Definitions

  • the present invention relates to a booster-type gas compressor in which a compressed gas is further compressed by a reciprocating piston.
  • a suction valve 23 is provided at one side of a top wall 22 of a cylinder 21 and a discharge valve 24 is provided at the other side of the top wall 22.
  • a suction chamber 26 having an inlet 25 and a discharge chamber 28 having an outlet 27 respectively.
  • a crank shaft 31 integrally formed with a driving shaft 30 in a crank case 29 is provided under the cylinder 21.
  • the driving shaft 30 is driven by an electric motor 34 in a motor case 33 mounted to a side wall 29a of the crank case 29 so that a gas may pass through.
  • a piston 39 is moved up and down in a cylinder 21 via a piston rod 35 by the crank shaft 31 formed with the driving shaft 30 to compress a gas such as N 2 introduced in a compressing chamber above the piston 36 via the suction valve 23 and to discharge it from the discharge valve 24 and outlet 27.
  • the compressed gas in the crank case 29 Is partially discharged from an air hole 38 of the crank case 29 to produce loss of energy. Leak of a toxic gas causes air pollution.
  • such a reciprocating-piston-type gas compressor comprises a booster-type gas compressor sucking a compressed gas and compressing it to higher pressure
  • the compressing chamber becomes decompression condition in which a atmospheric pressure gas from an air hole 38 of the crank case 29 flows through around the piston 36 to the compressing chamber above the piston 36 and is mixed in a gas from the suction hole 25 to render density lowered.
  • a ventilating hole 39 is formed in the electric motor case 33 or a fan is mounted to the driving shaft 30 to achieve forcing cooling.
  • the electric motor 34 cannot be completely sealed to render noise leaked or dusts, and solid ingredients in external air are likely to remain in the electric motor 34 or motor case 33.
  • An object of the present invention is to provide a booster-type gas compressor comprising a reciprocating piston, pressure difference being reduced between a compressing chamber above the piston and a crank case under the piston thereby preventing wear of each part and unsmoothness of the operation.
  • Fig. 1 shows the first embodiment of a booster-type gas compressor according to the present invention.
  • the basic structure of the booster-type gas compressor is not so different from that in Fig. 4.
  • the same numerals are allotted to the same members. Its description is omitted and only differences are described.
  • Fig. 1 there is no air hole 38 communicating external air and a compressed-gas introducing hole 11 is formed in an electric motor case 36 instead of a ventilating hole.
  • a compressed-gas feeding path 37 is connected to a compressed-gas introducing hole 11 via a bypath conduit 14 comprising a check valve 12 that closes towards the compressed-gas feeding path 37 and opens in an opposite direction and a pressurre regulator 13 such as a pressure-regulating valve or a pressure reducing valve.
  • a compressed gas is fed into a suction chamber 26 and partially introduced into the crank case 29 via the bypath conduit 14 comprising the check valve 12 and the pressure regulator 13, the compressed-gas introducing hole 11. a motor case 33 and a communicating hole 32 to let the inside of the crank case 29 compressed to more than atmospheric pressure.
  • the compressed gas in the compressed-gas feeding path 37 is partially fed into the crank case 29, so that gas pressure in the crank case 29 becomes more than atmospheric pressure different from a known device.
  • difference in pressure between a compressing chamber above a piston 36 in a cylinder 21 and the inside of the crank case 29 becomes smaller than that in a known device, thereby preventing sliding of the piston 36 from lacking smoothness and preventing each of the bearings 41,42 and preventing a seal from reducing their lives or producing looseness caused by unequal force.
  • pressure of a compressed gas in the crank case 29 is regulated, so that pressure difference from a compression chamber above the piston 37 is regulated as soon as possible thereby achieving stable performance.
  • a pressure regulator 15 may be directly joined to the crank case.
  • the pressure regulator 15 may be a reserve tank comprising a pressure-regulating valve and a check valve thereby achieving similar advantage to that in Fig. 1.
  • a compressed-gas feeding path 37 is connected to a compressed-gas introducing hole 11 of a motor case 33 via a bypath conduit 14 comprising a check valve 12 that closes towards the compressed-gas feeding path 37 and opens in an opposite direction.
  • a pressure regulator 13 is provided on the compressed-gas feeding path 37 between the bypath conduit 14 and a suction valve 23 thereby achieving similar advantage to that in Fig. 1.
