摘要： A variable delivery fixed displacement pump is provided which has a rotating drive plate with a fixed angle. The drive plate has a fill passage extending between its radial outer surface and its drive surface, which allows fluid to be supplied to a fluid journal bearing. The drive plate also has a series of bearing supply passages which fluidly connect the drive surface of the drive plate with a base surface, allowing fluid to be supplied to a fluid thrust bearing. A method of pumping fluid is also provided which is comprised of the steps of reciprocating a plurality of pistons at least in part by rotating the drive plate, and by fluidly connecting a pumping chamber of the pistons to an annular groove that is part of the drive plate fill passage.
