An mechanical power system provides torque without using a heat engine where fossil-fuel engines have conventionally been used, by replacing the fossil-fuel burning engine with a rotary pneumatic motor and feeding pressure-regulated compressed gas to the rotary pneumatic motor. The rotary pneumatic motor can be used anywhere, and requires preferably compressed nitrogen in a non-liquid state. Automotive, marine and electrical generating applications are adaptable, and auxiliary power is available for emergencies where a supply of compressed gas has been exhausted. A screw-type compressor can be electrically powered to supply compressed gas to the pneumatic motor where tanks of compressed gas have been exhausted. An electrical generating power plant includes an array of solar panels for generating direct current (DC) and a DC/AC converter for converting the DC to alternating current (AC) and outputting a portion of the AC via a power plant output port to supply an AC load.

A shaft extending along a longitudinal axis has fluid channels that increase and decrease pressure in chambers formed between the interior ends of curved pistons and adjacent closed ends of curved chambers within which the pistons reciprocate as the chamber pressure increases and decreases. The chambers and pistons are in separate cylinder block segments extending outward from opposing sides of the shaft. Each segment may have two sides extending along radial planes and joined by a curved outer surface. Pistons may be provided in pairs and have an interior piston end of each piston in a different cavity in different segments. Exterior ends of each piston in a pair of pistons are connected to a piston connector that extends inwardly from a housing so the housing rotates with the pistons.

The invention pertains to a rotary piston internal combustion engine for vehicles, aircraft, vessels or a power generation plant, in particular a planetary piston internal combustion engine. The rotary piston internal combustion engine has a housing including an annular casing, on the sides of which an end-side lateral part and an output-side lateral part are provided and in which a trochoidal trajectory is provided, wherein the casing is traversed by an eccentric shaft mounted in the end-side and output-side lateral parts to the eccentric cam of which a piston rotor is connected, wherein three mutually sealed working chambers are formed in the trochoidal trajectory by rotation of the eccentric shaft by the piston rotor, wherein the piston rotor is provided with sealing elements to seal the working chambers against the trochoidal trajectory and the two lateral parts and an oil inlet and an oil outlet provided in the lateral parts for oil, which serves to lubricate and cool components provided in the piston, into an oil pan, characterized by the fact that the oil outlet can be positioned independently of an installation position of the rotary piston engine relative to the oil pan.

An energy-saving device with functions of air feeding and power generation includes an air feeder, an actuator unit, an air-operated device, a generator, and a power storage unit. The actuator unit includes a mounting base, a cylindrical body received in the mounting base, and an axle body rotatably received in the cylindrical body. The mounting base is connected to the air feeder through an air duct for introduction of gases from the air feeder to the cylindrical body. When the air feeder is activated, the axle body of the actuator unit is rotated to supply high-pressure gases to the air-operated device and simultaneously drive the generator to generate electricity, which is stored in the power storage unit for the air-operated device and/or a power-consuming end, for fullest use of electricity and energy sufficiency.
