  • the invention relates to a field of machine building and can be used in compressors, pumps and internal combustion engines.
  • a piston machine which has a crankcase with a cylinder fixed on it, in which a piston with a piston rod is located, and cover arranged on the cylinder.
  • a link lever system with a cross head is connected with a crankshaft and has a guide in a lower part of the crankcase (Inventor's Certificate of USSR no. 905499 , FO1B9/00 1978).
  • a disadvantage of the known piston machine is that it does not solve problems of reduction of a waste space that reduces its volume productivity, reducing of hydraulic losses in valves, and also insufficient cooling of the piston of the machine.
  • a piston machine which has a crankcase with a cylinder fixed on it, in which a piston with a piston rod is located, and a cover arranged on the cylinder, suction and pumping valves, two parallel crankshafts located symmetrically relative to an axis of the cylinder and connected with each other with a possibility of rotation in opposite direction, a traverse connected to the piston rod of the piston, two connecting rods each of which is connected with its end hingedly with a corresponding crankshaft, and with another end hingedly with a corresponding end of the traverse, while the piston rod of the piston is connected with the traverse hingedly.
  • the machine is provided with a mechanism of turning of the connecting rods relative to the traverse over different angles.
  • the known piston machine can be configured in a variant of a compressor, a pump or an internal combustion engine (Inventor's Certificate of the USSR no. 1224415 , FO 1B9/02, FO2B 75/32, 1996, the closest prior art).
  • a disadvantage of the known piston machine during its use as a compressor is the presence of a significant waste space and significant hydraulic losses during suction and pumping of a working body due to the location on one cover of the cylinder of suction and pumping valves, increasing a minimal volume between the cover and the piston due to the volume of the valves and reducing areas of flow cross-sections both of suction valves and pumping valves which occupy together the same surface of the cover, which reduces a volume productivity of the piston machine and filling of the cylinder with the working body. Moreover, in the piston machine a sufficient cooling of the piston is not provided.
  • a task which is solved in the invention is a creation of a piston machine which provides a reduction of volume of waste space, a reduction of hydraulic losses during suction and pumping, and a cooling of the machine.
  • the piston machine has a crankcase with a cylinder fixed on it, in which a piston with a piston rod is located, a cover arranged on the cylinder, suction and pumping valves, two parallel crankshafts located symmetrically relative to an axis of a cylinder and connected with one another with a possiblity of rotation in opposite direction, a traverse connected with the piston rod of the piston, two connecting rods each of which is hingedly connected with one end to a corresponding crankshaft, and hingedly connected with another end to a corresponding end of the traverse, and the piston rod of the piston is connected with a traverse hingedly.
  • Distinguishing features of the proposed piston machine from the above mentioned closest prior art is the configuration of the piston with the inner hollow, and a piston rod with a throughgoing longitudinal axial passage, connected with an inner hollow of the piston, arrangement of the suction pipe in the crankcase coaxially with the piston rod which extends into the suction pipe with a possibility of reciprocating movement, a connection of the traverse with the piston rod above an entry to the suction pipe, an arrangement of the suction valves on a front wall of the piston, and of pumping valves on the cover.
  • the configuration of the piston with an inner hollow, of the piston rod with a throughgoing longitudinal axial passage connected with the inner hollow of the piston, arrangement of the suction pipe in the crankcase coaxially to the piston rod which extends into the suction pipe with a possibility of a reciprocating movement, the connection of the traverse with the piston rod above the entry into the suction pipe, the arrangement of suction valves on the front wall of the piston, the arrangement of the pumping valves on the cover of the cylinder allows to create a minimal value of a waste space of the piston machine (a minimum volume remaining between the cover and the piston), which leads to an increase of a volume productivity of the piston machine with a creation of a minimal volume of the waste space and to increase through flow cross-sections in the suction and pumping valves due to the arrangement of the suction valves on the front wall of the piston, and the pumping valves already on another location - on the cover of the cylinder, which leads to a reduction of hydraulic losses in the piston machine, and during movement of the piston from an upper position to
  • connection of the traverse with the piston rod above the entry to the suction pipes provides a movement of the piston rod with the piston.
  • the arrangement of the suction valves on the front wall of the piston, and the pumping valves on the cover of the cylinder allows to reduce the volume of the waste space due to the displacement of the suction valves to another location, and increases throughflow cross sections of the suction and pumping valves again due to the location in the same area of a lower number of the pumping valves and in the same area of the same number of the suction valves, which leads to a reduction of hydraulic losses and increase of volume productivity and filling of the cylinder with the working body.
  • suction valves on the front wall of the piston with a possibility of an arrangement flush with a surface of a front wall of the piston in a closed position, which allows to reduce a volume of a waste space due to the creation of a flat surface of the front wall of the piston.

  • a traverse 29 is connected with the piston rod 4, two connecting rods 10 and 11 each connected with one end hingedly to a corresponding crankshaft 6 or 7, and with another end hingedly connected to a corresponding end of the traverse 29 by means of two ears 25 and 26 with fingers 22 and 23 fixed on them.
  • the piston rod 4 in a zone of connection with the connecting rod has a local square transverse cross-section.
  • the piston rod 4 of the piston 3 is connected with the traverse 29 hingedly by an axle 21.
  • the piston 3 is configured with an inner hollow 12.
  • the piston rod 4 is configured with a throughgoing longitudinal axial passage 13 connected with the inner hollow 12 of the piston 3.
  • a suction pipe 14 is connected in the crankcase 1 coaxially with the piston rod 4, which extends into the suction pipe 14 through a seal 15 with a possibility of a reciprocating movement along guides.
  • the traverse 29 is connected with the piston rod above the entry to the suction pipe 14 when the piston 3 is located in a lower position.
  • the suction pipes 16 are arranged on the front wall 17 of the piston 3, while the pumping valves 18 are located on the cover 5.
  • the pumping valves 18 on the cover 5 are hydraulically connected to a receiver 19, which in turn is connected with a discharge pipe 20.

  • the suction and pumping valves 16 and 18 can be configured as self-acting automatic valves.

  • the piston 3 performs a reciprocating movement in the cylinder 2.
  • the suction valves 16 on the front wall 17 of the piston 3 during its acceleration downwardly are self-opened due to action of inertia forces, thereby remaining on the limiters, and a suction of a working body takes place through the suction pipe 14 and the throughgoing longitudinal axial passage 13 of the piston rod 4 into the inner hollow 12 of the piston 3 and through the openings in the suction valves 16 into the cylinder 2.
