Abstract
A vehicle solenoid valve includes a coil case with a plunger housing disposed therein. The plunger housing establishes a first fluid communication path and a second fluid communication path. Reciprocably disposed within the plunger housing is a plunger. The plunger is movable between a de-energized configuration wherein fluid communication through the first fluid communication path is permitted and fluid communication through the second fluid communication path is blocked, an energized configuration, wherein fluid communication through the first fluid communication path is blocked and fluid communication through the second fluid communication path is permitted, and a pressure relief configuration, wherein, while the valve is energized, fluid pressure on the plunger surpasses a predetermined pressure level to overcome an opposing magnetic force on the plunger and permit fluid communication through the first fluid communication path.
