Title:
Done type Liquid seal mount of a handstand
Document Type and Number:
Japanese Patent JP6073012
Kind Code:
B2
Abstract:
Annular liquid chamber resonance in an inverted type liquid sealed mount is controlled without using flow resistance. In an engine mount including a secondary liquid chamber located in an upper position, a primary liquid chamber located in a lower position, a main body section of an insulator projecting upwardly in substantially a chevron shape, and an annular liquid chamber formed around the main body section, a control projection is provided on an outside wall of the main body section to project upwardly and configured to produce elastic body resonance in the vicinity of a resonance frequency of annular liquid chamber resonance. With this construction, the annular liquid chamber resonance is controllable by the elastic body resonance of the control projection, and the control projection is increased in size so as to endure flow resistance whereby to improve durability.
