Abstract: A vehicle having a device that uses an input provided from a first hydraulic system to charge one or more other hydraulic systems. The first hydraulic system can be a vehicle brake system or a hydraulic system having an electrically operated pump. The hydraulic systems to be charged could include an engine lubrication system and/or a transmission hydraulic control system.

Abstract: A pressure-relief valve for a lubrication system includes a housing defining a first chamber and a second chamber separated by a passageway, a biasing element disposed within the first chamber, a piston having a first piston portion disposed within the first chamber and a second piston portion disposed within the second chamber, and a first inlet in fluid communication with the first chamber. The first inlet allows a fluid to enter the first chamber and act upon the first piston portion to compress the biasing element at a first pressure level. The pressure-relief valve also includes a second inlet in fluid communication with a solenoid and the second chamber. The solenoid has a first position allowing the fluid to enter the second chamber to act upon the second piston portion, combining with the fluid acting upon the first piston portion to compress the biasing element at a second, lower pressure level.
