Title:
FLUID SEALING TYPE VIBRATION CONTROL DEVICE
Document Type and Number:
Japanese Patent JP2018155332
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a fluid sealing type vibration control device with a novel structure, capable of attaining excellent vibration control performance with a simple and compact structure.SOLUTION: A fluid sealing type vibration control device 10 is configured such that a pressure receiving chamber 70 where incompressible fluid is sealed, and a balance chamber 72 communicate with each other in an orifice passage 74; provided is a relief mechanism 62 configured to open a short-circuiting passage 77 by negative pressure occurring in the pressure receiving chamber 70 due to input of impulsive load, to communicate the pressure receiving chamber 70 to the balance chamber 72, thereby suppressing cavitation. At a portion of the short-circuiting passage 77 in the relief mechanism 62, provided is a leak passage 78 configured to maintain a communication state of the pressure receiving chamber 70 and the balance chamber 72 on a passage cross section smaller than the orifice passage 74 even in a state where the short-circuiting passage 77 is not opened.SELECTED DRAWING: Figure 1
