HYDRAULIC VIBRATION SUPPORT (VARIANTS) Russian patent published in 2003 - IPC

FIELD: mechanical engineering; vibration isolation supports for dampening vibrations; installation of internal combustion engines in automobiles. SUBSTANCE: proposed hydraulic vibration support includes fastening member, working and compensating chambers filled with dampening fluid and bounded by common housing with dividing partition secured in it and with at least one throttling passage communicating said chambers and diaphragm. Used as dividing partition is flexible load-bearing member with fastening member secured in it. Working chamber is bounded by diaphragm and compensating chamber is bounded by bottom of housing. Housing is provided with cover having opening for fastening member. According to first variant, load-bearing flexible member is made integral from rubber elastic material and according to second variant, peripheral part of load-bearing member is made from rubber elastic material and central part is made from two polyamide washers with L- shaped passages. EFFECT: simplified construction; facilitated assembly; enhanced maintainability with no impairment of quality parameters. 13 cl, 5 dwg
