Abstract
The invention discloses a valve ejector rod with a lubricating oil filtering groove. The valve ejector rod comprises an ejector rod body. One end of the ejector rod body is provided with an ejector pin. The other end of the ejector rod body is provided with an ejector cap. The ejector cap is a cap cover body, wherein the interior of the cap cover body is a cavity. The front end of the ejector cap is a horizontal sealing face. The rear end of the ejector cap is an arc sealing face. An oil outlet is formed in the center of the arc sealing face of the rear end of the ejector cap. An oil discharge groove is formed in the ejector rod body. One end of the oil discharge groove is connected to the oil outlet. The other end of the oil discharge groove is guided out of the ejector pin. By means of the manner, the ejector cap is set to be of the lubricating oil storage type, lubricating oil can be discharged continuously when the valve ejector rod works, the lubricating property of the valve ejector rod is improved, and the service life is prolonged.
