Description
- The present invention relates to a lubricating oil passage structure in an internal combustion engine for supplying a lubricating oil to portions to be lubricated in the internal combustion engine.
- In an internal combustion engine, in general, to guarantee the smooth operation of the internal combustion engine, a lubricating oil passage for supplying a pressurized lubricating oil to portions to be lubricated such as rotating and sliding portions of the internal combustion engine is provided, and a constriction passage, i.e., a jet is provided in place in the lubricating oil passage to communicate with the latter, so that the pressurized lubricating oil flowing in the lubricating oil passage is ejected through the jet, and for example, the ejected lubricating oil is supplied to a back side of a piston to lubricate and cool the piston (for example, see
Japanese Patent Application Laid-open No.9-209733 - It should be noted here that even if the lubricating oil filtered by an oil filter flows in the lubricating oil passage, the following problem is encountered: It is inevitable that a foreign matter such as a small amount of a dust and cuttings is incorporated into the lubricating oil. The foreign matter may reach the inlet of the constriction passage, i.e., the jet provided in the lubricating oil passage, thereby occluding the inlet, and in such case, the amount and pressure of lubricating oil ejected from the jet are reduced.
- The present invention has been accomplished with such circumstances in view, and it is an object of the present invention to provide a new lubricating oil passage structure in an internal combustion engine, wherein the inlet of the jet cannot be occluded by the foreign matter.
- To achieve the above object, according to the present invention, there is provided a lubricating oil passage structure in an internal combustion engine, comprising a jet provided in place in a lubricating oil passage leading to an oil pump, so that a pressurized lubricating oil flowing in the lubricating oil passage is ejected toward portions to be lubricated through the jet,
characterized in that oil grooves are provided in an inlet of the jet to communicate with the jet, the oil grooves being opened into the lubricating oil passage and extending diametrically from the center of the jet. With such feature, the inlet of the jet is prevented from being occluded by a foreign matter such as a dust and cuttings incorporated in the lubricating oil, and the lubricating oil can be ejected always in an appropriate amount and under an appropriate pressure from the jet. - According to another aspect and feature of the present invention, in addition to the first arrangement, the oil grooves are cross-shaped grooves extending diametrically about the jet. With such feature, the inlet of the jet is prevented further reliably from being occluded by a foreign matter such as a dust and cuttings incorporated in the lubricating oil, and the lubricating oil can be ejected always in an appropriate amount and under an appropriate pressure from the jet.

Fig.1 is a sectional view of essential portions of an internal combustion engine provided with a lubricating oil passage structure according to the present invention;Fig. 2 is an enlarged view of a portion surrounded by a phantom circle indicated by anarrow 2 inFig. 1 ; andFig.3 is a partial view of a portion indicated by anarrow 3 inFig.2 . - The mode for carrying out the present invention will now be described by way of an embodiment shown in the accompanying drawings.
- First, an embodiment of the present invention will be described with reference to
Figs.1 to 3 . - Referring to
Fig. 1 , an engine body E of a 4-cycle internal combustion engine includes acylinder block 1 having acylinder bore 2 provided therein, acylinder head 3 which is fixed onto a deck surface of thecylinder block 1 and in which acombustion chamber 4 is defined to confront thecylinder bore 2, and acrankcase 5 fixed to a lower surface of thecylinder block 1. Anoil pan 6 is fixed to a lower surface of thecrankcase 5. - As usual, a
crankshaft 7 is rotatably carried within thecrankcase 5 with a ball bearing 8 interposed therebetween, and a connectingrod 10 is rotatably connected at its larger end to acrankpin 7a of thecrankshaft 7 through a needle bearing 11 and at its smaller end to apiston pin 13 of apiston 12 slidably received in thecylinder bore 2. - A lubricating system L is provided in the engine body E for lubricating various portions of the engine body E. The lubricating system L is of a conventionally known construction, and a
suction passage 16 connected to a suction port of anoil pump 15 connected to the lubricating system L is connected at its lower end to anoil strainer 17 immersed in a lubricating oil stored in theoil pan 6. Adischarge passage 18 connected to a discharge port of theoil pump 15 communicates with amain gallery 21 defined as a lubricating oil passage in thecylinder block 1. - A piston-lubricating
oil passage 24 defined in thecrankcase 5 communicate with an intermediate portion of themain gallery 21, and ajet 25 is opened into awall 24a of thepassage 24, which confronts thecylinder bore 2 and thejet 25 has an inlet communicating with the piston-lubricatingoil passage 24 and an ejecting outlet directed toward a back side of thepiston 12 within thecylinder bore 2. - As clearly shown in
Figs. 2 and 3 ,oil grooves 26 according to the present invention are provided at the inlet of thejet 25 to communicate with the inlet of thejet 25, and extend diametrically in a cross-shape about thejet 25, as shown inFig.3 . Sides of thecross-shaped oil groove 26, which confront the piston-lubricatingoil passage 24, are opened into the piston-lubricatingoil passage 24 over the substantially entire region of the latter. - In
Fig.1 ,reference character 28 is a lubricating oil passage defined in thecrankshaft 7;reference character 29 is a timing transmitting device for operating a valve-operating mechanism (not shown) in operative association with thecrankshaft 7;reference character 30 is a gear for driving the oil pump; andreference character 31 is a gear for driving a clutch leading to a transmission. - Next, the operation of this embodiment will be described below. If the
crankshaft 7 is now rotated by the operation of the internal combustion engine and theoil pump 15 is driven, the lubricating oil within theoil pan 6 is drawn via theoil strainer 17 and fed under pressure to themain gallery 21 defined as the lubricating oil passage in thecylinder block 1. - A portion of the pressurized lubricating oil flowing in the
main gallery 21 is supplied to the piston-lubricatingoil passage 24. The lubricating oil reaching thepassage 24 is ejected from thejet 25 directed to the back side of thepiston 12 as shown by an arrow a inFigs.1 and2 , and is supplied to the back side of thepiston 12 to lubricate and cool thepiston 12 and an inner wall surface of thecylinder bore 2. - The lubricating oil flowing in the
main gallery 21 is filtered by theoil strainer 17, but a portion of a foreign matter R such as a fine dust and fine cuttings may not be filtered off and may be fed through themain gallery 21 to the piston-lubricatingoil passage 24. The foreign matter R may occlude a center portion of the inlet of the small-diameter jet 25, as shown by a phantom line inFig. 2 . In such case, however, since theoil grooves 26 of the cross shape are provided diametrically at the inlet of thejet 25 to communicate with the inlet of thejet 25 and opened into the piston-lubricatingoil passage 24 in the embodiment, the pressurized lubricating oil within the piston-lubricatingoil passage 24 can be fed under pressure via theoil grooves 26 of the cross shape to thejet 25, as shown by a phantom arrow h inFig. 2 , and can be ejected from thejet 25 toward the back side of thepiston 12. - Although the embodiment of the present invention has been described in detail, it will be understood that the present invention is not limited to the above-described embodiment, and various embodiments may be made within the scope of the invention. For example, although the four
oil grooves 26 are defined in the cross shape diametrically from the center of thejet 25 in the oil passage provided at the inlet of thejet 25 in the above-described embodiment, one to three or five or more oil grooves may be defined diametrically from the center of thejet 25 in place of the four oil grooves. In addition, the lubricating oil passage structure according to the present invention has been described as being carried out in the jet directed to the back side of the piston in the above-described embodiment, but it is of course that the lubricating oil passage structure can be carried out in another jet provided in a lubricating oil passage.
