Abstract

A scuba regulator second stage that includes the following improvements: (a) a diaphragm assembly (65) using a pair of generally conical flexible diaphragms (66, 67) facing each other and clamped together about a portion of their periphery, the unclamped peripheral sections (66c, 67c) flexibly spreading apart to function as an exhaust valve; (b) a "detune button" (70) which prevents inadvertent turn-on of the breathable gas supply valve (23) during unattended use of the regulator, and which is automatically disengaged when the user begins to breathe through the regulator; (c) a case configuration in which the breathable gas inlet tube (15) is situated very close to the regulator mouthpiece (17) so as to minimize the torque loading on the teeth of the user as the user's head is turned; (d) a unitary valve configuration in which the entire breathable gas flow valve assembly is removable from the regulator case as an integral unit (40), without the use of tools; (e) a valve poppet (24) configuration which prevents tilting of the poppet when the breathable gas flow control valve is opened; (f) resilient flap (29) and seal members for preventing the entry of contaminants into the valve and diaphragm linkage housing; and (g) in a pneumatic amplification flow control valve, an improved pilot control pin (41) and bleed orifice assembly (44a) having a balanced pressure control chamber (35).
