Definitions
- the present invention relates to a compressor for transferring high-pressure gas in which the fluctuation range of the inlet pressure is large and the outlet pressure becomes ultra-high pressure, and a high-pressure gas station using the compressor.
- Patent No. 6160876 "Honeycomb structure in which the honeycomb core is arranged parallel to the panel surface and a method for manufacturing the same" discloses a method for manufacturing a high-pressure gas tank using the honeycomb structure.
- Japanese Patent No. 6160876 also presents the idea of an ultra-high pressure gas station.
- High-pressure gas tanks for transportation and storage are indispensable for the operation and management of high-pressure gas stations.
- Patent No. 6160876 presents a honeycomb-structured gas tank as a high-pressure gas tank for transportation and storage. The evaluation of the honeycomb structure gas tank is proved by the hydraulic test.
- Further essential to the high pressure gas station is a compressor that transfers high pressure gas from the transport gas tank to the storage gas tank.
- High-pressure compressors are also presented in Japanese Patent No. 6160876, but the mechanical structure of high-pressure compressors is not shown.
- a multi-stage piston type compressor is used for the high pressure compressor.
- the multi-stage piston method is a combination of two sets of pistons. The first piston and the second piston are connected in series.
- the compression ratio of the initial piston is approximately "20: 1".
- the compression ratio of the second piston is approximately "2: 1".
- the multi-stage piston can obtain a total compression ratio of approximately "40: 1".
- the reason why the compression ratio of the second piston cannot be increased is as follows.
- a high-pressure gas of 4.0 MPa is produced from a 0.1 MPa gas by a multi-stage compressor.
- the compressed high-pressure gas is stored in a high-pressure gas tank.
- the cylinder volume of the first compressor is assumed to be 1000 cc, and the compression ratio is 20: 1.
- the gas compressed by the first (first) compressor enters the cylinder of the second compressor. In this case, it is discharged from the first compressor.
- the capacity and pressure of the compressed gas are 50cc and 2.0MPa.
- the cylinder volume of the second compressor is 100 cc
- the pressure inside the second cylinder is 1.0 MPa. Therefore, it is meaningless that the volume of the second compressor exceeds 50 cc.
- the compression ratio of the second compressor is 2: 1, the capacities and pressures of the compressed gas produced by the second compressor are 25cc and 4.0MPa. It is not realistic to increase the compression ratio with such a small compressor.
- FIG. 12 is a conceptual diagram of a high-pressure gas station assumed from Japanese Patent No. 6160876.
- the high-pressure gas station includes a transport tank 20 for movement, a connection valve 21 attached to and detached from the tank 20, a transfer line 22 having a connection valve 21 at the end, and a 3-way valve 23 provided in the middle of the transfer line 22.
- a bypass line 24 switched by the 3-way valve 23 and a storage gas high pressure line 26 via a transfer compressor 36 are provided.
- the storage gas high pressure line 26 is connected to the storage tank 27, the pressure line 29 is connected to the outlet of the storage tank 27 via the pressurizing compressor 37, the refueling tank 30 is connected to the pressurizing line 29, and further.
- a refueling valve 32 is provided at the outlet of the refueling tank 30 via a high pressure refueling line 31. This makes it possible to refuel the gas vehicle 33.
- a management building 34 and a site 35 are provided.
- the concept of the high pressure gas station in FIG. 12 is as follows. (1) It is assumed that the initial pressure of the transport tank 20 is 60 MPa. It is assumed that the pressure of the storage tank 27 is 60 MPa. It is assumed that the pressure of the refueling tank 30 is 80 MPa. It is assumed that the compression ratio of the transfer compressor 36 is 20: 1. It is assumed that the compression ratio of the pressurizing compressor 37 is 20: 1. (2) In the high-pressure gas station of FIG. 12, there are two methods for transferring high-pressure gas of 60 MPa from the transport tank 20 to the storage tank 27. The 60 MPa high pressure gas filled in the transport tank 20 is transported from the gas supply base.
