Abstract
The utility model discloses an oil inlet valve of a brake master cylinder. The oil inlet valve comprises a valve body, a valve leather ring assembled in an inner cavity of a valve body and a valve core assembled in the valve leather ring, where a central boss of the valve leather ring is installed on the lower part of the inner cavity of the valve body; the ring surface of the valve leather ring is tightly combined with the side wall of the cavity opening of the valve body; the central boss of the valve core is installed in a central through hole of the valve leather ring and extends to the upper part of the inner cavity of the valve body; the inner cavity of the valve body is also provided with a valve rod; a spring is connected between the upper end of the valve rod and the top of the inner cavity of the valve body; and a ball head at the lower end of the valve rod butts against a step of a central step through hole of the valve core. The oil inlet valve provided by the utility model is simple in structure, is easy to implement, can improve the response speed of the valve effectively, and improves the oil taking efficiency of the brake master cylinder.
Description
Technical field
The utility model relates to the automobile braking master cylinder field, is specially a kind of braking master cylinder fuel inlet mouth valve.
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.Master brake cylinder comprises cylinder body, is provided with piston in the cylinder body, in the cylinder body oil inlet, is provided with valve.Prior art oil inlet valve mechanism is complicated, poor sealing performance, and valve response is slow, influences braking master cylinder fuel inlet.
The utility model content
The utility model purpose provides a kind of braking master cylinder fuel inlet mouth valve, to solve the slow problem of braking master cylinder fuel inlet mouth valve response in the prior art.
In order to achieve the above object, the technical scheme that the utility model adopted is:
A kind of braking master cylinder fuel inlet mouth valve; Comprise valve body, be assemblied in valve leather circle in the body cavity, be assemblied in the spool in the valve leather circle with inner chamber; It is characterized in that: said body cavity bottom is straight chamber, and body cavity top is conical cavity, and said valve leather circle has central boss and the central through hole that runs through the valve leather circle; The central boss of said valve leather circle is installed in the body cavity bottom; And valve leather circle circle face and valve body accent sidewall are combined closely, and said spool has central boss and the center step through-hole that runs through spool, and the central boss of spool is installed in the valve leather circle central through hole and passes valve leather circle central through hole and stretch into body cavity top; Also be provided with the valve rod that the lower end is a bulb in the said body cavity; Be connected with spring between said valve rod upper end and the body cavity top sidewall, said spool is enclosed within outside the valve rod through the center step through-hole, and valve rod lower end bulb is replaced at center spool step through-hole step place.
The utility model is simple in structure, is easy to realize.Valve body, valve leather circle, spool are assembled into one; And combine closely each other; The valve rod upper end is connected with body cavity top sidewall through spring; Center spool step through-hole step place is stopped up through bulb in the valve rod lower end, can effectively improve the speed of response of valve through the elastic response of spring, has improved braking master cylinder fuel inlet efficient.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
As shown in Figure 1.A kind of braking master cylinder fuel inlet mouth valve; Comprise valve body 1, be assemblied in valve leather circle 2 in valve body 1 inner chamber, be assemblied in the spool 3 in the valve leather circle 2 with inner chamber; Valve body 1 inner chamber bottom is straight chamber, and valve body 1 inner chamber top is conical cavity, and valve leather circle 2 has central boss 4 and the central through hole that runs through valve leather circle 2; The central boss 4 of valve leather circle 2 is installed in valve body 1 inner chamber bottom; And valve leather circle 2 circle faces and valve body 1 accent sidewall are combined closely, and spool 3 has central boss 5 and the center step through-hole that runs through spool 3, and the central boss 5 of spool 3 is installed in valve leather circle 2 central through holes and passes valve leather circle 2 central through holes and stretch into valve body 1 inner chamber top; Also being provided with the lower end in valve body 1 inner chamber is the valve rod 7 of bulb 6; Be connected with spring 8 between valve rod 7 upper ends and the valve body 1 inner chamber top sidewall, spool 3 is enclosed within outside the valve rod 7 through the center step through-hole, and valve rod 7 lower end bulbs 6 are replaced at step through-hole step place, spool 3 center.
