An apparatus for generating energy by intake and drainage of a fluid includes a reservoir and a pair of receptacles in fluid communication with the reservoir and mounted above the reservoir. Each of the pair of receptacles has a variable volume for holding the fluid. The variable volume is controlled by movable portions. The apparatus includes a lever rotatable about a lever pivot. The lever is coupled at a first side of the lever pivot to the movable portions associated with a first one of the pair of receptacles. The lever is coupled at a second side of the lever pivot to moveable portions associated with a second one of the pair of receptacles. The apparatus includes control valves controlling fluid communication between the pair of receptacles and the reservoir and a controller coupled to the control valves. The apparatus includes a generator coupled to moving portions.

A low-energy and high pressure, hydraulic, pneumatic engine contains: a casing device, two main-cylinder devices, a holder device, two main-crankshaft devices, two recycle-valve devices, two swing-arm devices, two movable-valve devices, two recycle-cylinder devices, two recycle-crankshaft devices, and two umbrella-shaped gear devices. The engine operates without using gasoline or diesel, thus avoiding discharge of harmful substance or gas and pollution. The high pressure gas forces the hydraulic oil without using gasoline or diesel so as to start the engine, and the hydraulic oil recycles and reuses repeatedly, thus obtaining environmental protection. And the high pressure gas forces the hydraulic oil so as to circulate the hydraulic oil, and the communication of the low-energy and high pressure and the low pressure matches with the circulation space of the fluid operation to produce the torque, hence four strokes cycle of intake, compression, combustion and exhaust are not required.