- A One is a transport tank 20, a connection valve 21, a transfer line 22, a 3-way valve 23, a bypass line 24, and a line directly sent from the storage gas high pressure line 26 to the storage tank 27.
- B Another is a transport tank 20, a connection valve 21, a transfer line 22, a 3-way valve 23, a transfer compressor 36, and a line from the storage gas high pressure line 26 to the storage tank 27.
- the transfer compressor 36 pressurizes and transfers the high-pressure gas transported in the transport tank 20 to the storage tank 27.
- the pressure of the storage tank 27 is 60 MPa.
- the transfer line 22, the 3-way valve 23, the bypass line 24, the transfer compressor 36, the storage gas high pressure line 26, and the storage tank 27 are installed underground.
- the 60 MPa high-pressure gas stored in the storage tank 27 is pressurized and transferred to the 80 MPa refueling tank 30 by the pressurizing compressor 37 through the pressurizing line 29.
- the pressurizing compressor 37, the pressurizing line 29, and the refueling tank 30 are installed underground.
- the 80 MPa high-pressure gas stored in the refueling tank 30 is refueled to the gas vehicle 33 by the refueling valve 32 through the refueling high-pressure line 31.
- the transportation tank 20 is a transportation gas tank from the gas supply base to the gas station.
- the transport tank 20 is made of a honeycomb structure high pressure tank assumed from Japanese Patent No. 6160876.
- the initial pressure of the transport tank 20 is assumed to be 60 MPa.
- connection valve 21 is an on-off valve to the transfer line 22.
- the transfer line 22 is connected to the 3-way valve 23.
- the 3-way valve 23 is a switching valve for the bypass line 24 and the transfer compressor 36.
- the bypass line 24 and the transfer compressor 36 are connected to the storage gas high pressure line 26.
- the bypass line 24 coming out of the 3-way valve 23 is connected in the middle of the storage gas high pressure line 26.
- the gas in the transport tank 20 flows directly to the storage gas high pressure line 26.
- the transfer compressor 36 is connected to the storage gas high pressure line 26.
- the storage gas high pressure line 26 is connected to the storage tank 27.
- the transfer compressor 36 transfers the high-pressure gas of the transport tank 20 to the storage tank 27.
- the storage tank 27 is a gas tank that stores high-pressure gas transported from the gas supply base by the transportation tank 20. Like the transportation tank 20, the storage tank 27 is made of a honeycomb structure high pressure tank assumed from Japanese Patent No. 6160876.
- the pressurizing compressor 37 is connected to the storage tank 27 by a high pressure pipeline.
- the pressurizing compressor 37 pressurizes the high-pressure gas in the storage tank 27 to 80 MPa.
- the high pressure gas pressurized to 80 MPa is sent to the refueling tank 30 through the pressurizing line 29.
- the pressurizing line 29 is a high pressure pipeline that can withstand a high pressure of 80 MPa or more.
- the refueling tank 30 is an ultra-high pressure gas tank assumed to be 80 MPa.
- the refueling tank 30 stores high-pressure gas for refueling the gas vehicle 33.
- the refueling tank 30 is made of a honeycomb structure high pressure tank assumed from Japanese Patent No. 6160876.
- the refueling high pressure line 31 is connected to the refueling tank 30.
- the refueling high-pressure line 31 is an ultra-high pressure gas pipeline that transfers the high-pressure gas stored in the refueling tank 30 to the refueling valve 32.
- the refueling valve 32 is a pressure adjusting valve that refuels the gas vehicle 33 with high-pressure gas.
- the gas vehicle 33 is a vehicle that has an in-vehicle gas tank such as natural gas or hydrogen gas.
- the gas tank of the gas vehicle 33 is assumed to be 60 MPa.
- the management building 34 and the site 35 are the management building and the site of the gas station.
- the high pressure gas station system shown in FIG. 12 seems to work well. However, it does not fully realize the function with the conventional technique. The reason is as follows. (1) In order to refuel the in-vehicle gas tank of the gas vehicle 33 with high pressure gas of 60 MPa, it is desirable to maintain the internal pressure of the refueling tank 30 at 80 MPa. (2) The ultra-high pressure gas in the refueling tank 30 is supplied from the storage tank 27 by the pressurizing compressor 37. It is assumed that the pressurizing compressor 37 is a piston type compressor having a compression ratio of 20: 1 in the prior art.
