Abstract
A fluid pump includes a housing defining a cavity. An end plate is disposed within the cavity and divides the cavity into a gear section and an end section. A gear set is disposed within the gear section and comprises at least one gear rotatable about an axis. The end plate is movable longitudinally along the axis for compressing the gear set. A channel is in fluidic communication with the end section for supplying a fluid to the end section to force the plate toward the gear set.
