Abstract: A hydraulic fluid coupling for attaching two hydraulic hoses that comprises an inline swivel joint to prevent twisting of the hoses. The coupling comprises a first and second coupling portion, with the second coupling portion rotatable relative to the first coupling portion. There are two bearings and a ring shaped piston that slides toward the second bearing in response to fluid pressure inside the coupling. Engagement of the piston with the second bearing urges the second coupling portion towards the first coupling portion, against the action of fluid pressure between the first and second couplings. This reduces the load on the first bearing and transfers some of that load to the second bearing, thereby making it easier to rotate the second coupling portion.
