Abstract
A respirator mask for automatically activating an air-saver switch within a regulator by rotation of the regular as the regulator is mounted and dismounted from a facepiece of the mask. The mask includes a facepiece including a regulator engagement region having an aperture and a protrusion proximate the aperture, and a regulator including a regulator body having a facepiece engagement region mateably engageable with the regulator engagement region, a fluid flow path within the regulator body, and a latch within the regulator body, the latch causing obstruction of the fluid flow path when actuated. The latch is engageable with the protrusion, the regulator being rotatable within the facepiece aperture between a first rotational position and a second rotational position, rotation of the regulator within the facepiece aperture from the second to the first rotational position engaging and actuating the latch to obstruct the fluid flow path.
