The invention provides a valve plate assembly and a compressor with the valve plate assembly. The valve plate assembly comprises a valve plate with an exhaust hole, a valve block connected with the valve plate and located on one side of the exhaust hole, and a limiter. The valve block has an avoiding position where the exhaust hole is opened and a closing position where the exhaust hole is closed.The limiter is connected with the valve plate, the valve block is located between the valve plate and the limiter, and part of the surface of the side, towards the exhaust hole, of the limiter is ofan arc face structure, so that when the valve block is located at the avoiding position, the head and the waist of the valve block are closely attached to the limiter. Through the arrangement, the problem that a limiter in the prior art is adopted, a valve block is unevenly stressed, and consequently the valve block is prone to fracture is solved. By adoption of the valve plate assembly of the structure, the reliability an
