Abstract A blowoff valve is composed of cylindrical valve body and cam-type valve with sectorial arc surface and linked to the rotary oxle via crank. A layer (0.5-0.6mm) of teflon is coated on the sealing arc surface. An eccentricity not less than 5mm exists between the arc center of valve core and rotary axle for self locking in close state. Said valve core and valve body have cutting edges to shear off the obstacle when valve is closing.
