An exhaust gas recirculation valve (2) for use with an internal combustion engine for an automotive vehicle, the valve (2) comprising a passageway (6), a closing member (10) that is movable between a closed position and an open position which allows fluid communication through the passageway (6), and an actuator for moving the closing member (10) between its closed and open positions. The actuator includes a driver (26) that in use causes movement of moving parts one of which causes movement of the closing member (10) to the closed position, after which continued operation of the driver moves a second moving part (22). When the driver is operated to open the valve, the second moving part (22) moves back to its previous position and the momentum of this movement assists the movement of the closing member (10) from its closed position to its open position. |
