INDEPENDENT CORNER LIFT SYSTEM FOR VEHICLES

A height adjustment system for a vehicle includes: a reservoir configured to hold hydraulic fluid; at least one lift actuator operably disposed between a wheel and a chassis element of the vehicle for adjusting the height of the vehicle; a supply pump having an inlet port in fluid communication with the reservoir and configured to transfer the hydraulic fluid to the at least one lift actuator via a manifold; a supply check valve configured to allow fluid flow from an outlet of the supply pump to the manifold while blocking fluid flow in an opposite direction; and at least one of: a supply pump isolation valve configured to selectively bypass hydraulic fluid around the supply check valve, or a secondary actuator isolation valve configured to selectively control fluid flow between the at least one lift actuator and the inlet port of the supply pump.
