A solenoid valve for an air gun substantially increases the rate at which maximum air flow is achieved, and includes a coil actuated plunger (5), which is preferably solid and formed of a magnetically permeable material and closes an annular 360 degree port opening in a chamber (16) between the valve inlet (14) and valve outlet (15) when in the unactuated state. This plunger position is maintained by a biasing spring (2) which forces the forward annular sharp plunger edge against a face seal (12) in the nose of the valve, thereby sealing the valve input port from its output port. Upon actuation of the solenoid valve coil, the plunger is moved against the bias of the spring very rapidly, thereby speedily uncovering the channel between inlet and outlet and permitting rapid 360 degree communication between the inlet and outlet to permit maximum air flow therebetween and out of the outlet port. Air flow is past the edge of the plunger and along an unimpeded 360 degree path rather than through a hollow stem. |
