Abstract: AN COMPRESSOR HAVING A PISTON PERFORMING SIMULTANEOUS FUNCTIONS, which consists of a piston with a top part having a diameter smaller than that of the bottom part. Over the piston, in a reservoir (which has an outlet for compressed air) over the piston cylinder, is located a valve that covers the whole of the top opening of the cylinder. The bottom reservoir, where a crankshaft is located, is connected to the top part of the piston cylinder through passages that allow air to flow from this bottom chamber into the top part of the cylinder. The bottom reservoir has intake valves that open as the piston moves up and close as the piston moves down.

Abstract: A STEAM ENGINE WITH CONVECTION BOILER is provided and is formed by an assembly in which there is present a compressor whose product is mixed with fuel, generating a flame that heats the water that is offered and producing steam. This steam is then transferred to a piston, transforming en in this way the thermal energy into mechanical energy.
