Abstract: Provided are a control valve structure and a compressor having same. The control valve structure comprises a valve body, said valve body having an accommodating chamber; a valve core (30) is movably arranged inside the accommodating chamber; a piston (40) is movably arranged inside the accommodating chamber; the valve core (30) drives the piston (40) in reciprocating motion in the axial direction of the accommodating chamber; a steering assembly (50); the valve core (30) is movably connected to the piston (40) by means of the steering assembly (50). The steering assembly (50) is arranged between the valve core (30) and the piston (40), such that the valve core (30) may move relative to the piston (40). Thus when the valve core (30) laterally drives or pushes the piston (40) to move, if the frictional force between either the valve core (30) or the piston (40) and the chamber wall of the accommodating chamber is excessively large, then a certain amount of longitudinal displacement of either the valve core (30) or the piston (40) is allowed so as to prevent the frictional force between either the valve core (30) or the piston (40) and the chamber wall from continuing to increase; thus the situation of the valve core (30) and piston (40) becoming stuck is prevented. The use of the described control valve structure effectively improves the reliability and usefulness of the control valve.
