Variable-displacement SE series compressor and airflow pulse stabilizing valve thereof

The invention discloses a variable-displacement SE series compressor and an airflow pulse stabilizing valve thereof. The variable-displacement SE series compressor comprises a shell, a cylinder body,a rotating shaft, a variable-displacement driving device, a rear cover, a front cover, a valve plate, an air inlet valve port and an air outlet valve port, wherein the cylinder body is integrally formed at one end of the inner wall of the shell, and six compression chambers are formed in the cylinder body at equal intervals; the rotating shaft is rotationally connected to the middle of the cylinder body through a bearing; and the variable-displacement driving device is arranged at one end of a main shaft. By means of an air intake and exhaust device, half of the piston displacement can be reduced, and conflict between the air intake and exhaust device and the variable-displacement driving device is avoided. Torque required for driving the rotating shaft can be reduced by reducing work of apiston, torque power sepa
