Abstract

Pulsation damping device for hydraulic installation provided with a rigid casing that has two opposite holes, a first and a second fitting mounted respectively in the aforementioned holes to connect the damper to the hydraulic installation, a flexible separator in the form of a bladder with two associated mouths respectively to said fittings, said separator defining in said envelope an interior compartment and an exterior compartment of variable volumes of a tube that has a longitudinal passage to interconnect said connections and a permeable lateral wall to communicate said passage with the said internal compartment, and a third fitting of fluid under pressure on the casing that communicates with said external compartment for damping pulsations, a damper characterized in that at least one of the ends of the tube is slidingly mounted.
