Abstract:A pressure actuated valve comprises a first membrane having a slit extending through the membrane at a nonzero draft angle relative to a perpendicular to a surface of the membrane, material of the membrane biasing the slit closed so that the slit remains closed when a fluid pressure applied to the membrane is below a threshold level and, when the fluid pressure is at least the threshold level, edges of the slit separate from one another to permit fluid flow through the membrane.
