Eccentric Pin Positive Locking Device For Hydraulic Turbine Wicket Gates

US Patent:
4210408, Jul 1, 1980
Filed:
Oct 30, 1978
Appl. No.:
5/956093
Inventors:
Donald W. Nace - York PA
Assignee:
Allis-Chalmers Corporation - Milwaukee WI
International Classification:
F03B 318
US Classification:
415163
Abstract:
A hydraulic turbine wicket gate operating assembly including an eccentric pin having a separate hexagonal spacer attached provides a novel means for turning the eccentric pin and fixing it from rotation beyond a desired point. With the arrangement, a single gate operating ring can be utilized to permit all of the gates to move in unison and to provide for the simultaneous closing of each gate against each adjacent gate.
