摘要 |
A removable retainer has a plurality of lugs projecting outwardly from its surface for cooperating with a like number of lugs projecting inwardly from the inner surface of a body. The lower surface of the retainer lugs and the tipper surface of the body lugs have non-planar surfaces which cam off of each other when the retainer is inserted into the body. The shock force from a weighted nozzle stem is transmitted through the lug system to the body and a surrounding pipe.