- the pressurizing compressor 37 can easily produce 80 MPa ultra-high pressure gas from 60 MPa high pressure gas, so that 80 MPa gas is supplied to the refueling tank 30. It's easy to do.
- a high pressure gas of 60 MPa and 1000 cc becomes an ultra high pressure gas of 80 MPa and 750 cc.
- the compression ratio is 1.33: 1.0.
- the compression ratio of the pressurizing compressor 37 is larger than this value.
- the high pressure gas is continuously supplied from the storage tank 27 to the refueling tank 30, the internal pressure of the storage tank 27 gradually decreases.
- the pressurizing compressor 37 cannot supply the ultra-high pressure gas of 80 MPa to the refueling tank 30. That is, the high-pressure gas of 4.0 MPa or less remaining in the storage tank 27 becomes completely dead stock. 4.0 MPa is about 40 atmospheres.
- a multi-stage piston with a compression ratio of 40: 1 is used for the compressor, it can be used until the pressure of the storage tank 27 is reduced to 2.0 MPa.
- a multi-stage piston is a combination of a first piston and a second piston. When the pressure of the storage tank 27 is 4.0 MPa or more, the second piston of the multi-stage piston becomes a useless obstacle.
- the relationship between the transport tank 20 and the storage tank 27 is also the same. To simplify the calculation, it is assumed that the internal pressure of the transport tank 20 is 60 MPa and the internal pressure of the storage tank 27 is zero. Then, it is assumed that the volume of the transportation tank 20 is 3000 liters, and the volume of the storage tank 27 is also 3000 liters. Simply put, it is assumed that 3000 liters, 60 MPa high pressure gas is transferred from a transport tank to an empty underground tank. If this transfer is done in the prior art, it would be: (1) The transportation tank 20 is transported from the gas supply base to the gas station.
- the transportation tank 20 is connected to the transfer line 22, the 3-way valve 23, the bypass line 24, the transfer compressor 36, the storage gas high pressure line 26, and the storage tank 27 by the connection valve 21.
- the connection valve 21 When the connection valve 21 is opened, the high pressure gas of 60 MPa moves through the transfer line 22 to the 3-way valve 23.
- the 3-way valve 23 When the 3-way valve 23 is opened to the bypass line 24, the high pressure gas of 60 MPa flows into the storage tank 27 through the bypass line 24 and the storage gas high pressure line 26.
- the high-pressure gas of the transportation tank 20 stops flowing when the internal pressure of the storage tank 27 reaches 30 MPa.
- the 30 MPa high-pressure gas remaining in the transport tank 20 is left in the transport tank 20 as dead stock.
- the pressure inside the storage tank 27 stays at 30MPa and does not reach 60MPa. That is, it is not possible to transport the high pressure gas in the transport tank to the underground tank simply by opening the bypass valve.
- the prior art piston compressor challenges this challenge. Even if the inlet pressure fluctuates greatly, the piston type compressor is effective.
- the transfer compressor 36 is a conventional piston type compressor having a compression ratio of 20: 1.
- the transfer compressor 36 can easily produce 60 MPa high-pressure gas from 30 MPa high-pressure gas, when the internal pressure of the transport tank 20 is 30 MPa, 30 MPa high-pressure gas is transferred to the storage tank 27. It's easy.
- the high pressure gas of 30MPa and 1000cc becomes the high pressure gas of 60MPa and 500cc.
- the compression ratio is 2: 1.
- the compression ratio of the transfer compressor 36 is larger than this value.
- the invention described here is a newly invented compressor for transferring high-pressure gas, and the compressor realizes the function of a high-pressure gas station.
- the newly invented compressor is a compressor that realizes the function of a multi-stage piston with a single piston.
- the piston type compressor of the prior art is insufficient to realize the high pressure gas station explained by the "problem to be solved by the invention".
