Abstract
A coupling arrangement for fluid coupling a worktool to a machine comprising at least one coupler assembly slideably mounted in a cavity for coupling a machine fluid circuit and a work tool fluid circuit, the coupler assembly partitioning the cavity to form a chamber; a diversion path connecting the machine fluid circuit to the chamber; and a check valve positioned in the diversion path for flow of fluid from the machine fluid circuit to the chamber to generate a force on the coupler assembly for maintaining the fluid coupling.
