Abstract
The utility model discloses a piston for a plunger brake master cylinder, which comprises a cylindrical piston body. The annular outer wall of the front end of the piston body is equipped with an annular groove and the piston body is equipped with a plurality of compensation holes arranged corresponding to the annular groove. The diameters of the compensation holes are 1.5-2.5 mm. The piston for a plunger brake master cylinder is simple in structure and the compensation holes of the piston are enlarged. Therefore, a plunger brake master cylinder adopting the piston has the advantages of fast oil supplement, large flow and fast braking response speed.
Description
Technical field:
The utility model relates generally to automobile brake master cylinder technical field, relates in particular to a kind of piston that is used for the plunger type braking overall pump.
Background technique:
In the prior art, be used for having the compensation aperture on the piston of plunger type braking overall pump, diameters of these compensation apertures are 0.7mm mostly.Because the diameter of compensation aperture is less, influenced the repairing speed and the flow of plunger type braking overall pump, the speed of response that causes braking is slow.
The model utility content:
The utility model purpose is exactly in order to remedy the defective of prior art, a kind of piston that is used for the plunger type braking overall pump of reasonable in design to be provided.
The utility model is realized through following technological scheme:
The piston that is used for the plunger type braking overall pump; It is characterized in that: the piston body that includes tubular; The annular outer wall of said piston body front end is provided with annular groove, is positioned at the annular groove section position on the said piston body and is distributed with some compensate openings, and the diameter of said compensate opening is 1.5-2.5mm.
The described piston that is used for the plunger type braking overall pump is characterized in that: the diameter of said compensate opening is 2mm.
The utility model has the advantages that:
The utility model is simple in structure, has enlarged compensate opening, has guaranteed that the repairing of plunger type braking overall pump is fast, and flow is big, has the fast advantage of brake speed of response.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
Embodiment:
Referring to accompanying drawing.
The piston that is used for the plunger type braking overall pump includes the piston body 1 of tubular, and the annular outer wall of said piston body 1 front end is provided with annular groove 2, and being positioned at annular groove 2 site distribution on the said piston body 1 has some compensate openings 3, and the diameter of said compensate opening 3 is 2mm.
