One-way valve seat assembly

The one-way valve seat assembly comprises a valve seat, a first oil through hole and a second oil through hole which are communicated with each other are coaxially formed in the two ends of the valve seat respectively, and a steel ball is arranged in the first oil through hole; a sealing surface is pressed at the communication part of the first oil through hole and the second oil through hole; an annular bendable part is formed in the position, located at an orifice of the first oil through hole, of the valve seat, and a plurality of limiting parts bent towards the interior of the first oil through hole are pressed at the end of the annular bendable part. According to the one-way valve assembly, the matching degree of the sealing face and the steel ball can be guaranteed through the pressed sealing face, the sealing effect of the steel ball is guaranteed, the steel ball is limited through the simplified steel ball limiting structure and the annular bendable part and the multiple limiting parts convenient to p
