ABSTRACT:
A door on a vehicle is provided with a packing assembly including at least one inflatable member which can be pressurized by a medium such as compressed air from a pressure source so that a completely satisfactory seal is attained. The system includes a control apparatus which responds to a speed sensor to act on a pressure sensor which controls a multi-way valve to supply pressure medium above a determined speed but below a determined pressure. When the pressurization exceeds a predetermined pressure level, the supply of medium under pressure is terminated and the pressurized member is maintained pressurized by a check valve. When used in vehicles, the structure provides a good seal around an openable closure but permits easy opening after depressurization.
