ABSTRACT:
An electrical pump adapted for use with a piston rod in an air nozzle has an electromagnetic valve board with an electromagnetic valve thereon. A Z-shaped push rod is provided to be adapted to be driven by the electromagnetic valve so as to drive the piston rod to move accordingly. The movement of the Z-shaped push rod allows air from the electrical pump to be pumped into an object to be inflated/deflated when the motor is running depending on whether the inlet or the outlet is in alignment with the nozzle assembly of the nozzle assembly.
