The invention relates to a car seat lumbar support system electromagnetic valve. The valve comprises a coil and a coil holder. The coil is wound on the coil holder. An air inlet and outlet pipe is arranged vertically at one end of the coil holder. An air exhaust outlet is formed in one end of the coil holder and located at one end of the air inlet and outlet pipe. A fixed iron core is axially inserted and fixed into the other end of the coil holder. A movable iron core is arranged in an inner cavity of the coil holder in a sliding mode in the axial direction. A first flow channel is arranged in the fixed iron core and axially penetrates through the interior of the fixed iron core. A spring is mounted in the first flow channel. One end of the spring abuts against one end of the movable ironcore. A first valve port is formed between the fixed iron core and the movable iron core. A second valve port used for sealing the air exhaust outlet is formed between the other end of the movable iron core and the coil holder. A gap formed between the movable iron core and the inner cavity of the coil holder is a second flow channel. Yoke iron connected with the coil holder is mounted on one side of the coil. The car seat lumbar support system electromagnetic valve is high in integration level, exquisite in mechanism and small in size, and the one valve can meet air inflation, pressure maintaining and air relief function requirements of an air bag.
