The simulation model and measurement results of pressure changes in the inter teeth volume has been presented. Based on simulation results an additional volume has been obtained, which is connected to the inter teeth volume (decompression filter volume). Due this additional volume the build down processes in the pump are longer and the pressure overdue in the inter teeth volumes are smaller. This leads to the reduction of the dynamical excitation forces inside the pump and noise, especially in the higher frequency rangeI.}, type={Artykuły / Articles}, title={Influence of the Inter Teeth Volumes on the Noise Generation in External Gear Pumps}, URL={http://ochroma.man.poznan.pl/Content/101453/PDF/12_paper.pdf}, doi={10.2478/aoa-2014-0030}, keywords={gear pumps, noise reduction, simulation, inter teeth volume}, }
