Definitions

  • first downstream branch oil passage 127 and the second downstream branch oil passage 128 will be described in detail below.
  • the coupling portion 140 couples the upper body 120 and the lower body 130 to each other.
  • the coupling portion 140 couples the right end of the upper body 120 and the left end of the lower body 130 at four positions.
  • the coupling portion 140 is integrally formed with the upper body 120 and the lower body 130.
  • a part of the oil feed member 100 (the part in which the upper through hole 121 and the lower through hole 131 are formed) is housed inside the exhaust-side recess 62 of the cam cap 50.
  • the upper through hole 121 and the lower through hole 131 of the oil feed member 100 overlap the exhaust-side through hole 64 of the cam cap 50 in the up-down direction.
  • the flow passage cross-sectional area (the area of the cross section perpendicular to the flowing direction of lubricant in the oil passage) of the first upstream branch oil passage 125 is smaller than the flow passage cross-sectional area of the basis oil passage 150 (more specifically, a part of the basis oil passage 150 except the slightly curved front-back middle part).
  • the first downstream branch oil passage 127 is an oil passage for guiding lubricant guided from the first upstream branch oil passage 125 to the discharge ports 134a and 134b.
  • the first downstream branch oil passage 127 is formed between the first upper and lower through holes 121, 131 from the front and the second upper and lower through holes 121, 131 from the front in the front-back direction.
  • the flow passage cross-sectional area of the first downstream branch oil passage 127 is smaller than the flow passage cross-sectional area of the first upstream branch oil passage 125.
  • the length, the shape, and the flow passage cross-sectional area of the second upstream branch oil passage 126 are one embodiment of the pressure loss generating mechanism according to the present invention.
  • a seal member such as a gasket may be interposed between the facing panel members.
  • the present invention is not limited thereto.
  • the pressure loss generating mechanism according to the present invention may be configured by making at least one of the length, the shape, and the flow passage cross-sectional area of the second upstream branch oil passage 126 different from at least one of the length, the shape, and the flow passage cross-sectional area of the first upstream branch oil passage 125.
  • the length, the shape, and the flow passage cross-sectional area of the second upstream branch oil passage 126 are not limited to those of the present embodiment, and may be determined in any manner.
  • the pressure loss generating mechanism when at least one of the length, the shape, and the flow passage cross-sectional area of the second upstream branch oil passage 126 is made different from at least one of the length, the shape, and the flow passage cross-sectional area of the first upstream branch oil passage 125, it is desirable to first make the flow passage cross-sectional areas different from each other to largely adjust the amount of flowing lubricant, and then make the lengths different from each other to finely adjust pressure loss generated in the lubricant.
  • Such a configuration makes it possible to further equalize the amount of lubricant discharged from the plurality of discharge ports 134. Further, it is possible to easily equalize the amount of lubricant discharged from the plurality of discharge ports 134.
  • the upper cut-away portion 233 and the upper face of the lower body 130 face each other and overlap each other in plan view.
  • a space defined by the upper cut-away portion 233 and the upper face of the lower body 130 in this manner is formed as an oil passage through which lubricant can flow.
  • the oil feed member 200 formed in this manner is attached to the inner side of the cylinder head cover 20. More specifically, as illustrated in Fig. 16 , a bolt 280 is inserted into the upper through hole 121 and the lower through hole 131 of the oil feed member 200 from the lower side and fastened to the cylinder head cover 20. In this manner, the oil feed member 200 is fixed to the inner side of the cylinder head cover 20 by fastening with the bolt 280.
  • lubricant fed to the oil feed member 200 is guided into the basis oil passage 150 through the upper cut-away portion 233.
  • the lubricant guided to the basis oil passage 150 is guided to the upstream branch oil passages 123 (the first upstream branch oil passages 125 and the second upstream branch oil passages 126) from the basis oil passage 150.
  • the lubricant guided to the upstream branch oil passages 123 (the first upstream branch oil passages 125 and the second upstream branch oil passages 126) is guided to the downstream branch oil passages 124 (the first downstream branch oil passages 127 and the second downstream branch oil passages 128) from the upstream branch oil passages 123.
  • the lubricant guided to the downstream branch oil passages 124 is discharged downward from the discharge ports 134.
  • an oil feed member 300 which is attached to the cylinder head cover 20 and includes oil passages for feeding lubricant to the intake-side and exhaust-side lubrication portions of the valve gear 30 will be described as a third embodiment with reference to Figs. 20 and 21 .
  • the basis oil passage 330 is an oil passage to which lubricant fed to the oil feed member 300 is first guided through the oil feed port 310.
  • the basis oil passage 330 linearly extends in the front-back direction from the front end through the back end of the oil feed member 300.
  • the front end of the basis oil passage 330 extends leftward and is connected to the oil feed port 310.
  • the second downstream branch oil passage 352 branches off from the second upstream branch oil passage 342, extends in the front-back direction, and is then bent to extend leftward. That is, the second downstream branch oil passage 352 is formed in a U-shape in plan view.
  • the second discharge ports 322a, 322b are connected to the respective ends of the second downstream branch oil passage 352.
  • the length between a connection point with the second upstream branch oil passage 342 and each of the second discharge ports 322a, 322b in the second downstream branch oil passage 352 is longer than the length between a connection point with the first upstream branch oil passage 341 and each of the first discharge ports 321a, 321b in the first downstream branch oil passage 351. This enables lubricant flowing through the second downstream branch oil passage 352 to have a larger pressure loss than lubricant flowing through the first downstream branch oil passage 351.
  • the fourth downstream branch oil passage 354 branches off from the fourth upstream branch oil passage 344, extends in the front-back direction, and is then bent to extend leftward. That is, the fourth downstream branch oil passage 354 is formed in a U-shape in plan view.
  • the fourth discharge ports 324a, 324b are connected to the respective ends of the fourth downstream branch oil passage 354.
  • the length between a connection point with the fourth upstream branch oil passage 344 and each of the fourth discharge ports 324a, 324b in the fourth downstream branch oil passage 354 is longer than the length between the connection point with the third upstream branch oil passage 343 and each of the third discharge ports 323a, 323b in the third downstream branch oil passage 353. This enables lubricant flowing through the fourth downstream branch oil passage 354 to have a larger pressure loss than lubricant flowing through the third downstream branch oil passage 353.
