Abstract
The utility model relates to a car clutch booster pump control valve, which belongs to the field of the car accessory, and aims at providing a car clutch booster pump control valve through improving the original structure, and comprises a U-shaped gasket ring and a piston mandril, wherein the O-shaped gasket ring is arranged on the piston mandril, and an air valve is of a sealing gasproof structure. The control valve is improved, so that the structure of the booster pump is more reasonable, and the performance is more reliable.
Description
Technical field:
The utility model belongs to the auto parts machinery field.
Background technique:
Because it is heavy that pedal often appears in the heavy goods vehicles control system, the fault mode that the not thorough friction plate of clutch separation is ablated, wherein cause the friction plate ablation for user's overload except that a part, basic reason is that gas leak of the oil leakage caused boost pump to lose efficacy after there was sealing part abrasion in the boost pump original structure, thereby causes the clutch rate of fault high.
Summary of the invention:
The purpose of this utility model is by original structure is improved, thus the automobile clutch boost pump control valve that addresses the above problem.
The utility model comprises U-shaped seal ring, piston mandril, and O-ring seals is installed on piston mandril, and air valve is the sealed air-tight structure.
The utility model core control valve improves, and makes the power-assisted pump structure more reasonable, and performance is more reliable.First: piston mandril increases to two seals by the sealing together of original structure, and second changes the venting gas circuit moves towards the cancellation seal ring, thoroughly avoids causing boost pump gas leakage behind the ring wear.
Description of drawings:
Accompanying drawing is the utility model structure sectional view.
Embodiment:
The utility model comprises U-shaped seal ring 3, piston mandril 1, and U-shaped seal ring 3 itself plays seal action to piston mandril 1, and an O-ring seals 2 has been installed on piston mandril 1 now, thereby reinforces sealing effect.Original air valve 4 centers are hollow, and seal ring is installed in the end, air communication is crossed the central hollow of the hollow and piston mandril 1 of air valve and is discharged, and seal ring prevents gas leakage, existing air valve 4 is the sealed air-tight structure, air-flow does not pass through air valve 4, is only discharged by the center of piston mandril 1.
Claims (1)
1, a kind of automobile clutch boost pump control valve comprises U-shaped seal ring (3), piston mandril (1), it is characterized in that: O-ring seals (2) is installed on piston mandril (1), and air valve (4) is the sealed air-tight structure.
