ABSTRACT:
A hydraulic pump assembly for use in combination with an accumulator comprises a pump housing provided with an inlet port for connection to a fluid reservoir and an outlet port for connection to the accumulator, a single cam shaft rotatably mounted within the housing to be driven by an electric motor, a first plunger pump assembly of large displacement capacity including a first plunger axially slidably disposed within the housing perpendicularly to the cam shaft to be reciprocated by engagement with the cam shaft, and a second plunger pump assembly of small displacement capacity including a second plunger axially slidably disposed within the housing perpendicularly to the cam shaft to be reciprocated by engagement with the cam shaft and opposed to the first plunger. An exhaust check valve of the first plunger pump assembly is interconnected to a suction check valve of the second plunger pump assembly.
