Piston-powered engine for operating with water uses water/liquid buoyancy along with the empty weight of a piston-piston rod structure and the generation of a vacuum on the piston

摘要

Vertically aligned cylinder (9)-piston (5) units are located in a water-filled container (1). Each cylinder opens below, has a connecting branch (11) at the top under a cylinder cover and guides a piston rod (4) in the cylinder cover in an air-tight manner. Each piston has a tube (3) fitted flush on the outside.
