Technical Examples

A leak resistant solenoid valve comprises a valve body having an interior chamber, an inlet, an outlet, and at least one valve seat and valve plug located in the interior chamber. The valve plug has a sealing surface and is axially movable between open and closed positions by a solenoid which acts on the valve shaft on which the plug is carried. The valve further comprises a plug actuating mechanism for moving the plug between the open and closed positions with the solenoid energized and a biasing mechanism for biasing the plug back to the open position when the solenoid is de-energized. The plug is preferably loosely received on the shaft so as to provide self-centering. In one embodiment, the valve has a pair of valve plugs and a pair of valve seats, the seats being axially fixed to one another and the distance between the plugs being variable to provide enhanced sealing.
