Abstract (en)
A machine proposed for use in energy producing industry as an engine, a pump and a compressor. The machine has a crankcase 1, a cylinder 2, and a piston 3 and a piston rod 4, two crankshafts 6 and 7 rotating in opposite directions. An inner hollow 12 of the piston communicates with a throughgoing axial passage 13 of the piston rod 4 located in the crankcase with the possibility of a reciprocating movement in a suction pipe 14; wherein the passage 13 of the piston rod is formed with a diffusor 27 from the side of the hollow 12 of the piston 3 and with a confusor 28 from the side of the suction pipe 14. Pumping valves 18 are arranged on the cover 5 of the cylinder, and suction valves 16 are arranged on the front wall of the piston; wherein the piston rod 16 and the connecting rods 10 and 11 of the crankshaft 6 and 7 are hingedly connected with a traverse 29. The invention provides a reduction of a waste space and reduction of hydraulic losses.
