ABSTRACT:
Apparatus for dampening pulsations in a fluid system has a radially expandable tube connected in the fluid system. A flexible outer shell surrounds the tube to form with the tube an annular chamber. The annular chamber is pressurized by a compressed gas or other fluid to dampen fluid pulsations that act upon the tube. Annular end caps connect the tube and the shell. At each end, the tube has an extension with a threaded connection to a bushing; the bushing has a threaded connection to the inner annulus of the end cap.