- a new type of compressor is needed.
- the prior art piston scheme is not completely useless. It is quite effective where the fluctuation range of the inlet pressure is large and the outlet pressure becomes high pressure. If the compressor of the present invention can obtain the function of a multi-stage piston without a second piston, the above problem can be solved. That is, if a compressor having a multi-stage piston type function can be invented with one piston, the high-pressure gas station shown in FIG. 12 can be realized.
- Two pressurizing chambers are required to obtain the function of a multi-stage compressor with one piston. It looks impossible, but it's not impossible.
- a two-stroke engine two-stroke period
- has a pressurizing chamber behind the engine piston In the case of pistons and cylinders, they are called double-acting cylinders.
- the present invention uses a linear actuator (linear actuator) or a linear motor to move the piston.
- linear actuators are inferior to rapid pressurization.
- refueling by the high-pressure gas station is refueled by the pressure difference between the high-pressure gas of the gas station and the in-vehicle tank of the gas vehicle, so that the transfer compressor does not need to rapidly pressurize the high-pressure gas. Therefore, the capacity required for the compressor in FIG. 1 is not immediate effect but continuous power.
- Linear actuators and linear motors are excellent in the convenience of drive devices. The simplicity of the drive makes it easy to enhance the structural strength.
- the compressor according to the present invention has a piston that divides the inside of the cylinder into a compression chamber and an intake chamber, and the piston is provided with a check valve that can be opened only in the direction from the intake chamber to the compression chamber.
- a check valve that can be opened only in the outlet direction is provided at the outlet of the chamber, and a check valve that can be opened only into the chamber is provided at the inlet of the intake chamber, and the internal volumes of both chambers are variable for the piston. It is characterized by connecting an actuator.
- the compressor is characterized in that the output tank can be continuously filled with high-pressure gas even if the gas pressure of the supply tank supplied to the intake chamber is reduced.
