Abstract
The utility model discloses a plunger sleeve which comprises a cylindrical body; two oil holes are arranged on the side wall of the cylindrical body and are communicated with holes in the body; the openings of the two oil holes are opposite, wherein one oil hole is a large-diameter oil hole and the other oil hole is a small-diameter oil hole; the lateral side of the large-diameter oil hole is provided with a threaded hole which forms an included angle of 5-15 degrees with the central line of the large-diameter oil hole; and one side of the threaded hole is communicated with the large-diameter oil hole. As the threaded hole is arranged on the lateral side of the large-diameter oil hole on the plunger sleeve and one side of the threaded hole is communicated with the large-diameter oil hole, the oil volume passing through the oil holes can be adjusted by screwing a bolt into the threaded hole.
Description
Technical field
The utility model relates to a kind of use for diesel engine accessory, particularly relates to a kind of plunger bushing.
Background technique
The oil supply system of diesel engine is referred to as high pressure oil pump, is oil sprayer again.Its power comes from motor itself.The oil suction of Injection Pump and pressure oil are finished by the to-and-fro motion of plunger in plunger bushing.When plunger was positioned at lower position, two oilholes on the plunger bushing were opened, and the oil duct in plunger bushing inner chamber and the pump housing communicates, and fuel oil is filled with the grease chamber rapidly.In case oilhole machines in the existing plunger bushing, the logical oil mass of oilhole is just determined, can not lead to the adjusting of oil mass.
The model utility content
Technical problem to be solved in the utility model just provides a kind of plunger bushing, realizes the adjusting of the logical oil mass of plunger bushing upper oil hole.
For solving the problems of the technologies described above, the utility model adopts following technological scheme: a kind of plunger bushing, comprise the tubular body, described tubular body sidewall is provided with two oilholes and is communicated with the body endoporus, it is characterized in that: described two oilhole apertures are relative, and one of them oilhole is a big footpath oilhole, and another oilhole is the path oilhole, described big footpath oilhole side is provided with one and is the tapped hole at 5 °～15 ° of oblique angles with big footpath oilhole center line, and described tapped hole one side is communicated with oilhole greatly directly.
Preferably, described two oilholes all are the step hole structure, and wherein the oilhole diameter is progressively diminished to the body endoporus by the body outer side wall.
Preferably, the center line of described two oilholes is parallel to each other.
Preferably, described tapped hole center line is 10 ° of oblique angles with the oily centerline hole in big footpath.
The utility model is established a tapped hole by the big footpath oilhole side on plunger bushing, and tapped hole one side is communicated with big footpath oilhole, then by screw in screw in tapped hole, can realize that oilhole leads to the adjusting of oil mass.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is further described:
Fig. 1 is the structural representation of plunger bushing;
Fig. 2 is the structural representation of big footpath oilhole.
Embodiment
As depicted in figs. 1 and 2, embodiment for a kind of plunger bushing of the utility model, comprise tubular body 1, described tubular body sidewall is provided with two oilholes and is communicated with the body endoporus, described two oilhole apertures are relative, one of them oilhole is a big footpath oilhole 2, another oilhole is a path oilhole 3, described big footpath oilhole side is provided with one and is the tapped hole 4 at 5 °～15 ° of oblique angles with big footpath oilhole center line, it all is the step hole structure that described tapped hole one side is communicated with described two oilholes with big footpath oilhole, and wherein the oilhole diameter is progressively diminished to the body endoporus by the body outer side wall.The center line of described two oilholes is parallel to each other.Preferred described tapped hole center line is 10 ° of oblique angles with big footpath oilhole center line.
