Valve seat lubrication oil coating device

Abstract

Disclosed is a valve seat lubrication oil coating device. More specifically, an oil pan is filled with lubrication oil and configured so that a valve seat partially soaks therein. An oil tank is equipped with a hydraulic pump, and an oil pan oil supplier supplies oil to the oil pan via the hydraulic pump from the oil tank. Additionally, a coating oil supplier coats an outer circumferential surface of a portion of the valve seat, which is not being soaked in the oil, with the oil from the oil tank.

What is claimed is: 
     
         1 . A valve seat lubrication oil coating device comprising:
 an oil pan filled with lubrication oil and configured so that a valve seat partially soaks therein;   an oil tank equipped with a hydraulic pump;   an oil pan oil supplier configured to supply oil to the oil pan via the hydraulic pump from the oil tank; and   a coating oil supplier configured to coat the outer circumferential surface of a portion of the valve seat, which is not being soaked in the oil, with the oil from the oil tank.   
     
     
         2 . The device of  claim 1 , wherein the oil pan is formed in a semicircle in which the valve seat is placed. 
     
     
         3 . The device of  claim 2 , wherein the oil pan oil supplier includes:
 oil pan oil supply lines configured to supply the oil to the oil pan from the oil tank; and   oil exhaust lines configured to return the oil to the oil tank from the oil pan.   
     
     
         4 . The device of  claim 3 , wherein the oil pan oil supply lines are provided in a pair to communicate with both ends of the upper portion of the oil pan. 
     
     
         5 . The device of  claim 3 , wherein regulators are disposed in the oil pan oil supply lines to uniformly supply the oil. 
     
     
         6 . The device of  claim 3 , wherein the coating oil supplier includes:
 an oil coating device configured to apply the oil onto an outer circumferential surface of the portion of the valve seat which is not being soaked in the oil; and   a coating oil supply line configured to supply the oil to the oil coating device from the oil tank.   
     
     
         7 . The device of  claim 6 , wherein the oil coating device is equipped with a solenoid valve and configured to control the amount of oil that is applied to an outer circumferential surface of the valve seat. 
     
     
         8 . The device of  claim 6 , wherein the coating oil supplier further includes a regulator disposed in the coating oil supply line to uniformly supply the oil to the oil coating device. 
     
     
         9 . The device of  claim 1 , wherein the coating oil supplier includes:
 an oil coating device configured to apply oil to an outer circumferential surface of the portion of the valve seat which is not being soaked in the oil; and   a coating oil supply line configured to supply oil to the oil coating device from the oil tank.   
     
     
         10 . The device of  claim 9 , wherein the oil coating device is equipped with a solenoid valve and configured to control the amount of oil that is applied to an outer circumferential surface of the valve seat. 
     
     
         11 . The device of  claim 9 , wherein the coating oil supplier further includes a regulator disposed in the coating oil supply line to uniformly supply the oil to the oil coating device.
