Abstract
An equalization shutoff valve includes a housing having an outward extending flange around an open end of the housing, retaining clips attached to the flange configured to engage a battery pack compartment, and piston guides disposed inside the housing; a piston having guide notches engaging the piston guides, and a first flow port; a spring disposed between the housing and the piston to urge the piston in a direction away from a closed end of the housing; and a locking tab cover attached to the housing with the piston inside the housing, and having a second flow port and locking tabs with clip ports. The housing is attached to the battery pack compartment through the retaining clips so that air flows from inside the battery pack compartment, and when pressure inside the housing increases, increased pressure pushes the spring and the piston to allow air to exit from the housing.
