  • Publication number: 20090097995
    Abstract: A syringe pump is disclosed, which uses the linear actuator applying a linear motion of a piezoelectric linear motor in moving the piston, such that suction and exhaustion of the fluid can be performed more precisely through controlling of power supply with respect to the piezoelectric linear motor. The syringe pump includes a cylinder which includes a receiving space, a piston which is mounted in the cylinder to pump liquid or powder in and out of the cylinder, and a piezoelectric linear actuator which moves the piston in a reciprocating manner. In addition, the piezoelectric linear actuator comprises a piezoelectric linear motor.
