摘要: An electronically controlled valve includes a travelling member comprising a sealing member (12) and operable between a closed position in which the sealing member (12) forms a seal with a valve seat (4), and an open position. The valve further comprises a decelerating mechanism, such as a damping mechanism, operable to slow the movement of the armature (18) during closure of the valve. The sealing member (12) and armature (18) are decoupled and thereby moveable relative to each other such that the armature (18) can continue to move and decelerate due to the action of the damping mechanism after the sealing member (12) has impacted the valve seat (4). The peak deceleration force on the armature is thereby reduced, increasing the lifetime of the valve or the maximum rate at which it can be closed without damage.
