Abstract:
A pressure relief valve includes a base including a fluid inlet and outlet, a nozzle, and a disc. The nozzle includes a substantially annular seat, a substantially cylindrical seat inlet, and a substantially cylindrical bore in fluid communication with the seat inlet. A ratio between a bore diameter and a seat diameter is a constraint ratio. The disc contacts the seat to seal the fluid inlet to substantially prevent fluid communication between the fluid inlet and outlet when the valve is closed. The disc and the disc holder are adapted to be urged by fluidic pressure such that contact between the disc and the seat is removed at the fluidic pressure to allow fluid communication between the fluid inlet and the cavity. Dimensions of the disc, the disc holder, and the nozzle may be functions of the seat diameter and limited by the constraint ratio.
