Abstract
First and second collars cooperate with first and second seal members separated by a retaining ring assembled onto a valve piston. The collars selectively engage the valve housing at one end and the retaining ring at the other end to limit the travel of the piston between first and second positions. Moreover, the assembly offers a cost effective alternative to the bonded rubber seals provided on known piston arrangements.
