Abstract

A more compact high energy loss device is provided having a series of uniquely formed multiturn labyrinth assemblies which reduce the pressure of a fluid flowing therethrough. The inlet of the labyrinth assemblies is formed according to a substantially circular configuration to have a predetermined inlet area while the outlet is formed according to a substantially scalloped configuration to provide an outlet area greater than the inlet area. The scalloped configuration of the outlet yields an outlet area which is also greater than if the outlet were of circular configuration. The scalloped outlet configuration also makes the labyrinth assembly less susceptible to circumferential thermal stresses resulting from high temperature fluids passing through the device producing high temperature inlet conditions and low temperature outlet conditions.
