ABSTRACT:
Disclosed is an improved surge stabilizer for reducing and controlling pressure surges and vibrations which cause destructive wear to pumps. The stabilizer includes a cylindrical case which is placed in pressure communication with the pump working fluid, and an internal pressurizable cylindrical cartridge having a flexible sidewall and end caps, one of which is attached to one end of the case. A control rod is slidingly fitted in bores in the caps, thereby eliminating the tendency of the cartridge to "piston" longitudinally. Further control of the compression characteristics of the cartridge is obtained by providing multiple plies of equal length in the sidewall of the cartridge, and by utilizing reinforcing cords in the plies wrapped at a selected bias or angle.
