Abstract: Pelton bucket, Pelton wheel and a method of making and using the Pelton bucket. The Pelton bucket includes at least one exit edge. The at least one exit edge includes one of at least one partially concavely curved portion and at least one straight portion. The method of making provides for arranging at least one exit edge on the Pelton bucket. The method of using provides for causing rotation of a Pelton wheel with a Pelton turbine wherein the Pelton wheel utilizes a plurality of Pelton buckets and wherein the method provides for directing a jet from the Pelton turbine to the Pelton bucket to cause the Pelton wheel to rotate.

Abstract: Pelton buckets generally have flat outlet edges and are only downwardly sloped in the area of the bowl base under certain circumstances. This flat shape naturally limits the optimization possibilities in order to optimize the deflection of the jet in the Pelton bucket with regard to the efficiency of the Pelton turbine. The invention thus relates to a special shape of a Pelton bucket that is accompanied by a substantial gain in efficiency.
