HYDRAULIC VIBRATION ISOLATING SUPPORT Russian patent published in 2007 - IPC F16F13/00 F16F9/08 

FIELD: mechanical engineering; transport engineering.

SUBSTANCE: invention is designed for suppressing vibrations of vehicle power units. Proposed hydraulic vibration isolating support contains working and compensating chambers filled with damping liquid and limited by support plate, elastic shell and diaphragm and also common housing with dividing partition with at least one inner space and throttling channels for communication with chambers. Inner space is made spherical and tangentially adjoining throttling channels provided with tangential outlets into chambers. Each throttling channel for communication with one of chambers is provided with throttling channel for communication with other chamber corresponding by geometric characteristics. Base attached to lower flange of housing is made in form of ring plate connected with round disk by at least three ribs. Conical elastic member is secured on round disk, being made of elastomer whose rigidity is equal to rigidity of elastic diaphragm.

EFFECT: improved suppression characteristics, increased service life of hydraulic support, reduced noise of vehicle power units in operation.
