According to an exemplary embodiment of the present invention, since the pressure space of the cylinder is bisected into a vacuum state and a pneumatic state to alternately form a pressure difference, it is possible to generate the kinetic energy of the piston and convert the kinetic energy into other necessary energy. To this end, an exemplary embodiment of the present invention provides an energy conversion apparatus including an energy conversion module including a piston, a piston rod provided on one side of the center of the piston, a cylinder divided into a first pressure space and a second pressure space to be relatively varied with the piston interposed therebetween, and an external air opening/closing part selectively opening and closing the external air to the first pressure space and the second pressure space, respectively; a first bellows containing a fluid therein and provided in the first pressure space to be compressed and expanded; a second bellows containing a fluid therein and provided in the second pressure space to be compressed and expanded; a fluid movement pipe which is positioned outside the cylinder and connects the first bellows and the second bellows to each other to form a closed space, and through which the fluid accommodated therein moves by pressure; a first bellows pressing part for pressing one side of the first bellows; second bellows pressing part for pressing one side of the second bellows; a first motor transmitting a driving force to the first bellows pressing part; and a second motor transmitting a driving force to the second bellows pressing part.

The invention relates to mechanical engineering. The present device for obtaining mechanical work from a non-thermal energy source comprises a cylindrical housing, a rotor, a vacuum chamber, movable elements, and systems for removal and supply of a working fluid. The rotor is provided with blades and is fastened to the power shaft, disposed inside the housing.

A vacuum motor comprising a working plunger, an internal space, in which the working plunger is arranged such that it is mobile in linear direction, a resetting element that exerts, at least for part of the time, a force on the working plunger that acts in the direction of a front side of the internal space, a gas inlet opening for supplying ambient air or a compressed gas into the internal space, and a gas outlet opening for discharging the gas from the internal space. The gas outlet opening is connectable to a negative pressure source, whereby a control plunger is arranged between the working plunger and a rear side of the internal space such as to be mobile in linear direction in the internal space. The control plunger is supported as in a bearing such as to be mobile with respect to the working plunger, and a catch element and/or a spacer is arranged on said working plunger and/or control plunger, whereby the catch element, upon a motion of the working plunger towards the front side of the internal space, transfers the control plunger into the first position, and whereby the catch element or the spacer, upon a motion of the working plunger towards the rear side of the internal space, transfers the control plunger into the second position.

An arrangement includes a combustion-free reciprocating engine having a cylinder closed by a cylinder head and a negative pressure chamber.

A piston is coupled to a crankshaft via a connecting rod. The connecting rod and the crankshaft are integrated in a crankcase of the reciprocating engine.

The cylinder head has an inlet valve and an outlet valve. The vacuum chamber is connectable to a working chamber of the cylinder via the outlet valve, to generate a negative pressure in the working chamber, and to the atmosphere (A) surrounding the reciprocating engine via the inlet valve to generate ambient pressure in the working chamber.

A valve control controls the intake and the exhaust valves such that the piston is moved back and forth by alternately applying ambient pressure and negative pressure

There is always a substantially constant pressure, in a region of the piston facing away from the cylinder head.
