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.
Claims14
Apparatus for damping pulsations in a fluid system in which a vibration generating component is connected, the apparatus comprising:
- a radially expandable tube connected in the fluid system;
- a flexible corrugated outer shell surrounding the tube to form with the tube an annular chamber, the outer shell retaining its shape and diameter under pressure;
- and
- a fluid source pressurizing the annular chamber to dampen fluid pulsations generated by the component and isolate the component from the remainder of the fluid system.
