Abstract

The present invention is a poppet comprising a stem and a body, with the body having a plurality of channels extending in a longitudinal direction along the periphery of the body. The channels are gas flow conduits that react to the orientation of the poppet and force the poppet to re-align itself during operation with the centerline of the regulator chamber surrounding the poppet. The plurality of channels greatly reduces the contact between the periphery of the poppet and the regulator body. The present invention further includes a bore beginning at the non­stem end of the body and extending in the longitudinal direction within the body of the poppet. The bore can receive a spring for guiding the poppet. By positioning the spring within the poppet, the spring will have minimal contact with the regulator body. The bore avoids the spring from guiding the poppet by its end and adjusts the poppet's center of gravity toward where the poppet sits on the seat. The bore is also a part of a dead zone volume that traps debris.
