Two-way selector valve for a vehicle seat inflation device

A two-way selector valve adapted to selectively provide communication between a vehicle seat inflation device having first and second pneumatic chambers disposed therein, a source of pressurized fluid, and the atmosphere, comprising:

• a valve body including an aperture, a valve chamber, and an output chamber;
• a valve spool having an input chamber formed in one end thereof adapted to communicate with the source of pressurized fluid and another end adapted to be inserted in said valve body aperture, said valve spool including a first passageway providing communication between said input chamber and said valve body chamber, a second passageway providing communication between said valve body chamber and a passageway formed in a valve stem connected to said valve spool, and a third passageway providing communication between said valve body chamber and said output chamber;
• first conduit means providing communication between said valve stem passageway and one of the pneumatic chambers;
• second conduit means providing communication between said output chamber and the other of the pneumatic chambers;
• and
• rotatable valve plate means disposed in said valve body chamber for providing communication between said first passageway and a selected one of said second and third passageways for inflating the corresponding pneumatic chamber.

A two-way selector valve adapted to selectively provide communication between a means for selectively supplying pressurized fluid, first and second pneumatic chambers, and the atmosphere comprising:

• a first passageway in communication with the means for selectively supplying pressurized fluid and with a valve chamber;
• a second passageway in communication with the first pneumatic chamber;
• a third passageway in communication with the second pneumatic chamber;
• rotatable valve plate means disposed in said valve chamber for providing communication between said valve chamber and a selected one of said second and third passageways;
• and
• relief valve means mounted for rotation with said valve plate means and movable relative thereto for selectively providing communication between said valve chamber and the atmosphere to deflate the selected chamber.
