The compressor can be used for refrigeration, engines, gas transportation, chemical processes, mechanical manufacturing, aquaculture, medical treatment, and almost all places where compressed gas needs to be transported or used. However, when the existing compressor operates, a motor drives a cam to convert it into a linear motion of the piston connecting rod inside the compressor. However, when the cam rotates once, the piston connecting rod can only reciprocate once, and the stroke is determined by the eccentricity of the cam. When a large stroke is required, the entire mechanism will be very large. Therefore, a cross-opposed compressor is proposed. Content of the Utility Model
