A pressure regulator for controlling the delivery of gas from a high pressure source to a low pressure device. The pressure regulator includes a distribution body and a pressure adjusting mechanism. The distribution body has a high pressure region and a low pressure region formed therein. The pressure adjusting mechanism controls the transfer of gas from the high pressure region to the low pressure region. The pressure adjusting mechanism includes a piston, an adjusting slug, a seat retainer, a regulator seat, a regulator pin, and a resilient spring.

[ What is claimed is:] [1.] A pressure regulator for controlling the delivery of gas from a high pressure source to a low pressure device, the pressure regulator comprising:a distribution body having a high pressure region and a low pressure region formed therein; anda pressure adjusting mechanism engaging the distribution body for controlling the transfer of gas from the high pressure region to the low pressure region, wherein the pressure adjusting mechanism comprises:a piston having an aperture formed therein;belleville springs extending over a portion of the piston;a retaining mechanism engages the belleville springs and removably retains the pressure adjusting mechanism with respect to the distribution body, the retaining mechanism being a bonnet that removably engages the distribution body;an adjusting slug at least partially extending through the aperture in the piston;a set screw mounted for movement with respect to the piston for changing a position of the adjusting slug with respect to the piston;a regulator seat having an aperture formed therein;a regulator pin engaging the adjusting slug;a resilient spring biasing the regulator pin towards the regulator seat such that the regulator pin substantially seals the aperture in the regulator seat; anda seat retainer having a central aperture and at least one periphery aperture, wherein the regulator pin extends through the central aperture and wherein the regulator seat seals against the seat retainer.
