Valve opening/closing device for engine

Abstract

The present disclosure provides a valve opening/closing device for an engine which opens/closes two valves by rotation of one cam. In particular, the valve opening/closing device may make a lever motion by rotation of a cam so as to open/close valves. The valve opening/closing device may include: a body portion adapted to which a valve gap control device is mounted and an axis of a lever motion is positioned; an extended portion extended from the body portion toward the valve; and two valve contact portions respectively protruded to both sides from the extended portion so as to function to push the two valves.

What is claimed is: 
     
         1 . A valve opening/closing device of an engine configured to open and close valves by a cam, the valve opening/closing device comprising:
 a body portion to which a valve gap control device is mounted and an axis of a lever motion is positioned;   an extended portion extended from the body portion toward the valves; and   at least two valve contact portions respectively protruded to both sides from the extended portion so as to function to push the at least two valves, respectively.   
     
     
         2 . The valve opening/closing device of  claim 1 , wherein the valve opening/closing device is supported on three points by one valve gap control device and two valves. 
     
     
         3 . The valve opening/closing device of  claim 1 , further comprising a connecting portion formed to connect the at least two valve contact portions with each other. 
     
     
         4 . The valve opening/closing device of  claim 3 , wherein both ends of the connecting portion are bent toward an upper direction so as to be connected with the at least two valve contact portions. 
     
     
         5 . The valve opening/closing device of  claim 3 , wherein the at least two valve contact portions and the connecting portion are formed in flat. 
     
     
         6 . The valve opening/closing device of  claim 1 , further comprising blocking protrusions protruded toward a lower direction from the at least two valve contact portions which are respectively protruded to the both sides.
