This utility model has the beneficial effects that: the deformation of spring(-supported) mount when this utility model reduces electromotor operating, reduction is many
The degree-of-difficulty factor that individual biasing spring is taken a seat simultaneously, optimizes pivot angle during biasing spring work, and the resisting fatigue improving biasing spring is strong
Degree.Specially 1) top of each swing arm unit group is equipped with biasing spring seat, biasing spring and biasing spring frame composition
Biasing spring frame assembly, i.e. every cylinder all has a biasing spring frame, so, reduces length and the deflection of biasing spring frame,
Add the rigidity of biasing spring frame, reduce the assembly difficulty simultaneously taken a seat by many biasing springs；2) set on exhaust rocker arm
Having the first biasing spring seat slot, brake rocker arm is provided with the second biasing spring seat slot, during installation, it is only necessary to ensure that 2 springs enter
In biasing spring seat slot on rocking arm, easy installation and reliable, spring steadiness is good；3) by design spring(-supported) mount support and increase
Solenoid valve seat supports the function of spring, have adjusted the setting angle of spring(-supported) mount, makes pendulum angle during spring works more reasonable,
Improve the endurance life of spring.
