Abstract:
The apparatus of the present invention provides a compact dual-pump assembly for an automotive transmission. The dual-pump assembly preferably includes a housing having a valve assembly mounted thereto. The valve assembly includes a shuttle valve disposed in fluid communication with a pressure regulating valve. An on-axis pump is mounted to the housing in fluid communication with the shuttle valve and the pressure regulating valve. An off-axis pump in fluid communication with the shuttle valve is mounted to the housing in close proximity to the on-axis pump such that the dual-pump assembly is compact.
