Abstract
Micro-hydraulic supply and storage units capable of recovering waste energy and storing energy for later use, such as for operating hydraulic valve actuation and high pressure fuel injection systems. The system includes a sump, a pump motor, an accumulator and a supply rail. Valving is provided to couple the outlet of the pump motor to the accumulator to fill the accumulator with what otherwise would be waste energy, such as when a vehicle is using its engine for braking, directing the output of the pump motor to a supply rail to maintain the pressure in the supply rail, and directing the output of the pump to a sump. The valving also allows directing an outlet of the accumulator to an inlet of the pump motor for recover of the energy in the accumulator. Other aspects of the invention are disclosed.
