    摘要: A check valve is provided and has a housing having inlet and outlet openings and comprising two essentially planar plate portions. A thin steel plate that acts as a valve is disposed between the plate portions. Under the effective pressure, the valve opens in one direction and blocks flow in the opposite direction. The valve has at least one valve tongue, and the plate portions in the valve are fixedly connected together. One of the plate portions is associated with the discharge zone and in the vicinity of the valve tongue is provided with at least one arched portion for limiting opening of the valve tongue. The other plate portion has bores through which the exhaust gas can enter under overpressure.
