Abstract:
1. An elastic arm fixed at one end and attached to a flexible cover at an opposed end, whereby the said cover is about congruent with and contiguously overlaps a port which discharges fluid, such that a device comprised of the said elastic arm, said cover, and said port are substantially similar to a check valve, whereby the edge of the said elastic arm substantially surrounds the outer edge of the said cover, and is adjacent and close to the said outer edge but does not overlap the said cover, whereby the surface of the said elastic arm is about planar with the surface of the said cover, whereby the said opposed end attachment is offset from the center of the said cover, thereby when the said cover is urged in a direction about perpendicular to the said cover surface, the said cover urge superimposes with an elastic arm urge, whereby the said port is comprised of a plurality of passages predetermined in flow area and location, such that the velocities of the said fluid traversing from the said passages to the said cover are predetermined, thereby the direction of the said fluid traversing efferent from the said cover center to the said cover edge are about parallel with the said elastic arm surface, thereby fluid drag urged upon the said elastic arm is about zero; wherein a symmetrically opposed and substantially similar elastic arm is disposed in the plane of the said cover surface, whereby the lengths of the said elastic arms are about the width of the said cover, and do not overlap each other or the said cover, whereby the said symmetrically opposed elastic arm is also fixed at one end and attached to the said cover at the opposed end, thereby an acclivity of the said cover surface about an intersecting axis of a plane of said symmetry and the plane of the said cover surface is about zero when urged in the said perpendicular direction relative to the said acclivity when not urged.
