Abstract
A rotary union includes a housing forming a bore and a piston bore having an open end and disposed at a radially offset distance with respect to the bore. The piston bore is fluidly isolated from the bore. A seal carrier is slidably disposed within the bore, and includes an actuation arm extending radially outwardly relative to the bore such that it overlaps the piston bore. A piston slidably disposed in the piston bore is extendible to releasably abut the actuation arm and urge the seal carrier to displace relative to the bore when the piston displaces relative to the piston bore.