- the high-pressure gas station according to the present invention is a high-pressure gas station equipped with a compressor having the above configuration. Further, in this case, even if the gas pressure of the transportation tank is reduced, the high-pressure gas can be continuously transferred to the storage tank. Further, even if the gas pressure of the storage tank is reduced, the high-pressure gas can be continuously transferred to the refueling tank for the gas vehicle.
- a compressor is placed in the path connecting the pair of high-pressure tanks, and this compressor has a piston that divides the inside of the cylinder into a compression chamber and an intake chamber, and the piston has a check valve that can be opened only in the direction from the intake chamber to the compression chamber.
- the outlet of the compression chamber is provided with a check valve that can be opened only in the outlet direction

Abstract
Description
(2)最初(1番目)のコンプレッサで圧縮されたガスは、2番目のコンプレッサのシリンダに入る。この場合、1番目のコンプレッサから排出される。圧縮されたガスの容量と圧力は、50ccと2.0MPaである。2番目のコンプレッサのシリンダ容積を100ccとすると、2番目のシリンダ内部の圧力は1.0MPaになる。従って、2番目のコンプレッサの容積が50ccを超えることは意味がない。
(3)2番目のコンプレッサの圧縮比が2:1であるとき、2番目のコンプレッサによって作られた圧縮ガスの容量と圧力は、25ccと4.0MPaである。このような小さいコンプレッサで圧縮比を拡大することは現実的ではない。
(1)輸送用タンク20の初期圧力を60MPaと仮定する。保管タンク27の圧力を60MPaと仮定する。給油用タンク30の圧力を80MPaと仮定する。移送用コンプレッサ36の圧縮比を20:1と仮定する。加圧用コンプレッサ37の圧縮比を20:1と仮定する。
(2)図12の高圧ガスステーションにおいて、輸送用タンク20から保管タンク27まで60MPaの高圧ガスを移送には2つの方法がある。輸送用タンク20に充填された60MPaの高圧ガスはガスの供給ベースから輸送される。
(a)ひとつは輸送用タンク20、接続バルブ21、移送ライン22、3-ウェイバルブ23、バイパスライン24、および保管ガス高圧ライン26から保管タンク27へ直送されるラインである。
(b)別のひとつは輸送用タンク20、接続バルブ21、移送ライン22、3-ウェイバルブ23、移送用コンプレッサ36、および保管ガス高圧ライン26から保管タンク27へのラインである。
(3)移送用コンプレッサ36は輸送用タンク20で輸送されてきた高圧ガスを保管タンク27に加圧して移送する。保管タンク27の圧力は60MPaである。
(4)移送ライン22、3-ウェイバルブ23、バイパスライン24、移送用コンプレッサ36、保管ガス高圧ライン26、および保管タンク27は地下に設置される。
(5)保管タンク27に格納されている60MPaの高圧ガスは、加圧ライン29を通って加圧用コンプレッサ37によって80MPaの給油用タンク30に加圧されて移送される。
(6)加圧用コンプレッサ37、加圧ライン29、および給油用タンク30は地下に設置される。
(7)給油用タンク30に収納された80MPaの高圧ガスは、給油用高圧ライン31を通して給油バルブ32によってガス自動車33に給油される。
(1)ガス自動車33の車載ガスタンクに60MPaの高圧ガスを給油するため、給油用タンク30の内部圧力は80MPaを維持することが望ましい。
(2)給油用タンク30の超高圧ガスは加圧用コンプレッサ37によって保管タンク27から供給される。加圧用コンプレッサ37は従来技術における圧縮比20:1のピストン式コンプレッサであると仮定する。
