Abstract
A pressure container has an inner shell with a pair of fittings and a reinforcement layer formed around the inner shell, and is configured so that a reinforcement member is attachable to the pair of fittings in a process of forming the reinforcement layer and a functional component which performs a predetermined function is also attachable to the fittings. This can allow the reinforcement member to prevent expanding deformation of the pressure container in production of the pressure container, and can ensure effective use of openings after removal of the reinforcement member.
Claims13
A pressure container having an inner shell and a reinforcement layer formed around the inner shell, comprising:
- a deformation restricting part to which a reinforcement member is attachable in a process of forming the reinforcement layer and which restricts expanding deformation of the inner shell by interaction with the reinforcement member, the reinforcement member attached in the forming process being removed after the pressure container is completed,
- wherein the reinforcement member and the deformation restricting part restrict expanding deformation in a lengthwise direction of the pressure container while permitting contracting deformation, and
- wherein the reinforcement member is slidable with respect to the deformation restricting part at the time of the process of winding fibers to form the reinforcement layer.
A method of producing a pressure container having an inner shell with a fitting and a reinforcement layer formed around the inner shell, comprising:
- forming the reinforcement layer after providing a reinforcement member, which is slidable with respect to the inner shell at the time of the process of winding fibers to form the reinforcement layer and restricts expanding deformation in a lengthwise direction of the pressure container while permitting contracting deformation at the fitting at the time of forming the reinforcement layer around the inner shell after forming the inner shell;
- removing the reinforcement member from the fitting after forming the reinforcement layer;
- and
- attaching a functional component which performs a predetermined function to the fitting with the reinforcement member removed therefrom.
