Embodiment
The utility model discloses a kind of breather valve, with prevent due to vehicle is rocked, tilts or translated into when fluid enter
Canister.
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belongs to the scope of the utility model protection.
Referring to Fig. 1, the structural representation for the breather valve that Fig. 1 provides for the utility model embodiment.
The utility model discloses a kind of breather valve, including valve body, valve element 1, sliding shoe 2 and fixed block 3.
Offered in valve body in the venthole for offering and being connected with canister on the cavity for accommodating valve element 1, valve body, fuel tank
Oil gas canister is entered by venthole.
In the installation of valve element 1 and cavity, outer wall and the cavity inner wall of valve element 1 form the inlet channel led to for fuel feeding air-flow,
The oil gas entered by the air inlet of valve body enters venthole by inlet channel, then enters canister by venthole.
The lower surface of valve element 1 and the air inlet of breather valve are connected by spring floating, when fuel tank keeps horizontality, bullet
Spring is in compressive state under the Action of Gravity Field of valve element 1, when fuel tank, which is in, to be rocked or even translate into state, and valve element 1 is in itself weight
Moved in the presence of power and spring force towards the upper surface of valve body.
The upper surface of valve element 1, which is provided with, to be provided with the first groove, the first groove and can be moved up and down along the axis of valve body
