HYDRAULIC MACHINE Abstract of the Disclosure The present invention relates to hydraulic machine build- ing. A hydraulic machine, comprising a gate ring linked mecha- nically with at least one servomotor turning said gate ring and with adjustable vanes adapted to provide a given fluid flow rate. The gate ring is fitted with a means for registering it relative to a stationary part. Said stationary part is pro- vided with a stop. The gate ring is fitted with another stop arranged so that with the gate ring in a position correspond- ing to the moment of complete opening of the vanes, said stop faces that mounted on the stationary part. In this case the distance between said stops is minimum as measured along a tangent to the circumference having a centre coincident to that of the gatering, said tangent passing through said stops. The means for registering the gate ring constitute renewable calibrated shims mounted between said stops and having such a size if measured tangentially to said circumference which en- sures such a registering of the rate ring at which an angle of rotation of the vanes corresponds to a given fluid flow rate therethrough. The present invention may prove to be most advantageous when determining the efficiency of Francis and Kaplan hydraulic turbines, pump-turbines and pumps in which the gate or adjust- ing ring is turned by four servomotors.
