HYDRAULIC VIBRATION SUPPORT Russian patent published in 1998 - IPC

FIELD: mechanical engineering; dampening vibrations in power units of transport facilities. SUBSTANCE: hydraulic vibration support includes working and compensating chambers filled with dampening liquid bounded by bearing plate, flexible ferrule and diaphragm as well by common housing provided with partition with at least one inner cavity and throttling passages for communication with chambers. Inner cavity is spherical in form; it tangentially adjoins throttling passages having tangential outlets to chambers. Each throttling passage of communication with one chamber has respective (according to geometric characteristics) throttling passage for communication with other chamber.
