Abstract

HYDRO-PROPULSION DEVICE The present invention provides a hydro-propulsion device whereby the device is propelled due to physical actions of an operator of the device. A hydro- propulsion mechanism (100, 200) which is integrated in a hull of the device comprises a drive chamber (102), at least one inlet port (103), an outlet port (104), a shaft (108) with a pusher platform (110), and a collapsible diaphragm or two plates (107). When a force is applied to the pusher platform (110), the shaft (108) slides downward and causes the initially collapsed diaphragm (107) to be radially expanded. The downward motion of the radially expanded diaphragm (107) causes an exertion of pressure force to expel an optimal volume of water within the chamber to the outside environment through the outlet port (104) as a jet of water. The release of the pressurized water to the outside environment resulted in a forward thrust on the device.
