素子を用いた弁。[Claims for Utility Model Registration] (1) Valve chambers 3 formed at both ends of a tubular valve body 2 provided slidably in the axial direction within the housing 1
, 4, there is a valve seat 5 at the axial position facing the valve body.
6 are arranged such that when one valve seat is in close contact with the valve body 1, the other valve seat is apart, and
A piezoelectric laminate 11 is fixed to the housing 1 in parallel with the valve body 2 in the central chamber 7 of the housing 1, and an L-shaped lever lever 12b that engages with the movable part of the piezoelectric laminate to increase displacement is provided on the outside. The lever lever 12b is connected to the lever lever 12b via an elastic link member 14 which is provided and changes the displacement of the driven end 12f of the lever lever into an axial movement of the valve element against the spring 15 biased against the valve element 1.
A valve using a piezoelectric element, characterized in that a valve body 2 and a valve body 2 are connected to each other. (2) Utility model registration claim 1, in which the support body 12a that fixes the piezoelectric laminate 11 to the housing 1 and the L-shaped lever lever 12b are integrally molded.
A valve using a piezoelectric element as described in . (3) The piezoelectric laminate 11 and the displacement magnifying mechanism are each 2
A valve using piezoelectric elements according to claims 1 and 2, which are arranged on one plane on both sides of a valve assembly 2.
