The device comprises a valve and a piston arranged inside the valve and is characterized in that a nozzle shell is sleeved on the valve; a gap is reserved between the nozzle shell and the valve to form a sealed high pressure oil chamber; an oil spray hole is formed on the nozzle shell and communicated with the high pressure oil chamber; an oil hole is formed on the valve; and the high pressure oil chamber is communicated with an oil cylinder inside the valve via the oil hole formed on the valve. The device for lubricating the chains of the motors has the advantages that the nozzle shell is arranged above a hole formed on an oil passage of a cylinder cover for performing lubrication to transmission system of the chains and the nozzle shell adopts the structure of a one-way valve for controlling flow rate of the lubricating oil by using oil pressure, so as to achieve accurate control to the flow rate of the lubricating oil and ensure low probability of leakage of the lubricating oil.
Description
Technical field
The utility model relates to a kind of lubricating fitting, relates in particular to a kind of flow of lubrication precise control, the antileakaging engine chain lubricating fitting of lubricant oil.
Background technique
The lubricated mode of traditional motor chain drive system is generally: oilhole of a processing or fine steel tube oil nozzle is installed on cylinder cap chain drive system is lubricated on cylinder body, cylinder cap, but this mode flow of lubrication control is inaccurate, and when system shut down, lubricant oil can leak along oil duct.China's utility model patent 95211378.3 discloses a kind of chain lubrication assembly, it is by oil conservator, valve and oil guide pipe are formed, valve is positioned at the lower end of oil conservator, the below of valve connects the upper end of oil guide pipe, in addition, lubricating fitting also has Oil Guide parts, be positioned at the oil guide pipe below, be made up of Oil Guide seat and hairbrush, wherein the Oil Guide seat is provided with through hole and passes by oil guide pipe, makes the following top that is positioned at hairbrush that corrects of oil guide pipe, have through hole on the matrix of hairbrush, can allow lubricant oil in oil guide pipe flows into hairbrush, hairbrush is contacted with chain, the hairbrush that is filled oil can spread upon oil on the chain of motion equably.Come lubricated effect though this device plays, control is inaccurate this device to flow rate of lubricating oil, and this device has also adopted a kind of electromagnetic valve, controls lubricant oil by the degree of saturation of induction oil-containing, but this apparatus structure complexity, cost is also higher.
Summary of the invention
It is inaccurate to flow of lubrication control that the utility model has mainly solved general chain lubrication assembly, and the problem that lubricant oil leaks easily provides a kind of to flow of lubrication precise control and the antileakaging engine chain lubricating fitting of lubricant oil.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of engine chain lubricating fitting, comprise valve body, in valve body, be provided with piston, on valve body, be with nozzle body, leave the high-voltage oil cavity that the space forms a sealing between described nozzle body and valve body, be provided with nozzle opening on nozzle body, described nozzle opening is connected with high-voltage oil cavity, be provided with the valve body oilhole on valve body, high-voltage oil cavity is connected with the valve body inner cylinder by the valve body oilhole.Valve body in the utility model adopts the one-way valve form, by oil pressure control flow rate of lubricating oil, when chain transmission is fast, oil pressure increases, and then valve body is opened, and when chain transmission is slow, then do not need chain is lubricated, more accurate to flow of lubrication control, also saved lubricant oil simultaneously.When engine stoping operation, because the existence of valve body, lubricant oil can not leak.
As a kind of preferred version of such scheme, described nozzle body seals with valve body at two ends up and down mutually.Make the lubricant oil of high-voltage oil cavity can not let out.
As a kind of preferred version of such scheme, between piston rear end and valve body bottom, be provided with spring.This spring makes piston that a downward active force be arranged, can be so that piston moves up and down, when oil pressure is big according to lubricant oil oil pressure size, move on the piston, high-voltage oil cavity is connected with the oil cylinder of valve body, and lubricant oil enters high-voltage oil cavity, by nozzle opening chain is lubricated.
As a kind of preferred version of such scheme, for holding the through hole of piston, this through hole is beloid in the middle of the described valve body, and the intersection, front and rear part forms a transition part, and described piston nose overhead is on transition part, and described valve body oilhole is arranged on the transition part top.Piston is contained in the wide end of through hole, and the valve body oilhole is arranged on the transition part top, when then piston moves up, high-voltage oil cavity is connected with the oil cylinder of valve body.
The utility model has the advantages that: chain drive system is lubricated by a chain nozzle body is installed on the cylinder cap oil channel hole, this chain nozzle body adopts one-way valve structures, by oil pressure control flow rate of lubricating oil, to the flow of lubrication precise control, also make that lubricant oil is difficult for leaking simultaneously.
Description of drawings
Fig. 1 is a kind of sectional structure schematic representation of the present utility model.
Embodiment:
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is further described.
Embodiment:
A kind of engine chain lubricating fitting of present embodiment, as shown in Figure 1, comprise valve body 1, be provided with the through hole 7 that holds piston 2 in the middle of this valve body, this through hole is beloid, the intersection, front and rear part forms a transition part 8, and the piston nose overhead is provided with spring 3 between piston rear end and valve body bottom on transition part.Outer cover at valve body is equipped with nozzle body 4, this nozzle body links to each other with valve seal at two ends up and down, leave the space between part between the two ends and the valve body up and down, form the high-voltage oil cavity 9 of sealing, on the transition part top position of valve body 1, be provided with valve body oilhole 5, valve body oilhole and high-voltage oil cavity are conducted, and when piston was moved upward to valve body oilhole place, this valve body oilhole made high-voltage oil cavity and valve body oil cylinder 11 be conducted.Be provided with nozzle opening 10 on nozzle body 4, this nozzle opening is connected with high-voltage oil cavity.
During work, set up back lubricant oil at oil pressure and promote piston 2 pressure springs 3 along valve body 1, piston moves up.When piston moved to valve body oilhole 5 positions, lubricant oil entered the high-voltage oil cavity 9 of valve body 1 with 4 of nozzle bodies, and lubricant oil is ejected on the chain along the nozzle opening on the nozzle body 4 10, reached the purpose of lubricated chain drive system.When system shut down, spring 3 pressure were greater than engine oil pressure, promoted piston 2 and moved down closed valve 1 and oil circuit, lubricant oil is stored in the oil circuit and does not reveal, and can set up oil pressure fast during next start-up system.
