ABSTRACT:
A seal assembly comprised of a pair of concentric rings radially spaced with a tortuous or convoluted channel therebetween in which is carried a rubber-like compressible seal element that extends beyond the radial surfaces of the rings. The inner ring has passages for flow between registering passages of assembled components, e.g., radial piston pumps. Such passages are inside the perimeter of the seal element and within convolutions. The outer ring has apertures for passage of screws for assembling the components together, thereby compressing the sealing element during assembly to effect a tight seal. The compressed material is displaced into adjoining concavities molded into the sealing element within the thickness of the concentric carrier rings.
