Title:
LIQUID-SEALING TYPE VIBRATION CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2005/093284
Kind Code:
A1
Abstract:
A liquid-sealing type vibration control device, wherein a lower side mounting fitting (34) forming an air chamber (36) in the clearance thereof from a diaphragm (16) is formed of aluminum, the bottom wall part (34B) thereof is made thicker than peripheral wall part (34C) thereof, and the bottom wall part is connected to the peripheral wall part with an arc-shaped curved part (34D) to decrease the weight and increase the strength of the lower side mounting fitting (34). The thickness of the lower side mounting fitting (34) is gradually increased from the bottom wall part (34B) toward the curved part (34D), maximized at the curved part (34D), and then gradually decreased to the peripheral wall part (34C). Where the radius of curvature of the arc on the outside of the curved part (34D) in the axial cross section is Ro and the radius of curvature of the arc on the inside is Ri, Ro is positioned within the range of 1 to 1.4 times Ri.
