Abstract

Provided are an oil-feeding member by which excess supply of lubricating oil from the oil-feeding member to a lubricated part of a valve mechanism can be prevented, and a lubricating-oil-supplying mechanism for an engine comprising the oil-feeding member. An oil-feeding member for supplying lubricating oil to a lubricated part of a valve mechanism (30) for opening / closing an intake valve (31B) and an exhaust valve (31A) of an engine (1), wherein: the oil-feeding member comprises an upper-side plate member (110) and a lower-side plate member (120) superimposed on each other, and an oil-feeding channel (102) formed by indenting the superimposed surfaces of the upper-side plate member (110) and the lower-side plate member (120); and the oil-feeding channel (102) includes a foundation oil channel (150) formed in the downstream side, and an inlet oil channel (130) formed in the upstream side, the inlet oil channel (130) having less area of lubricating oil flow than does the foundation oil channel (150).

Description

technical field [0001] The present invention relates to a technology of an oil supply member that supplies lubricating oil to a lubricating portion of a valve train that opens and closes intake and exhaust valves of the engine, and a lubricating oil supply mechanism for an engine including the oil supply member. Background technique [0002] Conventionally, an oil supply member that supplies lubricating oil to a lubricating portion of a valve train that opens and closes intake and exhaust valves of the engine and a lubricating oil supply mechanism for an engine including the oil supply member are known. lubricating oil. For example, as described in Patent Document 1. [0003] Patent Document 1 describes an oil supply member (shower pipe) mounted on a cylinder cover of a cylinder head of an engine. The oil supply member is provided with: an oil supply port through which lubricating oil is supplied; and a plurality of discharge ports through which lubricating oil is discharg...
