<p>PURPOSE:To enhance a heat insulating effect, by providing a heat insulting layer which surrounds each side surface of a pump unit, rod and a fuel pipe so as to be isolated from low temperature liquified gas. CONSTITUTION:A pump unit 4, piston 11, rod 7 and fuel pipe 8 are provided in a fuel tank 1. A heat insulating layer 10, which surrounds each side surface of the pump unit 4, rod 7 and the fuel pipe 8 so as to be isolated from liquid hydrogen 2, is provided. In this way, a length of the rod 7 can be decreased with a less amount of its protruding part to outside the tank 1 by enabling a heat insulating effect of the tank 1 to be enhanced in no relation to the length of the rod 7.</p> |
