Marine craft drive worm - is conically shaped like meat mincer and located in static housing with large aperture for water input

摘要

The drive worm is conical with the shape of a meat mincer, and beyond the inlet aperture for water the successive windings become ever smaller. In this way, the water pressure within the mincer formation is increased, and the water flows with higher pressure from the smaller outlet aperture, providing the requisite propulsion energy. USE - For marine propulsion.
