Abstract: The invention relates to a motor-compressor meant to function as such or in batteries, in various applications, such as mining equipments, rock drills etc. According to the invention, the motor-compressor has a more simple construction by the fact that, inside the base body (1), the motor and compressor enclosures are separated into three enclosures (a, b, c) representing the very same volume, such that the first enclosure (a) which is the driving enclosure, has a driving cylinder provided with a jacket (2), a pair of valves (3 and 4), and an injector (5), the third extreme enclosure (c) is compressing and has a jacket (6) and a pair of valves, an intake valve (7) and a compression valve (8), a piston (9, 10) slide in each of the two extreme enclosures (a, c), the two pistons being coaxially rigidly connected with a common rod (11) provided in the middle enclosure (b).
