摘要: An improved exhalation valve for a mechanical respirator. The includes valving elements combined in cartridge adapted ready insertion and removal into housing convenient assembly disassembly. A closure member the occludes flow path manner decreasing turbulence flutter. head on is formed by surface of revolution generated curve constant radius, cylindrical skirt axial aligning, non-binding movement with respect to longitudinal ribs central support. operated plunger molded hub gas-operated diaphragm, releaseably locks split intrusive ring hollow stem lost-motion connection.
