ABSTRACT:
An electromagnetically operable valve comprises a valve member slidable in a bore in which there is a seating. The valve member is moved to the closed position by a solenoid having an armature. A tubular coupling member is secured to the armature and is connected to the valve member through an overtravel spring housed within the coupling member. The coupling member has a flange for engagement with a stop surface to limit the movement of the armature after the valve member has contacted the seating. A return spring is also housed within the coupling member.
