Abstract
An integrated hydraulic system for an automotive vehicle includes a hydraulic pump (16) coupled with and driven by an internal combustion engine (12) and internal and external hydraulic circuits for operating hydraulically powered engine accessories and hydraulically powered chassis components. An electronic controller (18)) sensing a variety of operating parameters controls the output of the hydraulic pump (16) so as to assure that adequate hydraulic fluid is provided to the various components and accessories.
Claims10
An integrated hydraulic system for an automotive vehicle having a chassis and engine power, comprising:
- an internal combustion engine;
- a hydraulic pump coupled with and driven by said engine with said pump having low and high pressure sections;
- an internal hydraulic circuit contained within said engine, with said internal circuit being operatively connected with both the low and high pressure sections of said pump, as well as with a plurality of hydraulically powered engine accessories, so as to selectively furnish hydraulic fluid under low and high pressure to said accessories;
- an external hydraulic circuit extending from both the low and high pressure sections of said hydraulic pump to a plurality of hydraulically powered chassis components, so as to selectively furnish hydraulic fluid under low and high pressure to said chassis components;
- and
- an electronic controller for operating said hydraulic pump so as to control the effective displacement of the pump in response to the pressure and volume requirements of the accessories and components connected to said internal and external hydraulic circuits.
