Abstract
A coupling joint for releasably coupling two telescoping tubular members in sealing relationship to one another, one of the tubular members being continuously urged inwardly relative to the other tubular member whereby a seal between said members may be maintained at all times. The coupling joint, which may be utilized in a valve or the like with the valve body representing one of the tubular members and a bushing representing the other of the tubular members inserted into the open end of the valve body, includes the use of a resilient ring such as an O-ring for retaining the two tubular members together, the ring being positioned in opposed grooves in the telescoped portion of the tubular members. One of the grooves on one of the tubular members is a retaining ring groove for retaining the resilient ring during assembly of the two tubular members, and the other of the grooves on the other of the tubular members is a groove having a camming surface thereon so oriented that when the grooves are opposed to one another with the resilient ring therebetween, the compressive forces in the resilient ring seeking to expand the same exert resultant forces on the tubular members to cause said tubular members to be urged toward one another.
