Class Information
Number: 415/139
Name: Rotary kinetic fluid motors or pumps > Including thermal expansion joint > Circumferentially spaced nozzle or stator segments
Description: Apparatus comprising a plurality of portions of fluid directing members, said portions extending angularly around and radially spaced from the axis of the runner* support member, said portions having their edges normally spaced from each other whereby dimensional changes due to temperature changes cause such edges to approach or retreat towards or away from each other along the periphery.
