摘要： A well head lubricator assembly including an elongated rigid tubular body defining an interior chamber open at a lower end to receive a plunger at a well head. The plunger is slidably positioned within the chamber in response to forces or loads acting thereon and has a seat arranged toward an upper end thereof. An upper end of the tubular body is closed. An axially elongated one-piece thermoplastic ether ester elastomer spring is slidingly positioned within the interior chamber of the tubular body. One end of the spring is seated on the seat of the plunger. The spring defines an elongated bore opening to opposed ends thereof. Moreover, the spring is provided with a plurality of axially spaced flange sections along a length thereof for guiding the spring for endwise sliding movement on an inside diameter of the tubular body. Any two flange sections on the spring are axially separated by an energy absorbing section for allowing the spring to react to energy imparted to the plunger. Each energy absorbing section on the spring defines a wall having a lateral thickness ranging between about 20% to about 30% of an axial length of the energy absorbing section extending axially between any two adjacent flange sections and such that radial expansion of the energy absorbing sections is limited to about an outermost edge of the flange sections.

摘要： An elastomeric compression including an elastomeric body defining a longitudinal axis and having two hollow convolutions between opposed ends of the spring. The convolutions are integrally formed and joined to each other by a connecting section. Each hollow convolution includes wall structure defining an outer surface for the spring. The wall structure of each convolution includes two angled wall sections disposed to opposed sides of the axis and which angle away from the connecting section and from each other. The outer surface of that portion of each angled wall section of each convolution adjacent to the connecting section has a projection extending outwardly from the outer surface. As such, and when the angled wall sections of one convolution collapse toward the angled wall sections of the other convolution, in response to a load being directed against the spring, the opposed projections on the convolutions contact and engage with each other thereby enhancing performance characteristics of the spring.
