ABSTRACT:
A two-way selector valve for a vehicle seat inflation device is disclosed. The selector valve includes a first input passageway connected between a source of pressurized air and a valve body chamber. The selector valve further includes second and third passageways which are connected between the valve body chamber and respective output conduits. Each of the output conduits is connected to a respective pneumatic chamber formed in the vehicle seat. A valve plate having first and second apertures formed therein is disposed within the valve body chamber. The valve plate is rotatable between first and second positions so as to selectively provide communication between the first passageway and a selected one of the second and third passageways. A relief valve is provided adjacent the valve plate for deflating the selected one of the chambers.
