ABSTRACT:
A pressurized gas driven vehicle, such as a toy automobile, comprises a body which defines a pressure chamber for confining pressurized gas. A nozzle is mounted on the body and has a jet outlet passage which communicates with the pressure chamber. An electrically conductive seal, which disintegrates when sufficiently large electric current is passed through it, is attached to the nozzle to cover the outlet passage and close the pressure chamber. Accordingly, pressurized gas is released from the pressure chamber to launch the vehicle by electrically disintegrating the seal. The nozzle also has an inlet conduit, communicating with the pressure chamber, that is sealed by a resilient valve flap to prevent back-flow of pressurized gas. The inlet conduit and valve flap are arranged to permit charging of the vehicle by placing it in a pressurized atmosphere.
