Abstract
The invention provides an exemplary pulsation dampener which comprises a vessel which defines an interior for receiving a fluid. At least two resilient cartridges are disposed within the interior of the vessel. The cartridges are pressurized to different pressures so that they will dampen pressure pulses within the fluid which have different pressure peaks.
Claims7
A method for dampening pressure variations within a fluid that is flowed through a vessel, the method comprising:
- placing at least two resilient cartridges within the vessel, wherein the cartridges are pressurized to different internal pressures;
- flowing the fluid into the vessel;
- transmitting at least two pressure pulses which have different pressure peaks through the fluid, wherein one of the pressure pulses has a pressure peak that is greater than the internal pressure of both cartridges to cause both cartridges to flex and thereby dampen the pressure pulse, and wherein the other pressure pulse has a pressure peak that is between the internal pressures of the two cartridges to cause the cartridge with the lower internal pressure to flex and thereby dampen the pressure pulse having the smaller pressure peak.
