This invention discloses a cartridge-type refrigerant solenoid valve structure for automobiles, comprising a magnetic conductor, a coil, a stationary iron core, a moving iron core, a valve body, and a piston. The magnetic conductor is fitted around the coil, and the stationary iron core is fixedly connected to the magnetic conductor. A sleeve fixedly connected to the stationary iron core is located in the middle of the coil. The moving iron core is located inside the sleeve below the stationary iron core, and a return spring is provided between the moving iron core and the stationary iron core. A connecting sleeve fixedly connected to the sleeve is located below the magnetic conductor, and a valve body with the same inner diameter as the connecting sleeve is fixedly connected to the bottom of the connecting sleeve. The piston is located inside the connecting sleeve, and a pilot hole is provided on the piston. A support spring is provided between the piston and the bottom surface of the valve body. This invention controls the energization of the solenoid coil, attracting the moving iron core in the valve body to move up and down, forming a pressure difference between the upper and lower chambers of the piston, which in turn drives the piston to move up and down. The structure is reasonably designed, highly sensitive, and can significantly improve valve opening performance.
