ROTATIONAL FLUID JOINT FOR AGRICULTURAL MACHINE

摘要

A rotational joint is provided for an agricultural machine having hinged frame sections, each frame section carrying one or more plumbing lines for moving a carrier fluid. The rotational joint includes first and second joint parts. Each joint part has a coupler defining a flow passage leading to an interface opening. The joints parts are coupled to allow for relative rotation about a rotation axis passing through the interface openings. In at least one angular orientation of the joint parts, the flow passages of the couplers are in fluid communication.

1. In an agricultural machine having a first frame section and a second frame section hinged to the first frame section, the first frame section and the second frame section each carrying one or more plumbing lines for moving a carrier fluid, a rotational joint comprising:
a first joint part having a first coupler defining a first flow passage leading to a first interface opening; and a second joint part having a second coupler defining a second flow passage leading to a second interface opening; wherein the first joint part is coupled to the second joint part to allow for relative rotation about a rotation axis passing through the first and second interface openings; and wherein, in at least one angular orientation of the first and second joint parts, the first flow passage of the first coupler is in fluid communication with the second flow passage of the second coupler.
