Abstract

An adapter for conveying pressurized gas to an accumulator includes a proximal end to receive the canister and establish a fluid communication passage between an interior thereof and an interior of the accumulator. A distal end is configured to engage the accumulator to establish the fluid communication passage. A housing body includes one of the proximal and distal ends and forms a chamber. An adjuster body is adjustably disposed in the housing body. The adjuster body includes the other of the proximal and distal ends and includes adjuster threads configured to engage housing threads to adjust a position of the adjuster body in the housing body. The adjuster body includes an adjustable shut off valve movably disposed in the chamber to close fluid flow through the passageway wherein moving the adjuster into the housing increases pre-load to increase the force necessary to open the shut off valve.
