Abstract
This invention relates to a unitary centrifugal fluid fuel pump diffuser ring assembly for use between a low pressure source of fluid on a fluid input side of the diffuser ring and a high pressure fluid exit side of the diffuser ring. In the preferred embodiment of the invention a diffuser ring is disposed in mating engagement between a pair of support structures. The diffuser ring is provided with separate fluid sealing units disposed between a first and a second side of the diffuser ring. The fluid sealing units cooperate with the support structures to provide on the first and the second sides of the diffuser ring regions which are free from the effects of the aforenoted low and high pressures. This arrangement results in a reduction in the force required to hold the diffuser ring and the support structures in a unitary assembly free of fluid leakage.
