Multi-chamber blowoff valve

A dual-chamber blowoff valve for releasing air pressure from a duct system associated with a vehicle, the dual-chamber blowoff valve comprising:

• a valve housing configured to secure to the duct system at a duct-air interface;
• an engine-air interface configured to allow air in and out of the valve housing;
• an upper chamber disposed within the valve housing;
• a lower chamber fluidly disposed within the valve housing and adjacent to the upper chamber;
• a hollow shaft that allows air to travel from the upper chamber to the lower chamber;
• and
• a dual piston assembly disposed within the valve housing in both the upper chamber and the lower chamber,
• wherein the dual piston assembly is configured to be in a closed position while a pressure differential is above a threshold,
• wherein the dual piston assembly is configured to be in an open position while the pressure differential is below said threshold, such that a portion of the air in the duct system is released.

A multi-chamber blowoff valve for releasing air pressure from a duct system associated with a vehicle, the multi-chamber blowoff valve comprising:

• a valve housing configured to secure to the duct system;
• said valve housing including—
• an engine-air interface configured to allow air in and out of the valve housing;
• at least two chambers disposed within the valve housing,
• wherein said at least two chambers are fluidly connected via a hollow shaft;
• a duct-air interface configured to secure the multi-chamber blowoff valve against the duct system;
• and
• a multiple piston assembly disposed within the valve housing;
• wherein the multiple piston assembly is configured to be in a closed position while a pressure differential is above a threshold,
• wherein the multiple piston assembly is configured to be in an open position while the pressure differential is below said threshold, such that a portion of the air in the duct system is released via the duct-air interface.
