Abstract

An apparatus and method for a pressure relief door for an engine compartment having a wall and an opening (104) in the wall includes a door panel (102) arranged for blocking the opening (104), a plurality of hinges (150) coupling the door panel (102) to the wall of the engine compartment, a spring assembly (200) coupled between each hinge (150) and the inner surface of the wall, wherein the spring assembly (200) includes a canister having an open end and a spring element housed within the canister (220), and a spring retainer mounted to the engine compartment wall and having a portion extending toward the open end of the canister (220) for applying a compressive force on the spring element (222). The spring element (222) has one end portion communicating with the open end of the canister (220), and the spring retainer portion is positioned against the one end portion of the spring element. The canister (220) is pivotally mounted to the hinge element (150) between the end portions thereof, and the spring assembly (200) support bracket associated with each hinge includes a free end portion located adjacent the canister (220), the end portion of the spring assembly (200) support bracket being operatively coupled with the free end portion of the spring assembly (200) support bracket to cause a pre-load compressive force to be exerted on the spring element (222) in advance of any movement of the door panel (102) into or out of the engine compartment wall opening. As a result of the spring compression and the distance between the axis of compression and pivot axis of the hinge, a near constant opening and closing force controls the motion of the door panel (102) throughout its entire range of motion.
