Abstract
The present invention relates to a bleed member provided in a bleed valve assembly having a wall member defining a fluid chamber for retaining a fluid therein. The bleed member has an aperture defined in the wall member and a flexible sealing member located inside the fluid chamber for selectively covering and sealing the aperture. According to the present invention, in a preloading state, the flexible sealing member covers and seals the aperture and, in a venting state, the sealing member is forced to be unseated from the aperture to vent fluid from the valve member. The wall member is preferably flexible and the sealing member may be formed of a material which is flexible and conforms to the shape and configuration of the wall member to seal the aperture.
