Abstract

A gas powered engine for use in combination with a pressurized gas source to propel the gas powered engine through a fluid medium such as water comprising an engine housing having a plurality of blades formed on the outer periphery thereof held in fixed spaced relationship to an outer hollow substantially frustum housing by an attachment structure to cooperatively form a fluid flow chamber therebetween, the engine housing comprising a hollow substantially cylindrical housing to operatively house a drive assembly therein, the drive assembly comprising a drive shaft assembly coupled to the attachment structure in fixed relationship relative to the hollow substantially cylindrical housing, having a gas distribution structure mounted thereon, and a cylinder assembly and a swash plate assembly rotatably mounted thereon, the gas distribution structure being operatively disposed between the pressurized gas source and the cylinder assembly to selectively feed and discharge pressurized gas to and from the cylinder assembly, the cylinder assembly comprising a substantially cylindrical cylinder block having a plurality of hollow cylinders formed therein to receive a corresponding plurality of piston assemblies therein for reciprocal movement within the corresponding hollow cylinders for translational movement of the swash plate assembly in response to the pressurized gas feed to the individual piston assemblies to rotate the engine housing to propel the gas powered engine through the water.
