ABSTRACT:
A hydraulic pulse dampener of liquid compressibility type has a flexible tubing wound around a form within a liquid-tight housing filled with a compressibility liquid and a stiff diaphragm placed adjacent a recess formed in a receiving member. As the fluid flowing inside the tubing experiences pressure pulses, the walls of the tubing expand and transmit the pulse energy through the compressibility liquid and causes the diaphragm to gradually flex towards the recess until it may completely nest in it. The recess in the receiving member preferably has a central flat portion so that the flexing diaphragm will first contact the receiving member at the center and the nesting will spread outwardly therefrom.
