Abstract
A pressure vessel containing compressed fluid includes: a plurality of tank cells, each of the tank cells extending along a first direction and disposed along a second direction perpendicular to the first direction, each of the tank cells containing compressed fluid; and a sheet-like fixation member wound around a periphery of the tank cells and configured to integrally bind the tank cells. A gap extending along the first direction is provided between two of the tank cells adjacent to each other and the fixation member. A reinforcement member is provided on an inner surface of the fixation member, the reinforcement member extending in the gap in the first direction and protruding toward the two adjacent tank cells. A surface of the reinforcement member is positioned away from each of surfaces of the two adjacent tank cells.
Claims4
A pressure vessel configured to contain compressed fluid, the pressure vessel comprising:
- a plurality of tank cells, each of the tank cells extending along a first direction and disposed along a second direction perpendicular to the first direction, each of the tank cells being configured to contain compressed fluid;
- and
- a fixation member wound around a periphery of the tank cells and configured to integrally bind the tank cells, the fixation member being a sheet, wherein:
- a gap extending along the first direction is provided between two of the tank cells adjacent to each other and the fixation member;
- a reinforcement member is provided on an inner surface of the fixation member, the reinforcement member extending in the gap in the first direction and protruding toward the two adjacent tank cells;
- a surface of the reinforcement member is positioned away from each of surfaces of the two adjacent tank cells;
- each of the tank cells includes
- a pair of plate members provided at both end portions in the first direction, and
- a band member spanned between the plate members;
- and
- at least part of the band member extends inside the reinforcement member.
