Patent ID: 7004448

Claim:
A trim insert for a choke assembly, the choke assembly including a body, a sleeve insert, and a downstream trim component, the body including an upper body section having an upper body orifice, a discharge channel, and a shoulder, the upper body orifice and the discharge channel in coaxial alignment, the upper body orifice having an orifice diameter, the discharge channel having a channel diameter smaller than the orifice diameter thereby forming the shoulder, the sleeve insert retained within the upper body orifice such that a gap is defined between a second sleeve end and the shoulder, the downstream trim component retained within the discharge channel, the trim insert comprising: a tubular member having a first end, a second end, and a flange intermediate the first end and the second end; the first end positioned within the upper body orifice and having first end inner diameter sufficient to stop flow when a shuttle is in a closed position and a first end outer diameter sufficient to fit within the second sleeve end; the flange having a flange outer diameter sufficient to fit within the upper body orifice and sufficient to retain the tubular member between the second sleeve end and the shoulder; and the second end sealingly retained within the discharge channel and having a second end outer diameter sufficient to fit within the discharge channel and sufficient to retain the tubular member against the adjacent downstream trim component.
