Abstract
A motor vehicle vacuum driven hydraulic balance system includes a housing. A shaft rotatably supported in the housing has a longitudinal bore to deliver oil flow to a plurality of ports created in the shaft. A vacuum flow passage communicates with both the longitudinal bore and an oil sump. A first delivery passage is created in a portion of the housing, the first delivery passage in direct communication with the longitudinal bore. An electrical oil pump pumps oil from the oil sump to the longitudinal bore through the first delivery passage. Axial rotation of the shaft creates a partial vacuum in the longitudinal bore acting to vacuum drag oil from the oil sump through the vacuum flow passage to the longitudinal bore in addition to a volume of the oil delivered to the longitudinal bore by the electrical oil pump.
