Abstract
A vent connects a chamber to the external atmosphere surrounding a device to equalize pressure within the chamber. The vent has a size and shape to allow pressure equalization to occur outside a normal operating cycle of the chamber and controls the pressure to prevent undesirable deflection of a membrane within the chamber and ensure proper operation of the device.
