Abstract:
1. A valve assembly for an engine having a secondary air pump, an exhaust manifold, and an intake manifold, the valve assembly comprising: a member defining a chamber having a first port, a second port, and a third port; a first conduit adapted to be operatively connected to the secondary air pump for fluid communication therewith; a second conduit adapted to be operatively connected to the intake manifold for fluid communication therewith; a third conduit adapted to be operatively connected to the exhaust manifold for fluid communication therewith; a first valve movable between a closed position in which the first valve obstructs the first port to prevent fluid communication between the first conduit and the chamber, and an open position in which the first valve permits fluid communication between the first conduit and chamber through the first port; and a second valve movable between a closed position in which the second valve obstructs the second port to prevent fluid communication between the second conduit and the chamber, and an open position in which the second valve permits fluid communication between the second conduit and the chamber through the second port; said first and second valves being interconnected for unitary movement.
