Abstract:
1. An apparatus comprising: (a) a body having each of a first end, an opposed second end and an exterior peripheral surface; (b) a generally closed chamber formed within said body along longitudinal axis thereof; (c) an elongated member positioned along said longitudinal axis of said body and passing through said chamber, said elongated member having each of a first end thereof mounted for rotation between said first end of said body and said chamber, an opposed second end thereof extending outwardly from said second end of said body and a longitudinal bore formed through said elongated member; (d) a plurality of fins disposed within said chamber and radially spaced apart about said longitudinal axis, each of said plurality of fins having a first edge thereof secured on an exterior surface of said elongated member and having an opposed second edge thereof aligned generally parallel with said longitudinal axis, so that plurality of fins rotate with said elongated member; (e) a first fluid communication means secured to said first end of said body in fluid communication with said longitudinal bore of said elongated member, said first fluid communication means is connectable to a source of fluid under pressure for supplying a first portion of the fluid under pressure into said longitudinal bore; (f) a second fluid communication means disposed within said body and having a first end thereof connected in fluid communication to one of said first fluid communication means and the source of the fluid under pressure, said second fluid communication means having an opposed second end thereof being at least in fluid communication with said chamber so as to direct a second portion of the fluid under pressure transversely to a surface of said each fin; and (g) whereby the second portion of the supplied fluid under pressure exits through said second end of said second fluid communication means and contacts said surface of said each fin causing rotation of said elongated member.
