Swivel Suit Valve Operation

During it's static phase, medium pressure air enters the swivel suit inflator via the quick connect hose coupling. Air is then prevented from leaking to atmosphere by the upper 'O' ring and is prevented from entering the suit by the lower button 'O' ring. This also eliminates the ingress of water to the suit, if the medium pressure is not connected.

When the button is pressed, the spring compresses and the lower button 'O' ring moves over the venting splines inside the valve body, allowing controllable flowing air into the suit.

When the button is released, the spring moves the button back to its static position, moving the lower botton 'O' ring back into the sealing position in the valve body and preventing medium pressure air entering the suit.
