Quick connect pressure reducer/cylinder valve for self-contained breathing apparatus
First Claim
1. A quick connect assembly for a self-contained breathing apparatus (SCBA), comprising:
- an inlet housing configured to be coupled in fluid communication between a pressure vessel and a pressure reducer, the inlet housing having a probe receptacle configured to receive a probe on the pressure vessel;
a latch assembly provided with the inlet housing, the latch assembly configured to move along a movement path between latched and unlatched positions to latch and unlatch, respectively, the probe in the probe receptacle; and
a latch lock assembly provided with the inlet housing, the latch lock assembly moving between locked and unlocked positions to lock and unlock, respectively, the latch assembly, the latch lock assembly including a lock pin in the inlet housing that is movable relative to the inlet housing and the latch assembly, wherein the lock pin extends into the movement path of the latch assembly to engage the latch assembly when in the locked position, and the lock pin being retracted out of the movement path of the latch assembly to not engage the latch assembly when in the unlocked position.
