記載の車輛の液封入防振装置。[Claims for Utility Model Registration] (1) A liquid that is installed in a vehicle and has first and second liquid chambers whose chamber walls are elastic bodies that deform due to vibration input, and a partition wall that partitions these liquid chambers. In the encapsulated vibration isolator, the partition wall is provided with a first liquid communication port that opens to the first liquid chamber, and a second liquid communication port that opens to the second liquid chamber, and A valve body provided with a small-diameter throttle flow path is disposed within the partition wall, and a valve drive means is provided, and the valve drive means operates the valve body according to the driving state of the vehicle to select one of the following. Specifically, the first and second liquid distribution ports are communicated directly, the first and second liquid distribution ports are communicated via the throttle channel, and the first and second liquid distribution ports are communicated with each other through the throttle channel. A liquid-filled vibration isolator for vehicles that isolates ports. (2) Two of the second liquid distribution ports are provided, one of which is provided at a position close to the first liquid distribution port, and the other is provided at a position farther from the first liquid distribution port, and the valve is driven. activating the valve body according to the operating state of the vehicle by means to alternatively cause direct communication between the first liquid distribution port and the one liquid distribution port; Utility model registration claim 1, wherein the other liquid distribution port is communicated through the throttle channel, and the first liquid distribution port is isolated from the one and the other liquid distribution ports. A liquid-filled vibration isolator for a vehicle as described in Section 1.
