Abstract
A plunger mechanism has an internal shock absorber apparatus that operates to absorb shock during plunger fall and rise, thereby promoting a more reliable plunger lift system. The present apparatus can be used in well applications with or without a bumper spring. With the added reliability of the present system, well applications could be implemented such that fewer restrictions are encountered by a plunger at the well bottom. In addition, added reliability can help reduce plunger damage, whereby plunger life can be extended. Similarly, the present apparatus can minimize damage and extend the life of well components.
