Abstract

A vent structure may include a vent housing comprising an inlet, an outlet, at least one exhaust gas orifice, and a membrane having a first end and a second end spaced apart, the membrane having a moveable portion between the first end and the second end. The moveable portion may be spaced radially from a membrane-facing surface inside of the vent housing to form an exhaust gas flow passage therebetween to allow exhaust gas to flow from the pressurised volume through the exhaust gas flow passage to atmosphere via the exhaust gas orifice. The moveable portion may be elastically deformable and configured to move radially relative to the membrane-facing surface in response to pressure differences between an interior side of the membrane and an exterior side of the membrane to change a cross-sectional area of the exhaust gas flow passage and regulate the vent flow of gas.
