20140212315 | HYPERBOLIC HORN FOR PULSATION FILTER DEVICE USED WITH GAS COMPRESSOR - A method and system for reducing pulsation in a gas compressor system. A side branch absorber, which may be installed on the lateral piping of either the suction or discharge side of the cylinders, has a hyperbolic horn at the input end. The hyperbolic horn in series with an inlet reducer substantially increases the mass reactance of the resonator and substantially reduces the resonator frequency or the required cavity volume for target resonator frequency. The horn is hyperbolic in the sense that it has a large diameter at the first end tapers to a smaller diameter near the second end. | 07-31-2014 |
20120144671 | GAS COMPRESSOR WITH PULSATION ABSORBER FOR REDUCING CYLINDER NOZZLE RESONANT PULSATION - A method for reducing pulsation effects associated with the compressor nozzle of a positive displacement compressor system. A pulsation absorber, having a design like that of a side branch absorber, is installed on the cylinder valve cap or on the cylinder nozzle. The acoustic dimensions and placement of the pulsation absorber are designed to reduce the amplitude of the pulsations associated with the peak resonant frequency of the compressor nozzle response. | 06-14-2012 |
20110243760 | Pressure Recovery Insert for Reciprocating Gas Compressor - A method of reducing pulsations in a reciprocating compressor system, the system having nozzles between cylinders and filter bottles of the compressor system, the nozzles attaching at ports of the cylinders and filter bottles. A special insert is designed to be placed in one or more of the nozzle. The insert is generally cylindrical, but has a narrowed throat, a flared inlet end, and a flared outlet end. The insert dimensions, such as the inner diameter of the throat and the distance from the throat to the outlet end are calculated to reduce pulsations as well as provide pressure recovery. | 10-06-2011 |
