Abstract
A bypass valve assembly for a fluid device, such as a heat exchanger, has a plate-like main body defining an inlet opening and an outlet opening communicating with the inlet and outlet of the fluid device. The main body has a bypass passage extending between the inlet and outlet openings therein. A tubular flapper valve assembly is releasably located in the outlet opening of the main body. The tubular flapper valve assembly includes a semi-cylindrical spring flapper which opens to allow bypass flow when the pressure in the bypass passage exceeds a predetermined limit. The tubular flapper valve assembly is orientated to allow flow therethrough from the fluid device outlet.
