Air Pressure Vessel For A Transportation Vehicle

An air pressure vessel for use in a transportation vehicle comprising:

• a first end cap comprising:
• a first end and a distal end spaced in an axial direction;
• a wall formed from polymeric material extending between the first end and the distal end of the first end cap;
• reinforcing ribs integrally formed in the wall at the first end of the first end cap;
• and
• a first mount positioned at the first end of the first end cap and connected to the reinforcing ribs of the first end cap, the first mount configured to mount the air pressure vessel to a transportation vehicle;
• a second end cap spaced in the axial direction from the first end cap, the second end cap comprising:
• a first end and a distal end spaced in the axial direction, the distal end of the second end cap is connected to the distal end of the first end cap at a central seam;
• a wall formed from polymeric material extending between the first end and the distal end of the second end cap;
• reinforcing ribs integrally formed in the wall at the first end of the second end cap;
• and
• a second mount positioned at the first end and connected to the reinforcing ribs of the second end cap, the second mount configured to mount the air pressure vessel to the transportation vehicle, wherein the wall of the first end cap and the wall of the second end cap each includes an inner surface and an outer surface, the inner surface of the first end cap and the inner surface of second end cap defining an inner volume of the pressure vessel;
• and
• an external sheath substantially surrounding the outer surface of the first end cap and the second end cap.
