A new segmented choke is provided. Designed to reduce thermal stresses created when the fluid temperature fluctuate, this invention is constructed of segmented ceramic members (113-115) fit within a relatively thin-walled retainer (104-106), shrunk fit thereto, thereby allowing the retainer to be more compliant. Shorter, multiple segments used in this invention are also easier to manufacture, can be produced with tighter tolerances, provide easier access thereby reducing maintenance costs and allow for the inclusion of sensors in the individual ceramic segments. This invention also provides improvements in size, manufacturing cost, ease of use and operating efficiency over prior art choke devices.
