Claim 8:
9. A valve arrangement for a pressurized fluid source, the valve arrangement comprising:
a valve housing comprising an inlet, an outlet, a main fluid channel extending along a longitudinal axis of the valve housing, and a flange extending axially inward into the main fluid channel;
a spool located in the main fluid channel and comprising a first piston, the spool and the first piston are configured to translate together along the longitudinal axis of the valve housing between a closed position and an open position;
a poppet valve located coaxially with the spool, the poppet valve configured to translate along the longitudinal axis of the valve housing;
a regulator spring disposed between the poppet valve and the flange, the regulator spring is configured to bias the poppet valve toward an open position, and the spring is located opposite the flange from the first piston;
wherein the poppet valve is fluidly disconnected from the inlet via the first piston when the spool is in the closed position, and
the poppet valve is fluidly connected with the inlet when the spool is in the open position.
