−人家２とは遮断されるように構成されている。The primary chamber 2 and the secondary chamber 3 are communicated through a valve opening 6 controlled by a valve 7. The sliding body 7' of the valve 7 connects the piezoelectric elements 9a, 9b, the fixing member 8a,
8b, supported by the body 17. A high frequency voltage is applied from an external drive circuit 15 to the electrodes 12a, 12b, 13a, 13b of the piezoelectric elements 9a, 9b.
1a and 11b. 16 is a high frequency voltage generator. The valve back chamber 15 is configured to be communicated with the tertiary chamber 3 through a force introduction path 8 provided in the valve, and to be cut off from the tertiary chamber 2.
