ABSTRACT:
A sliding-blade vapor engine has a vortex boiler, condenser, blower and oval-shaped expander and pump chambers with cylindrical expander and pump rotors rotatably mounted eccentrically therein. Each rotor has at least two rectangular blades slidably mounted in slots extending through the cylindrical rotor in mutually perpendicular relation and each blade is independently movable relative to the other in a radial direction. Each blade has a guide element extending from opposed sides and through the opposed end walls of the respective rotor which are slidably received in guide grooves in the respective chamber end walls. The rotors are connected together by shafts in concentric relation whereby rotation of the expander rotor causes simultaneous rotation of the pump rotor and the guide elements traveling in the guide grooves cause the blades to extend and retract radially with their outer ends following the inner periphery of the respective chamber side wall with a constant minimum clearance. The expander rotor is rotated by a working medium from the vortex boiler which causes rotation of the pump rotor. Rotation of the pump rotor draws liquid from a condenser into the pump chamber, compresses it, and discharges it. The discharged liquid enters the vortex boiler, is heated, evaporated, enters the expander chamber, and is discharged back into the condenser. The sliding-blade expander may also be powered by all qualities of geothermal fluids and operate as a motor to drive an electric generator.
