A scroll compressor is provided and includes a motor housing having a support surface, a fixed scroll fixedly disposable on the motor housing, an orbiting scroll which is operably disposable for fluid-compressive orbital movement relative to the fixed scroll and a removable hydropad removably disposable on the support surface between the orbiting scroll and the support surface.

The present invention describes an external combustion rotary engine, which, due to the separate combustion chamber of the engine, is possible the operation at a lower temperature than those internal combustions, therefore, the engine efficiency is greater. Another characteristic presented by the external combustion rotary engine is that it has concentric expansion chambers and through cams that have a rotor, it is possible to take advantage of the expansion force of the working fluid. The external combustion rotary engine is of closed-cycle operation, so the consumption of additional water is reduced as work fluid since the amount of water within the system is sufficient. Finally, it is worth mentioning that the external combustion rotary engine, thanks to its operation principle, can be applied in the electric power generation field.

The invention relates to a toroidal electric generator (100) comprising a stator (20), which includes a tubular body (21) supporting a plurality of windings (24), and a rotor (30) rotatable within the stator (20) and comprising a support element (31) and a plurality of hydraulic blades (32), each provided with a respective magnet (34) and mounted on the support element (31) integral to it. The toroidal electric generator (100) further comprises an external casing (40) and a plurality of separating elements (51, 52), each separating element being arranged between a respective pair of adjacent windings (24) of the plurality of windings (24) of the stator (20).

An internal combustion engine, configured in the form of an enclosed powered flywheel, operating in a horizontal plane, which functions both as an on-board gyroscope, to stabilize a vehicle from rolling over, and to simultaneously provide vehicular locomotion, through a power train, with the flywheel rotated by at least one fueled piston, of a hosting combustion chamber, internal to the flywheel.

The basic Wotary Engine is a mechanical device consisting of two rotating components. A valve rotating within a valve cavity and a piston continuously rotating through a toroidal cylinder. A wide variety of fuels can be used within the toroidal cylinder to convert solid, liquid, or gaseous fuel, as well as energy sources such water pressure, steam, or air pressure, into rotational mechanical output via a shaft and flywheel which are attached to the pistons.

The Wotary Engine can also be constructed with wire coils closely and sequentially surrounding the toroidal cylinder. As a strongly magnetic piston rotates past the coils, electricity can be conducted off the coils.

Properly timed input of electrical energy to the coils can also be used to impart rotary force to the magnetic piston in the Wotary Engine, thus providing yet another energy source for conversion to rotating mechanical output.
