Transfer compressor and high-pressure gas station using the same

Abstract

The present invention provides a piston type compressor and a high-pressure gas station having the compressor. The compressor includes a piston that divides a cylinder into a compression chamber and an intake chamber, and a check valve is installed in a bearing wall thereof, so that the output pressure is allowed to be compressed to a high pressure even when the intake pressure significantly decreases.

1 . A compressor comprising a piston that divides a cylinder into a compression chamber and an intake chamber,
 wherein the piston includes a check valve allowed to open unidirectionally from the intake chamber to the compression chamber,   the compression chamber has an outlet provided with a check valve allowed to open only in an exit direction,   the intake chamber has an inlet provided with a check valve allowed to open only to the inside of the chamber, and   the piston is connected to an actuator capable of changing internal volumes of both the chambers.   
     
     
         2 . The compressor according to  claim 1 , wherein intake and compression processes are performed simultaneously in a single cycle of the piston, and
 a compression ratio of the compression chamber is allowed to increase multiple times by continuously performing the intake process a plurality of times.   
     
     
         3 . The compressor according to  claim 1 , wherein high pressure gaseous matter is allowed to be filled in an output tank continuously even when a gaseous matter pressure of a supply tank supplied to the intake chamber decreases. 
     
     
         4 . A high-pressure gas station comprising a compressor comprising a piston that divides a cylinder into a compression chamber and an intake chamber,
 wherein the piston includes a check valve allowed to open unidirectionally from the intake chamber to the compression chamber,   the compression chamber has an outlet provided with a check valve allowed to open only in an exit direction,   the intake chamber has an inlet provided with a check valve allowed to open only to the inside of the chamber, and   the piston is connected to an actuator capable of changing internal volumes of both the chambers.   
     
     
         5 . The high-pressure gas station according to  claim 4 , wherein the high-pressure gas station allows continuously transferring high pressure gaseous matter to a storage tank even when a gaseous matter pressure of a transportable tank decreases. 
     
     
         6 . A high-pressure gas station comprising the compressor according to  claim 4 , wherein the high-pressure gas station allows continuously transferring high pressure gaseous matter to a fueling tank for fueling a gas vehicle even when a gaseous matter pressure of the storage tank decreases. 
     
     
         7 . A high-pressure gas station comprising a compressor arranged on a path connecting one or more high-pressure tanks,
 wherein the compressor includes a piston that divides a cylinder into a compression chamber and an intake chamber,   the piston includes a check valve allowed to open unidirectionally from the intake chamber to the compression chamber,   the compression chamber has an outlet provided with a check valve allowed to open only in an exit direction,   the intake chamber has an inlet provided with a check valve allowed to open only to the inside of the chamber,   the piston is connected to an actuator capable of changing internal volumes of both the chambers,   the inlet of the compressor is connected to one of the high-pressure tanks, and   the outlet of the compressor is connected to the other high-pressure tank.   
     
     
         8 . The high-pressure gas station according to  claim 4 , wherein intake and compression processes are performed simultaneously in a single cycle of the piston, and
 a compression ratio of the compression chamber is allowed to increase multiple times by continuously performing the intake process a plurality of times.   
     
     
         9 . The high-pressure gas station according to  claim 4 , wherein high pressure gaseous matter is allowed to be filled in an output tank continuously even when a gaseous matter pressure of a supply tank supplied to the intake chamber decreases.