(3)保管タンク27の内部の圧力が60MPaであるとき、加圧用コンプレッサ37は60MPaの高圧ガスから80MPaの超高圧ガスを容易に作ることができるので、80MPaのガスを給油用タンク30に供給するのは容易である。
(4)例えば、60MPa、1000ccの高圧ガスは80MPa、750ccの超高圧ガスになる。圧縮比は1.33:1.0である。加圧用コンプレッサ37の圧縮比はこの値より大きい。
(5)しかし、保管タンク27から高圧のガスを給油用タンク30に供給し続けるとき、保管タンク27の内部圧力は徐々に減少する。保管タンク27の圧力が4.0MPaかそれ以下になると、加圧用コンプレッサ37は80MPaの超高圧ガスを給油用タンク30に供給することができなくなる。つまり、保管タンク27に残っている4.0MPa以下の高圧ガスは完全にデッドストックとなる。4.0MPaはおよそ40気圧である。
(6)もしコンプレッサに圧縮比40:1の多段階ピストンを使用するならば、保管タンク27の圧力が2.0MPaに減少するまで使用することが可能である。しかし、多段階ピストンは1番目のピストンと2番目のピストンの組み合わせである。保管タンク27の圧力が4.0MPa以上あるとき、多段階ピストンの2番目のピストンは役に立たない障害物となる。
(1)輸送用タンク20はガスの供給ベースからガスステーションまで運ばれる。
(2)輸送用タンク20は接続バルブ21によって移送ライン22、3-ウェイバルブ23、バイパスライン24、移送用コンプレッサ36、保管ガス高圧ライン26、および保管タンク27に接続される。
(3)接続バルブ21が開かれるとき、60MPaの高圧ガスは移送ライン22を通って3-ウェイバルブ23まで移動する。
(4)3-ウェイバルブ23がバイパスライン24に開かれるとき、60MPaの高圧ガスはバイパスライン24と保管ガス高圧ライン26を通して保管タンク27に流入する。
(5)輸送用タンク20と保管タンク27の容積は同じなので、輸送用タンク20の高圧ガスは保管タンク27の内部圧力が30MPaになると流れるのを止める。
(6)輸送用タンク20に残った30MPaの高圧ガスはデッドストックとして輸送用タンク20に残される。保管タンク27の内部の圧力は、30MPaに止まって、60MPaに達しない。つまり、単にバイパス弁を開くことによって輸送タンクの高圧ガスを地下タンクに輸送することは不可能である。
(1)移送用コンプレッサ36は圧縮比20:1の従来技術のピストン式コンプレッサであると仮定する。
(2)移送用コンプレッサ36は30MPaの高圧ガスから60MPaの高圧ガスを容易に作ることができるので、輸送用タンク20の内部圧力が30MPaであるとき、30MPaの高圧ガスを保管タンク27に移送することは簡単である。30MPa、1000ccの高圧ガスは60MPa、500ccの高圧ガスになる。圧縮比は2:1である。移送用コンプレッサ36の圧縮比はこの値より大きい。
(3)しかし、輸送用タンク20から高圧ガスを保管タンク27に供給し続けるとき、輸送用タンク20の内部圧力は徐々に減少する。輸送用タンク20の圧力が3.0MPaかそれ以下になると、移送用コンプレッサ36は60MPaの高圧ガスを保管タンク27に供給することができなくなる。
(4)つまり、輸送用タンク20に残っている3.0MPa以下の高圧のガスは完全デッドストックとなる。3.0MPaはおよそ30気圧である。
(5)もしコンプレッサに圧縮比40:1の多段階ピストンを使用するならば、輸送用タンク20の圧力が1.50MPaに減少するまで使用することは可能である。しかしながら、多段階ピストンは2個のピストンの組み合わせである。輸送用タンク20の圧力が3.0MPa以上あるとき、多段階ピストンの2番目のピストンは役に立たない障害物となる。

(1) 輸送用タンク20の初期内部圧力を60MPaと仮定する。保管タンク27の内部圧力を60MPaと仮定する。給油用タンク30の内部圧力を80MPaと仮定する。移送用コンプレッサ25の圧縮比を20:1と仮定する。加圧用コンプレッサ28の圧縮比を20:1と仮定する。
(2) 図11における高圧ガスステーションにおいて、輸送用タンク20から保管タンク27まで60MPaの高圧ガスを移送するには2つのラインがある。60MPaの高圧ガスはガス供給ベースから運ばれるとする。
(a)ひとつは輸送用タンク20、接続バルブ21、移送ライン22、3-ウェイバルブ23、バイパスライン24、および保管ガス高圧ライン26から保管タンク27へのラインである。
(b)別のひとつは輸送用タンク20、接続バルブ21、移送ライン22、3-ウェイバルブ23、移送用コンプレッサ25、および保管ガス高圧ライン26から保管タンク27へのラインである。
(3) 移送用コンプレッサ25は輸送用タンク20のガスを保管タンク27に加圧して移送する。保管タンク27の圧力は60MPaである。
(4) 移送ライン22、3-ウェイバルブ23、バイパスライン24、移送用コンプレッサ25、保管ガス高圧ライン26、および保管タンク27は地下に設置される。
(5) 保管タンク27に格納された60MPaのガスは、加圧ライン29を通って80MPaの給油用タンク30に加圧用コンプレッサ28によって加圧され移送される。
(6) 加圧用コンプレッサ28、加圧ライン29、および給油用タンク30は地下に設置される。
