FLUID-OPERATED ANTIVIBRATION MOUNT OF POWER UNIT Russian patent published in 2013 - IPC F16F13/06 

FIELD: machine building.

SUBSTANCE: proposed mount comprises working and compensation chambers filled with damping fluid and confined by support plate, resilient ring and resilient membrane, and conical equifrequent resilient element with screen damper. Resilient element comprises two resilient inner and outer rings arranged axisymmetric in parallel planes. Said rings are rigidly connected by two symmetric flexible diametrically opposite elements with through central groove made symmetrically inside said element. Groove side surfaces are connected with those formed by through holes arranged at said inner and outer rings.

EFFECT: better damping properties, longer life and lower noise.
