Abstract: A gasket includes a first compressible portion, a second incompressible portion integrally formed with the first compressible portion, and a flexible coating disposed on one or more of the first compressible portion and the second incompressible portion. The first compressible portion is substantially planar and includes a plurality of layers, and the second incompressible portion is substantially planar and includes a first of the plurality of layers.

Abstract: A gerotor pump assembly, and a system and method for operating a gerotor pump assembly, result in a lubrication strategy for operating in a loss-of-prime mode. An inner drive gear may be rotated in a first direction and in a second opposite direction about an axis of rotation. The inner drive gear has a number of projections extending outwardly therefrom. An outer driven gear surrounds the inner drive gear and defines a number of recessions along an inner surface configured to engage with the projections of the inner drive gear. The outer driven gear and the inner drive gear further define at least one dynamically-changing fluid cavity therebetween. The inner drive gear and the outer driven gear define an oil transfer volume clearance between a projection and a recession in a fully engaged position. Oil is maintained within the oil transfer volume clearance as the inner drive gear is rotated.
