Abstract
A valve apparatus comprises a housing, a solenoid operable to receive electrical current flow, and an enclosure, the enclosure housing the solenoid, a magnet coupled to the enclosure, a plunger comprising a stopper and a conductive portion, and a spring coupled to the plunger. When the solenoid receives a first current, the solenoid applies a first magnetic force onto the plunger causing the stopper to disengage from the housing outlet, the conductive portion of the plunger magnetically connects with the magnet, and the stopper remains disengaged from the housing outlet after the first period of time expires. When the conductive portion is magnetically connected to the magnet and the solenoid receives a second current, the solenoid applies a second magnetic force onto the plunger causing the conductive portion of the plunger to disconnect from the magnet so that the stopper engages with the housing outlet.
