Pump and gas booster using same

Abstract

Provided is a gas buster including: a pump including a cylinder part, a pump housing configured to be in communication with the cylinder part and having a first intake part and a first exhaust part, a piston reciprocably installed at the cylinder part to suck and exhaust water, a first check valve installed at the first intake part to be opened when the piston is moved backward and to be closed when the piston is moved forward, a second check valve installed at the first exhaust part to be opened when the piston is moved forward and to be closed when the piston is moved backward, and a gas supply part installed at the pump housing, and configured to supply a gas into an auxiliary cylinder part and thus to add the gas to the water pumped by the cylinder and the piston; a storage tank which is connected with the first exhaust part of the pump and in which the gas added to the fluid is separated and compressed; and a return pipe configured to connect the storage tank with the first intake part.

1 . A pump comprising:
 a cylinder part;   a pump housing configured to be in communication with the cylinder part and having a first intake part and a first exhaust part;   a piston reciprocably installed at the cylinder part to suck and exhaust an incompressible fluid;   a first check valve installed at the first intake part to be opened when the piston is moved backward and to be closed when the piston is moved forward;   a second check valve installed at the first exhaust part to be opened when the piston is moved forward and to be closed when the piston is moved backward;   an auxiliary cylinder part installed at the pump housing to be in communication with the cylinder part; and   a gas supply part configured to supply a gas to the auxiliary cylinder part so as to add the gas to the incompressible fluid pumped by the piston.   
     
     
         2 . A gas buster comprising:
 a pump having a pump housing in which a cylinder part is provided to add a gas to be compressed to an incompressible fluid in a compression driving part and then to pump them;   a storage tank connected with a first exhaust part of the pump through a supply pipe, and having an internal space in which the gas added to the fluid is separated, and also configured to compress the separated gas;   a return pipe configured to connect the storage tank with a first intake part in communication with the cylinder part of the pump; and   a gas supply part configured to supply the gas to be compressed into the cylinder part for pumping a compressed fluid.   
     
     
         3 . A gas buster comprising:
 a pump comprising a cylinder part, a pump housing configured to be in communication with the cylinder part and having a first intake part and a first exhaust part, a piston reciprocably installed at the cylinder part to suck and exhaust water, a first check valve installed at the first intake part to be opened when the piston is moved backward and to be closed when the piston is moved forward, a second check valve installed at the first exhaust part to be opened when the piston is moved forward and to be closed when the piston is moved backward, and a gas supply part installed at the pump housing, and configured to supply a gas into an auxiliary cylinder part and thus to add the gas to the water pumped by the cylinder and the piston;   a storage tank which is connected with the first exhaust part of the pump and in which the gas added to the fluid is separated and compressed; and   a return pipe configured to connect the storage tank with the first intake part.   
     
     
         4 . The gas buster of  claim 3 , wherein the gas supply part comprises a supply hole connected through a gas supply pipe with a supply part installed at the pump housing to be in communication with the auxiliary cylinder part of the pump housing, and a third check valve installed at the supply hole to be opened when the fluid is sucked by the piston and to be closed when the piston is moved forward and the fluid is exhausted and thus to prevent the gas from flowing back. 
     
     
         5 . The gas buster of  claim 4 , wherein the incompressible gas is a lubricating oil.
