Abstract
An energy saver valve includes a first spool () and a second spool () slidably received in a passage () of a housing (). The first spool and the second spool are separate components. The energy saver valve also includes a first outlet port (), a second outlet port (), and a resilient member () located in a resilient member chamber () that biases the second spool towards the first spool. Fluid exits the first outlet port at a first pressure when the energy saver valve is in an initial position, and another passage () provides fluid communication between the fluid in the resilient member chamber and the first outlet port. The fluid exits the second outlet port at a second pressure when the energy saver valve is in an actuated position. The first pressure is less than the second pressure.
