The both sides of cover are fixedly connected with the inwall of housing.
The bottom of the valve element is fixedly connected with sprue, and the bottom of the sprue through the top of valve seat and extends to valve seat
Inner chamber.
The present invention can reach following beneficial effect：1st, the present invention can reduce valve by the way that retainer is built in into rotor
Overall height, while solve the problems, such as the reliable stop of retainer, because the first retaining spring extends radially outwardly inferior transverse part, and
Transverse part length can design it is very long, as long as not with rotor inner wall interfere, ensure inferior transverse part have with retainer under elastic track
Sufficient stop surplus, disengagement phenomenon will not be produced, while both at metal, ensure that the stop intensity of abundance.
2nd, the present invention is just stopped at horizontal stroke under locking plate by being provided with upper transverse part at the top of the second retaining spring during stop
In portion, ensure that locking plate has sufficient axial distance with spire on elastic track, prevent that locking plate is axially dry with elastic track
Relate to.
3rd, the present invention on the second retaining spring by being provided with inferior transverse part, and the second retaining spring is in upper stop and operation
During, upper inferior transverse part contacts with locking plate simultaneously, and the first retaining spring stress can reduce the first retaining spring than more uniform
Run noise.
