摘要:
A system for lubricating a valve assembly of an engine. The system includes a valve bridge having a base portion is disposed on a guide rod. The guide rod is received within a hole defined in the base portion of the valve bridge to define a chamber and to receive lubricant in the chamber. The valve bridge includes an arm that is engaged with a valve stem. The valve bridge includes a passage in fluidly communicating with the chamber and an end of the arm. The system includes a valve disposed around the valve stem and valve stem guide. The valve seal includes a lip member that abuts an outer surface of the valve stem to control a flow of the lubricant from the passage to a gap defined between the valve stem and the valve stem guide.
