The present invention is a vacuum pressure generated by the breast milk of the mother to the reciprocating motion of the piston (negative pressure), the vacuum pressure (negative pressure) occurring in a device that milking milk automatically from the mothers breast piston forward and backward movement by using the collecting vacuum (-) relates to a high efficiency electric breast milking times the pressure generating capability, motorized breast milking machine according to the invention is a motor unit for generating a power source to convert the rotary motion of the motor to a linear reciprocating motion Double-acting cylinder type pump unit for reciprocating the piston by generating vacuum pressure (negative pressure) and air pressure (positive pressure) Vacuum pressure generated in the cylinder (pressure) and air pressure (positive pressure) of the cylinder before the four reverse flow, separated by a valve pressure between homeopathic After mounting [vacuum pressure (negative pressure), air pressure (positive pressure) each separated to connect the the two combined pressure pipe connected to the unit Vacuum pressure (negative pressure) to give a quarter of vacuum pressure (negative pressure) in two minutes inlet pressure to be milked simultaneously in both breasts using donated Pressure sum acid and pressures minutes to connect to the ends of the hose branched hose from the middle portion connected between the contributions to open and close the inlet atmospheric pressure valve in a short moment by the force of the electromagnet destroy the vacuum pressure (negative pressure) and help prevent re-operation the solenoid valve unit Control unit configured to electronic components such as a microcomputer and the operation switch for storing a program to be selected the motor operation and the driving state Pressure regulating unit consisting of a rotary pressure regulator connected to the branching portion to control the vacuum pressure (negative pressure)
