Abstract
In a globoid worm type compressor or expander comprising a casing, a globoid worm rotor in the casing and pinions meshing with the worm rotor, provision is made to effect sealing between the thread of the worm and each tooth of the pinions. The arrangement is such that the pinion is mounted on its shaft with the intermediary of a resilient member so that each tooth may be slightly displaced in both circumferential and diametric directions whereby to adapt itself to the thread of the worm to provide gas-tight seal between the tooth and the thread of the worm.