(7) 給油用タンク30に格納された80MPaの高圧ガスは給油用高圧ライン31を通して給油バルブ32からガス自動車33に給油される。
(1) ガス自動車33の車載ガスタンクに60MPaの高圧ガスに給油するためには、給油用タンク30の内部圧力が80MPaを維持することが望ましい。
(2) 給油用タンク30のガスは加圧用コンプレッサ28によって保管タンク27から供給される。加圧用コンプレッサ28は図1の複機能コンプレッサ1である。本発明による複機能コンプレッサ1はピストン式コンプレッサである。その圧縮比を20:1と仮定する。
(3) 保管タンク27の内部圧力が60MPaであるとき、加圧用コンプレッサ28は60MPaの高圧ガスから80MPaの超高圧ガスを容易に作ることができるので、80MPaのガスを給油用タンク30に供給することは簡単である。
(4) 1000ccと60MPaの高圧のガスは750ccと80MPaの超高圧ガスになる。その場合の圧縮比はわずか「1.33:1」である。
(5) 保管タンク27からのガスを給油用タンク30に供給し続けるとき、保管タンク27の内部圧力は徐々に減少する。
(6) 従来技術では、保管タンク27の圧力が4.0MPa以下になった場合、単一のピストン式コンプレッサでは80MPaの超高圧ガスを給油用タンク30に供給することは不可能である。つまり、保管タンク27に残っている4.0MPa以下の高圧ガスは完全にデッドストックとなる。
(7) 従来技術には、圧縮比が40:1である多段階ピストン方式のコンプレッサが存在する。ガス給油システムに多段階ピストンコンプレッサを使用するとき、保管タンク27の圧力が2.0MPaに減少するまで、コンプレッサは保管タンク27のガスを80MPaに圧縮することが可能である。しかしながら、多段階ピストンは2個のピストンの組み合わせである。保管タンク27の圧力が2.0MPa以上であるとき、多段階ピストンの2番目のピストンは全く役に立たない障害物となる。
(8) 本発明では、移送用コンプレッサ25と加圧用コンプレッサ28は図1で示された複機能コンプレッサ1である。複機能コンプレッサ1は、2度吸気をすることによって排気の圧力を2倍にすることが可能である。吸気の回数に制限はない。従って、保管タンク27の圧力が4.0MPa以下になっても、加圧用コンプレッサ28は80MPaのガスを給油用タンク30に供給しつづけることが可能である。複機能コンプレッサ1は、ピストン3を2回動かすことで、2.0MPaの圧力を80MPaに圧縮することが可能である。さらに、複機能コンプレッサ1は、ピストン3を3回動かすことによって、1.3MPaの圧力を80MPaに加圧することが可能である。複機能コンプレッサ1は2個のピストンの組み合わせではないので、ガス給油システムに全く障害はない。
(1) 輸送用タンク20はガス供給ベースからガスステーションに輸送される。
(2) 輸送用タンク20は接続バルブ21によって移送ライン22、3-ウェイバルブ23、バイパスライン24、移送用コンプレッサ25、保管ガス高圧ライン26、および保管タンク27に接続される。
(3) 接続バルブ21が開かれると、60MPaの高圧のガスは移送ライン22を通って3-ウェイバルブ23にまで動いていく。
(4) 3-ウェイバルブ23がバイパスライン24に向かって開かれるとき、60MPaの高圧のガスはバイパスライン24と保管ガス高圧ライン26を通して保管タンク27に流入する。
(5) 輸送用タンク20と保管タンク27の容積が同じと仮定してあるので、輸送用タンク20の高圧ガスは、保管タンク27の内部圧力が30MPaになると流入を停止する。
(6) 30MPaの高圧のガスはデッドストックとして輸送用タンク20に残される。保管タンク27の内部圧力は、30MPaで停止して、60MPaに達しない。つまり単にバイパス弁を開くことによってのみでは、輸送用タンクの全ての高圧ガスを地下タンクに移送することは不可能である。
(1) 移送用コンプレッサ25を図1における複機能コンプレッサ1であると仮定する。また、圧縮比を20:1と仮定する。
(2) 輸送用タンク20の内部圧力が30MPaである場合、移送用コンプレッサ25が30MPaの高圧ガスから60MPaの高圧ガスを容易に作ることが可能であるので、30MPaのガスを保管タンク27に移送することは簡単である。1000cc、30MPaの高圧ガスは500cc、60MPaの高圧ガスになる。圧縮比は2:1である。
(3) 輸送用タンク20から保管タンク27にガスを移送し続けると、輸送用タンク20の圧力は徐々に減少していく。しかし輸送用タンク20の圧力が3.0MPa以下になっても、移送用コンプレッサ25は3.0MPa以下のガスを保管タンク27に輸送することができる。
(4) 図1における複機能コンプレッサ1は、ピストン3を2回動かすことによって、1.5MPaのガスを60MPaに圧縮することが可能である。また、ピストン3を3回動かすことによって1.0MPaのガスを60MPaに圧縮することが可能である。
(5) 複機能コンプレッサ1は2個のピストンの組み合わせではないので、ガス給油システムに障害物にもならない。また、コンプレッサの入口圧力が大きく変化しても本発明のコンプレッサは有効である。
