Abstract

The vanes are fixed into the bases of dovetailed shaped, axially parallel slots in the periphery rotor so that a reinforced edge protrudes and presses against the wall of the casing, which forms part of the main tool assembly. The side wall of the dovetail acts as a mechanical stop for the flexibly hinged but relatively still part of the vane protruding from the slot and the pressure of its edge against the casing wall is further restricted by a backing spring within the rotor body and slot.
