Abstract

PURPOSE: To lighten concentrated stress caused by injection of working fluid or exciting force of uneven flow by making a connection of a jointed hand at free end of a moving vance and a jointing hand at free end of another moving vane.
CONSTITUTION: A fitting face 2a internally curved is formed on a connected part 2 of a moving vane 1, through which a hemispherical connecting hole 3 is mede. A fitting face 5a internally curved is formed on a connecting part 5 extending from the free end 4a of another moving vane 4. The fitting face 5a is loosely fit on the fitting face 2a of the moving vane 1. The connecting member 6 on the fitting face 5a is in contact with a connecting hole 3. Affecting on the connecting part during rotation, the centrifugal force of each moving vane 1, 4 dissolves the presence of the clearance between the connected part 2 and connecting part 5 and produces damping effect due to its contact friction to lighten the concentrated stress.
