Abstract
A method of displacing a pumping assembly. In a first step, a first current is applied in a first direction through a coil assembly to displace a drive assembly from an initial position to cause a first pumping motion. Then, the drive assembly is returned to the initial position to cause a second pumping motion. At some point nearing the end of the second pumping motion, a second current is applied in the first direction through the coil assembly to decelerate the drive assembly before it reaches the initial position. A third current may be applied in a second direction through the coil assembly to cause or assist a return of the drive assembly to the initial position. An apparatus capable of carrying out the method is also disclosed.
