Abstract
The pump apparatus for delivering liquefied gas includes a suction container and a pump. The suction container has a vacuum insulation container and a vacuum insulation lid. The pump is disposed in a pump chamber formed in the vacuum insulation container. A gas-layer space for forming a gas insulation layer made of the boil-off gas is formed between an inner surface of the vacuum insulation container and an outer surface of a hermetic structure of the vacuum insulation lid. The gas-layer space s in communication with the pump chamber.
