Oil supply system for engine equipped with cvvt

Abstract

The present disclosure provides an oil supply system for an engine equipped with a Continuous Variable Valve Timing (CVVT) that includes: a camshaft having an internal space; and a lock pin that is unlocked from a lock pin hole by oil supplied from the internal space of the camshaft through an oil channel formed in a CVVT.

What is claimed is: 
     
         1 . An oil supply system for an engine equipped with a Continuous Variable Valve Timing (CVVT), comprising:
 a camshaft comprising an internal space; and   a lock pin configured to be unlocked from a lock pin hole by an oil supplied from an internal space of the camshaft through an oil channel formed in the CVVT.   
     
     
         2 . The oil supply system according to  claim 1 , wherein the internal space of the camshaft extends and communicates with the CVVT, thereby forming an oil channel reaching the lock pin. 
     
     
         3 . The oil supply system according to  claim 1 , wherein an Oil Control Valve (OCV) is disposed between the camshaft and the CVVT, and the internal space of the camshaft, the OCV, and the CVVT communicate with each other by a single oil channel. 
     
     
         4 . The oil supply system according to  claim 1 , wherein a bolt valve comprising an oil passage configured to communicate with the camshaft and the OCV and configured to supply an oil flowing inside to the lock pin through an oil hole formed in a side is disposed in the oil channel. 
     
     
         5 . The oil supply system according to  claim 4 , wherein an outer diameter of the bolt valve is the same as an inner diameter of the oil channel. 
     
     
         6 . The oil supply system according to  claim 4 , wherein a spool is disposed in the bolt valve, and
 when a current is supplied to an electronic actuator, the spool is operated, oil supplied from the camshaft is supplied to the lock pin through a gap between an outer side of the bolt valve and the spool, and the lock pin is unlocked.
