TOOL COUPLER ASSEMBLY

摘要

A tool coupler assembly for a machine is disclosed. The tool coupler assembly may have a coupler frame, a first latch, a second latch, and a hydraulic actuator connected to move the second latch relative to the first latch and the coupler frame. The hydraulic actuator may have a first chamber, a second chamber, and a pressure valve with a check element movable to allow a flow of fluid into the first chamber based on a pressure of fluid in the first chamber, and a pressure regulating element movable to allow a flow of fluid out of the first chamber based on a pressure of fluid in the second chamber. The tool coupler assembly may additionally have a first pilot passage configured to communicate fluid from the second chamber with the pressure-regulating element, and a second pilot passage configured to communicate fluid from the first chamber with the pressure-regulating element.
