The design of oil storage kettle mouth, consider and the gap of all edge pieces and the clamping space of vacuum filling braking liquid equipment, in most cases oil storage kettle mouth is designed to there is certain angle of inclination with vertical direction, angle a as shown in Figure 1.Due to the existence at oil storage kettle mouth angle of inclination, automobile is when long and steep downgrade braking or emergency braking, and the braking liquid in oil storage kettle can flow to oil storage kettle surface by air passage, easily causes user to complain.Therefore, oil storage kettle can not be caused again while how ensureing oil storage kettle permeability to air to reveal, become a difficult problem for various equivalent modifications tackling key problem.
Summary of the invention
The purpose of this utility model is to provide a kind of automobile brake oil storage kettle cap assembly, the ventilation of automobile brake oil storage kettle, dust-proof requirement can not only be met, can also effectively prevent braking liquid from leaking into oil storage kettle surface by venting channels, and structure is simple, cost is low, is easy to realize.
A kind of automobile brake oil storage kettle cap assembly described in the utility model, comprises oil storage pot lid and the ventilation valve body of top rotary clamping in oil storage pot lid, is provided with seal ring in the middle part of described ventilation valve body, and middle part and the bottom of ventilation valve body are stretched in oil storage kettle; Described ventilation valve body central upper portion position is provided with the oil resevoir of a circle, be provided with in described oil resevoir about one symmetrical and opening back to bowl-shape seal cap, the outer wall of described seal cap coordinates with oil resevoir inwall.
Further, be provided with the first vent on the top of described seal cap, bottom is provided with the second vent; Bottom the oil resevoir of described ventilation valve body, be provided with air extractor vent by paracentral position, be provided with fan-shaped air passage in the bottom of described ventilation valve body; The middle part of described ventilation valve body and bottom and oil storage kettle mouth inner wall free-running fit, form the louver of a ring-type, described louver communicates with the inner chamber of oil storage kettle downwards, upwards communicates with described oil resevoir through air passage, air extractor vent, the second vent and the first vent successively.
Further, described seal cap adopts elastomeric material to make.
Further, the height of described seal cap is less than or equal to the degree of depth of oil resevoir.
Further, the outer wall of described seal cap and the inwall interference fit of oil resevoir.
The utility model by arranging a seal cap in the oil resevoir of the central upper portion of ventilation valve body, and arranges vent in seal cap upper and lower end parts, not only ensures the aeration of oil storage kettle cap assembly, and prevents braking liquid from leaking into oil storage kettle surface when braking.The utility model has structure advantage simple, reasonable in design, with low cost.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
See a kind of automobile brake oil storage kettle cap assembly shown in Fig. 2 to Fig. 5, comprise oil storage pot lid 1 and the ventilation valve body 2 of top rotary clamping in oil storage pot lid 1, a little up and down amount is had between described oil storage pot lid 1 and ventilation valve body 2, be provided with seal ring 3 in the middle part of described ventilation valve body 2, middle part and the bottom of ventilation valve body 2 are stretched in oil storage kettle 4; Described ventilation valve body 2 central upper portion position is provided with the oil resevoir 2.2 of a circle, be provided with in described oil resevoir 2.2 about one symmetrical and opening back to bowl-shape seal cap 5, the outer wall of described seal cap 5 coordinates with oil resevoir 2.2 inwall.
Further, be provided with the first vent 5.1 on the top of described seal cap 5, bottom is provided with the second vent 5.2; Bottom the oil resevoir 2.2 of described ventilation valve body 2, be provided with air extractor vent 2.3 by paracentral position, be provided with fan-shaped air passage 2.4 in the bottom of described ventilation valve body 2; The middle part of described ventilation valve body 2 and bottom and oil storage kettle 4 mouth inner wall free-running fit, form the louver 2.5 of a ring-type, described louver 2.5 communicates with the inner chamber of oil storage kettle 4 downwards, upwards communicate with described oil resevoir 2.2 through air passage 2.4, air extractor vent 2.3, second vent 5.2 and the first vent 5.1 successively, ensure the aeration of oil storage kettle cap assembly.
