Abstract
The utility model discloses a valve seat for a brake main cylinder. The valve seat includes a seat body, the lower part of the step through cavity of the seat body is provided with a valve rubber ring, a valve core is arranged in the valve rubber ring, a circlip is arranged at the cavity opening at the lower part of the seat body, and a spring is connected between the valve rubber ring and the circlip. The valve seat, which is simple in structure and easy in realization, can effectively improve the resetting speed of the valve core of the valve seat of the brake main cylinder, and can further improve the oil liquid transmission efficiency of the brake main cylinder.
Description
Technical field
The utility model relates to the automobile braking master cylinder field, is specially a kind of master brake cylinder and uses valve seat.
Background technology
Automobile braking master cylinder is the vitals in the brake system of car, and its effect is that the piston through master brake cylinder pushes fluid in the brake cylinder, to realize the braking brake in the running.Be provided with piston in the master brake cylinder, in the piston termination valve seat be installed in the master brake cylinder that has.When the prior art valve seat was realized the fluid transmission at fitting piston, valve seat inner spool reset speed was slow, influences master brake cylinder fluid transmission efficiency.
The utility model content
The utility model purpose provides a kind of master brake cylinder and uses valve seat, influences the problem of master brake cylinder fluid transmission efficiency slowly with the valve core reset speed that solves master brake cylinder valve seat in the prior art.
In order to achieve the above object, the technical scheme that the utility model adopted is:
A kind of master brake cylinder is used valve seat; Include pedestal, the step cavity is arranged in the said pedestal, the pedestal external wall of upper portion forms circular groove; It is characterized in that: the step cavity bottom of said pedestal is slidingly fitted with the valve leather circle; The spool that passes pedestal step cavity step place and stretch into pedestal step cavity top is installed in the said valve leather circle, and accent place, said pedestal bottom is fixed with circlip, is connected with spring between said valve leather circle and the circlip.
Described a kind of master brake cylinder is used valve seat, it is characterized in that: be provided with seal ring in the circular groove of said pedestal.
The utility model is simple in structure, is easy to realize.As external bracing, valve seat accent place is provided with circlip to valve seat by pedestal, and the valve leather circle that is slidingly installed in the valve seat, spool are fixed on the valve leather circle, realizes in time resetting of spool through the spring between circlip and the valve leather circle.The utility model can improve valve core reset speed in the brake master cylinder piston valve seat effectively, and then has improved master brake cylinder fluid transmission efficiency.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
As shown in Figure 1.A kind of master brake cylinder is used valve seat; Include pedestal 1, the step cavity is arranged in the pedestal 1, pedestal 1 external wall of upper portion forms circular groove; The step cavity bottom of pedestal 1 is slidingly fitted with valve leather circle 2; The spool 3 that passes pedestal 1 step cavity step place and stretch into pedestal 1 step cavity top is installed in the valve leather circle 2, and accent place, pedestal 1 bottom is fixed with circlip 4, is connected with spring 5 between valve leather circle 2 and the circlip 4.Be provided with seal ring 6 in the circular groove of pedestal 1.
