연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

1. A pressure vessel for storage of a compressed gas, comprising a closed pressure vessel housing having an essentially cylindrical main part and end-caps on both ends, and an integrated control means ( 2 ) for the release of the gas, including a shut-off valve ( 17 ) and a pressure reducer with a high-pressure part ( 8 ) and a low-pressure part ( 13 ) wherein at least one of the end-caps ( 1 ) is an element mounted together with the cylindrical main part and at least the high-pressure part ( 18 ) of the pressure-reducer and the shut-off valve ( 17 ) are mounted to one of the end-caps and are directed into the interior of the vessel housing. 2. Pressure vessel according to claim 1, wherein all components of the high-pressure unit ( 8 ) of the pressure reducer are mounted to the end-cap element ( 1 ) and project into the interior of the vessel housing. 3. Pressure vessel according to claim 2, wherein the lateral expansion of the components projecting into the interior of the vessel altogether does not exceed the lateral extension of the end-cap to which they are connected. 4. Pressure vessel according to claim 3, manufactured as a composite pressure vessel with a liner ( 4 ), wherein at least one end-cap ( 1 ) is a pole-cap which holds the components required for the control of compressed gas and is wrapped, together with the liner, by a fibre reinforcement layer ( 5 ). 5. Pressure vessel according to claim 4, wherein at least one pole-cap ( 1 ) of the pressure vessel is designed in such a way that there are, after adding the fibre reinforcement layer ( 5 ), no components of the control means ( 2 ) which extend beyond the vessel surface besides some elements ( 3 , 3 ′) generating a bias tension for the pressure reducer. 6. Pressure vessel according to claim 3, that is made as a metallic pressure vessel and wherein at least one end-cap ( 1 ) of the pressure vessel encloses the components of the control means ( 2 ) and is welded to the cylindrical main part ( 4 ) of the vessel. 7. Pressure vessel according to claim 6, wherein at least one end-cap ( 1 ) of the metal pressure vessel is shaped in such a way that there are no components of the control means ( 2 ) which project beyond the vessel surface, with the exception of some elements ( 3 , 3 ′) which generate a bias tension for the pressure reducer. 8. Pressure vessel according to claim 7, wherein the control means ( 2 ) includes a pressure reducer, a shut-off valve ( 17 ), a through-flow valve, a fusable cut-out, and either a residual-pressure valve ( 15 ) or a check-valve for filling the pressure vessel, or any combination thereof. 9. Pressure vessel according to claim 5, wherein the at least one pole-cap ( 1 ) of the pressure vessel is split into an inner high-pressure part ( 8 ) which is surrounded by a fibre reinforcement layer ( 11 ), and a low-pressure part ( 13 ) mounted on said first layer and surrounded by a second fibre reinforcement layer ( 14 ). 10. Pressure vessel according to claim 9, wherein the high-pressure part ( 8 ) comprises a residual-pressure valve ( 15 ), a shut-off valve ( 17 ), the components of a pressure reducer up to the valve seat ( 9 ) and a through-flow limiting valve, and wherein further the low-pressure part ( 13 ) comprises a pressure reducer diaphragm ( 12 ) and the gas outlet ( 7 ). 11. Pressure vessel according to claim 10, having two pole-caps opposite each other, wherein a filing-valve and a fusable cut-out are integrated into the pole-cap of the pressure vessel opposite the pole-cap ( 1 ) with the pressure reducer. 12. Pressure vessel according to claim 11, wherein the pressure reducer is controlled either by variations in pressure of a compressed pneumatic auxiliary fluid contained in the housing or by force exerted by a spring. 13. Pressure vessel according to any of claim 12, further including a shut-off valve ( 17 ) which is operated manually, pneumatically or by a solenoid. 14. Pressure vessel according to claim 13, wh erein in the case of operating the shut-off valve ( 17 ) pneumatically or by solenoid, an additional device ( 16 ) for its manual actuation is provided. 15. Pressure vessel according to claim 4, wherein the control means ( 2 ) includes a pressure reducer, a shut-off valve ( 17 ), a through-flow control valve, a fusable cut-out, and either a residual-pressure valve ( 15 ) or a check-valve for filling the pressure vessel, or any combination thereof. 16. Pressure vessel according to claim 6, wherein the pressure reducer is controlled either by variations in pressure of a compressed pneumatic auxiliary fluid contained in the housing or by force exerted by a spring. 17. Pressure vessel according to claim 6, further including a shut-off valve ( 17 ) which is operated manually, pneumatically or by a solenoid. 18. Pressure valve according to claim 17, wherein in the case of operating the shut-off valve ( 17 ) pneumatically or by solenoid, an additional device ( 16 ) for its manual actuation is provided. 19. Pressure vessel according to claim 1, wherein the lateral expansion of the components projecting into the interior of the vessel altogether does not exceed the lateral extension of the end-cap to which they are connected. 20. Pressure vessel according to claim 1, manufactured as a composite pressure vessel with a liner ( 4 ), wherein at least one end-cap ( 1 ) is a pole-cap which holds the components ( 2 ) required for the control of compressed gas ( 2 ) and is wrapped, together with the liner, by a fibre reinforcement layer ( 5 ) and, further, wherein at least one pole-cap ( 1 ) of the pressure vessel is designed in such a way that there are, after adding the fibre reinforcement layer ( 5 ), no components of the control means ( 2 ) which extend beyond the vessel surface besides elements ( 3 , 3 ′) generating a bias tension for the pressure reducer. 21. Pressure vessel according to claim 19, wherein the at least one pole cap ( 1 ) of the pressure vessel is split into an inner high-pressure part ( 8 ) which is surrounded by a first fibre reinforcement layer ( 11 ), and a low pressure part ( 13 ) comprising a pressure reducer diaphragm ( 12 ) and the gas outlet ( 7 ) mounted on said first layer and surrounded by a second fibre reinforcement layer ( 14 ) and, further, wherein the high pressure part ( 8 ) comprises a residual-pressure valve ( 15 ), a shut-off valve ( 17 ), the components of a pressure reducer up to the valve seat ( 9 ) and a through-flow limiting valve. 22. Pressure vessel according to claim 1, that is made as a metallic pressure vessel and wherein at least one end-cap ( 1 ) of the pressure vessel encloses the components of the control means ( 2 ) and is welded to the cylindrical main part ( 4 ) of the vessel and, further, wherein at least one end-cap ( 1 ) of the metal pressure vessel is shaped in such a way that there are not components of the control means ( 2 ) which project beyond the vessel surface, with the exception of elements ( 3 , 3 ′) which generate a bias tension for the pressure reducer.
