Patent ID: 10465832

Abstract:
A damping device, in particular for damping or preventing pressure impacts, like pulsations, in hydraulic supply circuits has a damping housing (1) surrounding a damping chamber with a fluid inlet (13) and a fluid outlet (15). A damping tube (21; 51) is located in the flow path between the damping inlet and outlet and has a branch opening (29; 73, 75, 77, 79, 81) passing through the tube wall and leading to a Helmholtz volume (27; 53, 55, 57, 59, 61) inside of the damping housing (1) forming a Helmholtz resonator in a region positioned inside of the length of the damping tube. A fluid filter (35) is arranged inside of the damping housing (1) in the flow path between the fluid inlet (13) and fluid outlet (15).
