Abstract
A pulsation dampener useful to dampen pressure pulsations in milk flowing between a reciprocating-piston pump and a homogenizer. A rigid tube having a perforated portion is surrounded by an elastomeric sleeve. A rigid sleeve surrounds the elastomeric sleeve. Mounting ferrules are welded to opposite ends of the rigid sleeve. Annular beads at opposite ends of the elastomeric sleeve fit into annular grooves in the mounting ferrules. When matching ferrules are clamped tightly to the mounting ferrules, parts of the elastomeric sleeve are displaced, so as to form seals around the rigid tube. The rigid tube, the mounting ferrules and the elastomeric sleeve respectively are configured so as to permit the rigid tube to be axially withdrawn from or inserted into the elastomeric sleeve, without substantial interference, when the matching ferrules are removed.
