Description
Technical field
The present invention relates to structure for grease channel in the internal-combustion engine of the lubricated part that lubricant oil is supplied to internal-combustion engine.
Background technique
Usually, all be provided with grease channel in the internal-combustion engine, purpose is for the lubricated part supplied with pressurized lubricant oil that grades to the rotation of internal-combustion engine and slide part, turns round swimmingly to guarantee it, in addition, on the suitable position of grease channel, the throttling passage of connection is set, i.e. jetburner, utilize this jetburner to be injected in the pressurized lubrication oil that flows in the grease channel, for example, these lubricant oil that eject are supplied to the inside part of piston, piston is lubricated and cools off.(for example, referring to Japanese kokai publication hei 9-209733 communique)
; though the lubricant oil that flows in grease channel has passed through the filtration of oil purifier; but, still can sneak into impurity such as some metallic dusts or dust unavoidably in these lubricant oil the insides, sometimes; these impurity can arrive on the throttling passage that is arranged on grease channel; be the ingress of jetburner, and stop up inlet, in this case; the oil mass of the lubricant oil that jetburner sprays will occur reducing, perhaps reduce the problem of jet pressure.
Summary of the invention
The present invention proposes in view of above actual conditions, its objective is that the inlet that a kind of jetburner is provided can not stopped up by above-mentioned impurity, the structure of grease channel in the novel internal-combustion engine.
To achieve these goals, the structure of grease channel is in the internal-combustion engine of the present invention, jetburner is located on the appropriate location of the grease channel that links to each other with oil pump, makes the pressurized lubrication oil that flows in grease channel spray to lubricated part by jetburner, it is characterized in that
At the inlet side of above-mentioned jetburner, be provided with and be communicated with this jetburner, from the center of this jetburner to radially extending, and the oil groove that opens wide to above-mentioned grease channel.According to this feature, the ingress that can prevent jetburner is sneaked into impurity such as dust in the lubricant oil, metallic dust and is stopped up, and can pass through frequent injection component of this jetburner and all suitable lubricant oil of pressure.
In addition, on the basis of said structure, also has such feature, promptly, above-mentioned oil groove is to be the center with above-mentioned jetburner, along its cross recess that radially extends, according to this feature, the ingress that can further prevent jetburner is reliably sneaked into and is stopped up in the lubricant oil owing to impurity such as dust, metallic dusts, and can utilize frequent injection component of this jetburner and the suitable lubricant oil of pressure.

Fig. 2 be among Fig. 1 along arrow 2 to view, be the enlarged view of the circle part of imaginary line;
Fig. 3 be among Fig. 2 along arrow 3 to view.
Embodiment
Below, with reference to embodiments of the invention shown in the drawings, embodiments of the present invention are described.
At first, with reference to Fig. 1～3 explanation one embodiment of the present of invention.
In Fig. 1, the body E of quartastroke engine has following each parts: the cylinder block 1 that is provided with cylinder barrel 2; Be fixed on the end face of this cylinder block 1, form the cylinder head 3 of the firing chamber 4 relative with cylinder barrel 2; Be fixed on the crankcase 5 below the cylinder block 1; Be fixed on the oil sump 6 below the crankcase 5.
Usually, the bent axle 7 in the crankcase 5 is bearing on the ball bearing 8, can rotate freely; The big end of connecting rod 10 is connected on the crank pin 7a of this root bent axle 7 by needle bearing 11, can rotate freely; The small end of this connecting rod 10 is connected on the wrist pin 13 of the piston 12 that can be free to slide in cylinder barrel 2, and can freely rotate.
On above-mentioned body E, be provided with the lubrication system L of lubricated its each movable member.The structure of this lubrication system L is known in the past, is connected the lower end of the oil inlet passage 16 on the filler opening of the oil pump 15 on this lubrication system L, is connected with oil purifier 17 in being immersed in the oil sump 6 that stores lubricant oil.In addition, be connected the oil drain passage 18 on the oil drain out of oil pump 15, and on cylinder block 1, form, be communicated with as the main oil gallery 21 of grease channel.
The grease channel 24 that the piston that forms on crankcase 5 is used is communicated with the intermediate portion of main oil gallery 21, jetburner 25 is in the 24a of the wall portion upper shed facing to cylinder barrel 2 of this passage 24, the inlet of this jetburner 25 is communicated with the grease channel 24 that piston is used, in addition, the inside part of the piston 12 of this jetburner in cylinder barrel 2.
As Fig. 2, know in 3 expression, to be provided with the oil groove 26 that is communicated with the inlet side of this jetburner 25 among the present invention in the ingress of above-mentioned jetburner 25.As shown in Figure 3, this oil groove 26 is the center with jetburner 25, radially extend with cross along it, the side that the grease channel of using with piston of this cross oil groove 26 24 is relative is all opened wide on the roughly whole zone of the grease channel 24 that this piston is used.
In addition, label 28 among Fig. 1 is the grease channels that form on bent axle 7, label 29 is and bent axle 7 interlocks, drive the timing transmission device of the valve mechanism work of not representing among the figure, label 30 is to drive the gear that oil pump is used, label 31 is connected on the transmission device, is used to drive the gear of clutch.
This embodiment's effect then, is described.Work as internal combustion engine operation, bent axle 7 rotates, and when driving oil pump 15, behind the lubricant oil that sucks in the oil sumps 6 by oil purifier 17, is pressed and delivered to and forms on cylinder block 1, in the main oil gallery 21 as grease channel.
Flow through the part of the pressurized lubrication oil in the main oil gallery 21, the grease channel 24 that is supplied to piston to use.Then, arrive the lubricant oil of this passage 24, shown in the arrow a among Fig. 1,2, eject, be supplied to the inside part of piston 12 from jetburner 25 towards the inside part of piston 12, lubricated and cool off the inwall of this piston 12 and cylinder barrel 2.
In addition, flow through the lubricant oil of main oil gallery 21, though filtration through oil purifier 17, but, impurity R such as a part of sometimes fine dust and metallic dust are not filtered, will be from the grease channel 24 that main oil gallery 21 inflow pistons are used, these impurity R will the phenomenon of the core of little jetburner 25 inlet sides of obstruction diameter occur shown in imaginary line among Fig. 2.In this case, in the present embodiment, because grease channel 24 1 sides of using to piston are opened wide, the cross oil groove 26 that is disposed radially is connected the inlet side of jetburner 25, so, shown in the imaginary line arrow b among Fig. 2, pressurized lubrication oil in the grease channel 24 that piston is used can be passed through above-mentioned cross oil groove 26, is pressed and delivered to jetburner 25, then, just can spray to the inside part of piston 12.
More than, embodiments of the invention have been described, but the present invention is not limited only to this embodiment, within the scope of the invention various embodiments can be arranged.For example, in the above-described embodiments, on the oil duct of the inlet side that is arranged on jetburner 25, four cross oil grooves 26 to have radially been formed from the center of jetburner 25, but, also can radially form 1～3 from the center of jetburner 25, perhaps 5 with finishing bathtray.In addition, in the above-described embodiments, the structure of grease channel of the present invention has only been illustrated the jetburner that is applied to towards the piston inside part, but self-evident, this structure can be applied to also be arranged on other jetburners on the grease channel.
