Abstract
A valve can include a solenoid coil, a plunger having a core configured to respond to a magnetic field generated by the solenoid coil, and a valve disc. The valve disc can be positioned at a head of the core and configured to cushion impact when the valve is closed. A projection can be positioned and configured to cushion impact when the valve is opened. The valve can be used in an air bed system in fluid connection between an air pump and an inflatable air chamber of a mattress.
