Abstract
Pressure balancing apparatuses and methods disclosed here include embodiments with a waterproof enclosure having walls surrounding an interior chamber, a mounting interface mounted to the enclosure with a port to an outside, and a balancing module, connected to the mounting interface, the balancing module including, a balancing module housing, a valve actuator member inside the balancing module housing, with a receptacle for a pressure source. In certain embodiments the valve actuator member is configured to move in response to changes in differential pressure between a pressure in the enclosure chamber and pressure from the outside, and a module valve, inside the balancing module housing, connected to the valve actuator member, and fluidically separating the enclosure chamber from the port to the outside, wherein the module valve is configured to open and close in response to the movement of the valve actuator member.
