Patent ID: 7938451

Claim:
A swivelling coupling assembly for providing a swivellable connection in a load-sensing hydraulic circuit between at least a pair of lines containing a hydraulic fluid, the swivelling coupling assembly comprising: a housing having external spherical surfaces; a retention member for retaining the housing while cooperating with the external spherical surfaces to allow the housing to spherically swivel therein; said housing having bores therethrough, each bore having first and second apertures, the first aperture allowing the fluid to flow therethrough from one of the lines; and at least two pairs of male components, each pair being mountable within one of the bores of the housing, each male component being independently swivellable within said bore and configured to prevent external leakage of the fluid, each male component having a port connectable to a line at a corresponding aperture of said bore and further having a canalization allowing the hydraulic fluid to flow between a pair of lines connected to the port.
