Abstract

Løpehjulsskovler (1, 1') for løpehjulet for en hydraulisk maskin som er utformet på en slik måte at det er mulig å oppnå en større virkningsgrad og å muliggjøre at den hydrauliske maskinen kan drives også i dellastområder uten større begrensninger. Formålet med oppfinnelsen er å oppnå en hydraulisk maskin som har gode kavitasjonsforhold og å fremstille en rotor som er så enkel som mulig uten noen begrensninger ved bruk av små lysåpninger og bearbeidingsmaskiner. For å oppnå disse formål har innløpskantene (4, 4')/eller utløpskantene (5,5') for to tilstøtende løpehjulsskovler (1, 1') avsnittsvis forskjellige forløp.Impeller wheels (1, 1 ') for the impeller of a hydraulic machine designed in such a way that it is possible to achieve a greater efficiency and to enable the hydraulic machine to be operated even in partial load areas without major limitations. The object of the invention is to obtain a hydraulic machine which has good cavitation conditions and to produce a rotor which is as simple as possible without any limitations using small light openings and machining machines. To achieve these purposes, the inlet edges (4, 4 ') / or the outlet edges (5.5') of two adjacent impeller blades (1, 1 ') have different sections in section.
