Strainer for oil supply mouth

Abstract

The invention is an object of the invention to provide a strainer for an oil supply mouth, preventing the oil flowing when supplying the oil from colliding with the float so as to accurately detect the height of the liquid level. The strainer for an oil supply mouth of the invention has a guide hole equipped in vertical directions and a float for an oil level gauge passing movably in vertical directions through this guide hole. When the oil comes up to an at least reference liquid level, the float is received at a lower end within the guide hole.

1 . A strainer comprising: 
 a body;    a guide hole formed in a vertical direction through a body; and    a float for oil level gauge that passes movably in the vertical direction through the guide hole, wherein the float is received at a lower end within the guide hole when oil comes to an at least reference liquid level.    
     
     
         2 . The strainer according to  claim 1 , wherein when the float places at a lower part of the guide hole, a lower end of the float projects from the guide hole in the vertical direction.  
     
     
         3 . The strainer according to  claim 1 , wherein the guide hole includes a bottom portion for restraining the float from moving downward.  
     
     
         4 . The strainer according to  claim 1 , wherein a nozzle is projected from the body, and the guide hole is extended to a nozzle.  
     
     
         5 . A strainer for an oil supply mouth comprising: 
 a network part for filtering impurities;    a frame body for supporting the network part, that is formed to be substantially in a cup shape, and includes an opening at a upper part thereof;    a guide hole formed in a vertical direction through the frame body; and    a float for an oil level gauge which is inserted movably in the vertical direction within the guide hole.    
     
     
         6 . The strainer according to  claim 5 , wherein the guide hole includes an opening at the upper side, and the float is detachably inserted in the guide hole from the opening.  
     
     
         7 . The strainer according to  claim 5 , wherein the float includes, at the upper end, a stopper for contacting with an opening of the guide hole.
