Abstract

A high-pressure tank producing apparatus capable of reducing time for increasing temperature of a tank body. The apparatus that heats the tank body with fibers impregnated with a thermosetting resin wound around its surface includes a heating chamber for housing the tank body and a retaining mechanism for retaining the tank body within the heating chamber, in which the heating chamber has an injection port for injecting heated gas onto the surface of the tank body and an exhaust port for discharging the gas to the outside of the heating chamber, the exhaust port being disposed in a position where the injection port is projected in a gas injecting direction, and the retaining mechanism retains the tank body in a region where the injection and exhaust ports overlap with each other as viewed from the gas injecting direction and in a position between the injection and exhaust ports.

First claim

What is claimed is:

1 . A high-pressure tank producing apparatus that heats a tank body with fibers impregnated with a thermosetting resin wound around its surface so as to cure the thermosetting resin, the high-pressure tank producing apparatus comprising:
a heating chamber adapted to house the tank body; and a retaining member adapted to retain the tank body within the heating chamber, wherein: the heating chamber has an injection port for injecting heated gas onto a surface of the tank body and an exhaust port for discharging the gas to an outside of the heating chamber, the exhaust port being disposed in a position where the injection port is projected in a gas injecting direction, and the retaining member retains the tank body in a region where the injection port and the exhaust port overlap with each other as viewed from the gas injecting direction and in a position between the injection port and the exhaust port.

2 . The high-pressure tank producing apparatus according to claim 1 , wherein
the tank body comprises a cylindrical cylinder portion and dome portions provided in opposite end portions in an axial direction of the cylinder portion, and the injection port is provided so as to inject the gas onto a surface of the cylinder portion.

3 . The high-pressure tank producing apparatus according to claim 2 , wherein an opening width of the injection port in a radial direction of the cylinder portion is smaller than an outer diameter of the cylinder portion.

4 . The high-pressure tank producing apparatus according to claim 2 , wherein an opening width of the exhaust port in a radial direction of the cylinder portion is smaller than an outer diameter of the cylinder portion.

5 . The high-pressure tank producing apparatus according to claim 2 , wherein a distance between the injection port and the cylinder portion and a distance between the exhaust port and the cylinder portion are each shorter than an outer diameter of the cylinder portion.
