The invention discloses an electromagnetic valve, refrigeration equipment and an automobile. The electromagnetic valve comprises a valve body, a sleeve and a piston, and the valve body is provided with a valve cavity and a valve port communicated with the valve cavity; the sleeve is arranged on the valve body, and the sleeve is communicated with the valve cavity; the piston is movably arranged in the valve cavity at a valve opening position and a valve closing position, when the piston is located at the valve opening position, the valve port is opened, and when the piston is located at the valve closing position, the valve port is closed; the piston is provided with a main guide part and an auxiliary guide part, the main guide part is at least partially arranged in the valve cavity, and the auxiliary guide part is at least partially arranged in the sleeve; the main guiding part is in guiding fit with the cavity wall of the valve cavity, and the auxiliary guiding part is in guiding fit with the inner wall of the sleeve so that the piston can be guided when moving between the valve opening position and the valve closing position. The electromagnetic valve can solve the problem that the piston in the electromagnetic valve is easy to deviate during movement, so that the stability of the electromagnetic valve is improved.
