20110209783 | VALVE ASSEMBLIES - An electronically actuatable valve assembly having a primary face seating valve, including a primary valve member, and a secondary valve, including a secondary valve member. The secondary valve opens before the primary valve to equilibrate pressure across the primary valve member and thereby facilitate opening of the primary valve member. The secondary valve is coupled to an armature which moves from a first position to a second position, in use, attracted by an electromagnet. The coupling between the armature and the secondary valve is configured to enable the armature to begin to move from the first position without movement of the secondary valve. The armature has therefore moved from the first position, closer to the electromagnet, when the secondary valve is opened by way of the forces exerted through the coupling between the armature and the secondary valve member, and so a greater force can be exerted to open the secondary valve than would be the case if the secondary valve member was fixedly coupled to the armature. | 09-01-2011 |
