Abstract:
A method for manufacturing a membrane valve for installation between mating surfaces of a cylinder block containing a cylinder and a valve head of a compressor for allowing uni-directional flow of fluids between said cylinder and said valve head, comprising the steps of:a. forming a planar body of a maximum thickness ""T"" with an opening defined by a continuous internal edge, said opening having first and second, axially spaced opposite ends such that a longitudinal axis of said opening extends between said first and second ends,b. forming a planar membrane of maximum thickness ""T"" with a peripheral edge corresponding to said continuous internal edge of said body,c. positioning said planar membrane within said opening of said planar body in coplanar relationship with said body so that said peripheral edge of said planar membrane and said continuous internal edge of said body define a gap extending peripherally therebetween, andd. flowing a joining medium across a portion of said gap near said first end to attach a portion of said peripheral edge of said membrane to a corresponding portion of said internal edge of said planar body by said joining medium having a thickness which is not greater than maximum thickness ""T,"" whereby said membrane can pivotally move about a transverse axis, which is coplanar with said body, near said first end when installed between said cylinder block and said valve head.
