Abstract
PURPOSE:To enhance the shutoff effect for input vibration by furnishing a blocked pipe in the condition the opening part opens to a pressure receiving chamber, and allowing blocking end of the blocked pipe to reflect the pressure wave, which is generated by non-compressive fluid in the pressure receiving chamber and transmitted into the blocked pipe. CONSTITUTION:When input vibration generates pressure wave in a non- compressive fluid inside a pressure receiving chamber 24, the wave is transmitted to a non-compressive fluid in a blocked pipe 30 and, upon being reflected by the bottom wall 34 of the blocked pipe, returned to the pressure receiving chamber 24 with phase lag corresponding to the length of the blocked pipe 30. Accordingly the pressure wave in the pressure receiving chamber 24 receives interference of the reflex wave from the blocked pipe 30, and the amplitude will lessen in a frequency range corresponding to the length of the blocked pipe 30. That is, the absolute spring constant is reduced effectively in the frequency range in which the amplitude of the pressure wave lessens. Consequently the input vibration can be shut off effectively in the frequency range in which the amplitude of the pressure wave lessens.
