APPARATUS AND METHOD FOR RETARDING TRANSLATION BETWEEN TWO BODIES

摘要

Disclosed is a rod brake (30), and a method, including an elastic device, such as a coil spring (44), array of split rings (58), or an elastic sleeve (102), that engages one or more grooves (38) in a cylindrical surface to restrain the rod (34) from longitudinal movement relative to another body (32), and wherein longitudinal force is applied to distort the elastic device and push it out of the one or more grooves to release the rod for longitudinal movement. A locking sleeve (48) is added to lock the elastic device against distortion and movement to the release configuration.
