Embodiment Construction

[0049] Next, the up-down direction, the left-right direction, and the front-rear direction are defined according to the arrows shown in the figure.

[0050] First, use Figure 1 to Figure 3 The structure of the engine 1 provided with the oil supply member 100 and lubricating oil supply mechanism which concerns on one Embodiment of this invention is demonstrated.

[0051] The engine 1 of the present embodiment is a 4-cylinder, 16-valve DOHC (Double Overhead Camshaft) gasoline engine in series. Hereinafter, for the sake of convenience of description, the description will mainly focus on one cylinder (specifically, the second cylinder from the front) among the four cylinders arranged in the front-rear direction. The engine 1 mainly includes a cylinder head 10 , a cylinder head cover 20 , a valve train 30 , a cam cover 50 , and an oil supply member 100 .

[0052] figure 1 and image 3The illustrated cylinder head 10 serves as a main structural body of the engine 1 together wit...

Abstract

The present invention provides an oil feeding member capable of securing a wide interval between oil passages and achieving a reduction in space of the oil passages, and an engine lubricating oil supply mechanism provided with the same. An oil feeding member (100) is provided with a lubricating oil passage and a plurality of ejection ports (134) that is formed on a downstream side end portion of the lubricating oil passage and that ejects lubricating oil, having flowed through the lubricating oil passage, toward a lubricating portion, wherein the lubricating oil passage includes: an essential oil passage (150); a first upstream side branched oil passage (125) branched from the essential oil passage (150) and in which the lubricating oil being guided to two ejection ports (134a, 134b) out of the plurality of ejection ports (134) flows; and a second upstream side branched oil passage (126) branched from the essential oil passage (150) and in which the lubricating oil being guided to two ejection ports (134c, 134d) out of the plurality of ejection ports (134) flows.

Description

technical field [0001] The present invention relates to a technique of an oil supply member for supplying lubricating oil to a lubricating portion of a valve train that opens and closes intake and exhaust valves of an engine, and an engine lubricating oil supply mechanism including the oil supply member. Background technique [0002] Conventionally, an oil supply member for supplying lubricating oil to a lubricating portion of a valve train that opens and closes intake and exhaust valves of an engine and a lubricating oil supply mechanism for an engine including the oil supply member are known. For example, as described in Patent Documents 1 and 2. [0003] Patent Document 1 describes: a cylinder head having a bearing portion; a camshaft rotatably supported by the bearing portion; and a cam cover fixed to the cylinder from above so as to sandwich the camshaft. a cover; and a cam injection pipe (an oil supply part) connected to an upper portion of the cam cover. In addition...
