A hydraulically damped rubber motor mount has a mounting flange, a motor connection above the flange, and a rubber annulus interconnecting the connection and flange and forming a hydraulic chamber. An elastically expansible and contractible hydraulic enclosure is connected with the chamber via a flow path that is at least fifty times longer than its cross-sectional area. Hydraulic fluid fills the chamber, enclosure and path. Low frequency vibration applied to the motor connection when supporting a motor, is damped by hydraulic flow back and forth between the chamber and enclosure via the flow path. Because of the length of this flow path relative to its cross-sectional area, the mount does not excessively stiffen when the motor applies high frequency vibration to the motor connection. |
