ABSTRACT:
The invention provides a variable output pump of the gerotor type in which one rotor meshes in two side by side annulii which can be aligned for maximum output and turned in opposite directions to be non-aligned for minimum output. The movement is effected by a gear train displaced by a rack which is hydraulically operated by pump pressure. Hence high pressure displaces the rack to result in lower output against lower pressure. A variation is described in which a control spool diverts fluid to either side of the piston according to need and this is displaced in one direction by the derived fluid pressure and in the other direction additionally by spring pressure transferred from the piston position by a lever system. This can give desired pump output/speed results at reduced power consumption.
