Abstract

The invention discloses a high-precision automobile oil outlet valve connector. The high-precision automobile oil outlet valve connector comprises a front connector body, a rear connector body and a sealing mechanism, a connector nut is arranged on the front connector body, an annular protrusion I located in the connector nut is arranged on the circumferential face of the rear end of the front connector body, and an annular sealing groove is formed in the rear end of the annular protrusion I. The cross section of the annular sealing groove is in a C shape, a sealing mechanism connected with the annular protrusion I in a sealed mode is arranged at the front end of the rear connector body and comprises an annular protrusion II, a sealing piece and a pushing mechanism, and the annular protrusion II and the sealing piece located in front of the annular protrusion II are arranged at the front end of the rear connector body. Compared with the prior art, through the high-precision automobile oil outlet valve connector, the reliability of sealing connection can be improved, and the influence on the reliability and performance of a whole diesel engine is reduced.
