摘要： A negative pressure valve assembly is provided. The valve assembly comprises a valve port assembly comprising a port and a flange substantially surrounding the port, a valve comprising a plate adapted to substantially cover the port, the plate comprising a minor edge, a major edge having a major edge length, and a plate biasing assembly stop located at a first position along the major edge, the first position more than 50% of the major edge length as measured from the minor edge. The valve assembly further comprises a hinge coupled to the plate, the hinge adapted to couple the plate to the flange, and first plate biasing assembly adapted to couple to the valve port assembly and to bias the plate towards the valve port assembly, the first plate biasing assembly comprising a resilient member adapted to contact the stop plate.
