valve mounted on the above water end of a skin diving snorkel. The valve's opening is in-line with the snorkel's longitudinal axis, thereby providing a substantially straight and unrestricted respiratory flow path. The valve consists of a soft diaphragm mounted on a compound linkage. The linkage is attached to the conduit adjacent the valve opening. A float activates the valve linkage whenever the snorkel starts to descend below the water surface. By the time the valve end of snorkel is underwater, the linkage has moved the diaphragm over and against the valve opening thereby preventing water from entering the snorkel. Conversely, when the valve end of the snorkel is above the water surface, the linkage moves the diaphragm to the side of the snorkel, completely away from the opening and out of the respiratory flow path.

Abstract: Viewing enhancing apparatus for visibility impaired fluid, such as turbid water or a smoke-filled room, includes a fluid-permeable sidewall and a housing defining a confluence cavity having an axis extending between first and second housing ends.
