A motor-driven vehicle includes a vehicle body. A wheel has a fixed axle secured to the vehicle body. A driving arrangement which includes a driving unit and a battery is built in the wheel. A manipulating unit is mounted on the vehicle body, which produces an electrical signal to be supplied to the driving arrangement. The fixed axle has a hollow in it, and a signal line interconnecting the manipulating unit and the driving arrangement is disposed in the hollow in the axle.

Motor-driven vehicle

A liquefied gas pump includes a piston and a cylinder which form a pump chamber into which a liquefied gas entrance path and a liquefied gas discharge path open. Relative upward and downward motion between the piston and cylinder provides a repetition of alternating suction and discharge stroke. Liquefied gas is sucked into the pump chamber through the entrance path during the suction strokes, and is discharged out of the pump chamber through the discharge path during the discharge strokes. A separate bubble discharge path opens into said pump chamber at a location in the bottom of an upward recess formed in the top portion of the pump chamber. The bottom of the recess is located above the location where the opening of the liquefied gas discharge path is formed.

A system for vaporizing liquefied gas fuel supplied from a fuel tank and supplying it to an internal combustion engine includes a release path for releasing spontaneously evaporated fuel gas in said tank out of the tank. A catalytic burner is disposed in the release path for decomposing the fuel gas into hot steam and carbon dioxide. A release control valve disposed between the catalytic burner and the fuel tank selectively causes the burner and the fuel tank to communicate and to be decoupled from each other.
