SYSTEMS AND METHODS FOR SELECTIVELY ENGAGED REGENERATION OF A HYDRAULIC SYSTEM

摘要

A hydraulic system and method for using the same are provided. The hydraulic system includes a pump, a first actuator having a first head chamber and a first rod chamber, and a second actuator having a second head chamber and a second rod chamber. The hydraulic system further includes a first control valve and a second control valve. The second control valve to selectively provide regeneration fluid flow from the first rod chamber to the first head chamber in response to a first function command is less than a first function command limit, a second function command is greater than a second function command limit, and a second function load is greater than a second function load limit.

主权项

1. A control valve assembly for a hydraulic system, the hydraulic system including a first function operated by a first actuator, a second function operated by a second actuator, and a pump to furnish fluid from a reservoir to a supply conduit, the first actuator including a first head chamber and a first rod chamber and the second actuator including a second head chamber and a second rod chamber, the control valve assembly comprising:
a first control valve to selectively provide fluid communication between the first actuator and both the supply conduit and the reservoir in response to a first function command; a second control valve to selectively provide fluid communication between the first actuator and both the supply conduit and the reservoir in response to the first function command; the second control valve to selectively provide regeneration fluid flow from the first rod chamber to the first head chamber when a first function command is less than a first function command limit, a second function command is greater than a second function command limit, and a second function load is greater than a second function load limit.
