LIQUID SEALING TYPE VIBRATION CONTROL DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a liquid sealing type vibration control device capable of improving assembling quality and reducing a cost with a simple structure by reducing the number of parts without damaging reliability of a product and sealing performance of sealing liquid. SOLUTION: A cylindrical rubber member 4 for forming an orifice and a diaphragm 5 are integrally formed. A partition member 7 is fitted into an internal circumference of the cylindrical rubber member to form an air chamber 8 between the diaphragm 5 and the partition member 7. The cylindrical rubber member 4 is pressed-in to the position where it is applied to a bottom portion 14 of a cylindrical body portion 11 of a body member 1, from the diaphragm side. An orifice 9 is formed between a groove portion 43 of an outer periphery of the clerical rubber member. Groove portions 43 on an outer periphery of the cylindrical rubber member form orifices 9 in an interval between the cylindrical body portion and the cylindrical rubber member. Between the diaphragm 5 and the bottom portion 14 of the body member 1, a liquid chamber 6a is formed. A reinforcing member 31 for a lower end of an outer periphery of the vibration control base body 3 is pressed in at an opening side of the cylindrical body portion 11 to pressingly fix an upper end of the cylindrical rubber member. An interval between the vibration control base body 3 and the partition member 7, a liquid chamber 6a is formed. Both of the liquid chambers communicate with each other through the orifices 9.
