Blowoff valve
![A typical piston-type dump valve, used in auto racing. Unlike a blowoff valve, this one does not vent to the atmosphere. The small hose at the top is a feed from the intake manifold.](/Images/godic/202501/09/Dahlbäck_valve5627.jpg")
![When the throttle plate is open, the air pressure on both sides of the piston in the blow-off valve is equal and the spring keeps the piston down.](/Images/godic/202501/09/Throttle_body_openBOV125627.jpg")
![When the throttle is closed, a vacuum forms in the manifold. This in combination with the pressurized air from the turbocharger moves the piston in the valve up, releasing the pressure into the inlet of the turbo (Recirc.) or the atmosphere (BOV).](/Images/godic/202501/09/Throttle_body_closedBOV75627.jpg")
A blowoff valve (BOV), dump valve or compressor bypass valve (CBV) is a pressure release system present in most turbocharged engines.
