Abstract

A surge suppressor for dampening undesired pressure surges in a fluid handling system and using a tubular, elastomeric diaphragm disposed in a hollow chamber of a housing to separate the chamber into two isolated zones, one being exposed to the fluid exhibiting undesired pressure surges and the other being pressurized with a compressible fluid. This arrangement obviates problems caused by wrinkling or folding of the generally planar diaphragm used in prior art pulsation dampeners.
