Pressure relief valve assembly
A pressure relief valve assembly includes a carrier, a valve, and a baffle. The carrier includes a first end and a second end. The first end defines a first opening. The second end defines a second opening. The carrier defines a flow passage extending from the first opening to the second opening. The valve is supported by the carrier and is operable in an open position and a closed position. In the open position, the valve permits a flow of fluid through the first opening. In the closed position, the valve inhibits the flow of fluid through the first opening. The baffle is disposed in the flow passage. The baffle and the carrier collectively define a flowpath extending through the flow passage.
1. A pressure relief valve assembly comprising:
a carrier extending from a proximal end to a distal end along a longitudinal axis, the proximal end defining a plurality of first openings and the distal end defining a plurality of second openings, wherein the carrier comprises a plurality of flow passages, each of the plurality of flow passages extending from one of the plurality of first openings to one of the plurality of second openings and the plurality of the first openings concentrically disposed about the longitudinal axis;
a valve supported by the carrier at the proximal end of the carrier and concentrically received therein and moveable between an open position and a closed position, wherein the valve is configured to permit a flow of fluid through the plurality of the first openings in the open position, and the valve is configured to inhibit the flow of fluid through the plurality of the first openings in the closed position; and
a baffle concentrically disposed in the carrier, the baffle and the carrier collectively defining a flowpath in the carrier,
wherein the flowpath defines a helical shape,
