TWO-STAGE GAS REGULATING ASSEMBLY
First Claim
1. A gas regulating assembly for controlling the pressure of gas from a gas reservoir to a pneumatically-operated device comprising:
- a primary housing having a support;
a first stage gas regulator positioned in said primary housing on said support, said first stage gas regulator having an inlet receiving a high pressure gas from the gas reservoir and an outlet providing a regulated gas at an intermediate pressure; and
a second stage gas regulator positioned in said primary housing proximate said outlet of said first stage gas regulator, said second stage gas regulator having an inlet receiving the intermediate regulated gas and an outlet distributing a regulated gas at a controlled pressure to the pneumatically-operated device.

Abstract
A gas regulating assembly controlling the pressure of gas from a gas reservoir to a pneumatically-operated device includes a primary housing surrounding a pair of gas regulators. The gas regulators are aligned in series within the primary housing between an inlet to receive high pressure gas and an outlet for releasing a controlled pressure gas. Each gas regulator includes a sealable valve that defines an input and an output, with each valve including a piston having a cylinder and a rod. A spring is adjacent said piston to force said piston cylinder away from said corresponding inlet, and a shim proximate said spring to adjust the force applied by said spring on said piston cylinder. Each valve allows gas to traverse the corresponding gas regulator until a predetermined pressure is achieved in the respective outlet of the respective gas regulator, at which point the predetermined pressure will close the corresponding valve.

14. A gas regulating assembly for controlling the pressure of gas from a gas reservoir to a pneumatically-operated device comprising:
-
a primary housing having a support;
a proximal gas regulator positioned in said primary housing on said support, said proximal gas regulator having a proximal inlet receiving a high pressure gas from the gas reservoir, a proximal outlet providing a regulated gas at an intermediate pressure, and a proximal valve positioned between said proximal inlet and said proximal outlet allowing gas to traverse the proximal gas regulator until a predetermined pressure is achieved at said proximal outlet to close said proximal valve; and
a distal gas regulator positioned in said primary housing adjacent said proximal outlet of said proximal gas regulator, said distal gas regulator having a distal inlet receiving the intermediate regulated gas, a distal outlet distributing a regulated gas at a controlled pressure to the pneumatically-operated device, and a distal valve positioned between said distal inlet and said distal outlet allowing gas to traverse the distal gas regulator until a predetermined pressure is achieved at said distal outlet to close said proximal valve. - View Dependent Claims (15, 16, 17, 18)
