PURPOSE:To control electrically a fluid of liquid with a fluid control valve of simple construction by driving a valve body with a piezo-element deformable through the application of voltage. CONSTITUTION:An oil passage 11 is provided with a poppet 13 via a piezo- element 12. This poppet 13 shuts off said oil passage 11 by coming in contact with a valve seat 14 provided therein, when the piezo-element 12 has become maximum in length. This element 12 when not applied with voltage, takes a minimum thickness and the poppet 13 is off the valve seat 14, thereby allowing pressurized oil to fluid from an inlet port 15 to an outlet port 16 via the oil passage 11. |
