Preliminary filling press mechanism.
Background technology
Pilot needs wearing antigravity suit to improve positive g endurance in flight course, and anti-G valve is the weight of antigravity suit
Part is wanted, the size that it overloads according to air maneuver automatically adjusts the air pressure in anti-lotus capsule in input antigravity suit.
It is advance by anti-G valve preliminary filling press mechanism before the high motor-driven overload of aircraft occurs in order to shorten antigravity suit inflationtime
The air of lower pressure is inputted in anti-lotus capsule into antigravity suit, capsule cavity volume is occupied, after the high motor-driven overload of aircraft occurs,
Input air increase pressure, has been greatly shortened inflationtime, has improved in anti-G valve directly lotus capsule anti-into antigravity suit
The trace performance of anti-G valve.
Current anti-G valve preliminary filling press mechanism is all to be located at vector（± X-direction）On, including it is located at anti-lotus tune
Preacceleration inflation housing on depressor and preliminary filling pressing spring, baffle plate and the valve being located in preacceleration inflation housing, the valve are just resisted
The exhaust outlet of lotus pressure regulator, baffle plate is fixed, and preliminary filling pressing spring is located between baffle plate and valve, in the compression of preliminary filling pressing spring
Gas leakage between the lower valve retention anti-G valve inner chamber piston of effect and pre-punching housing, forms small pressure and completes pre-punching；By
In the limitation of aircraft cockpit space, anti-G valve most constructions are covered by instrument cover plate so that anti-G valve preacceleration inflation
Mechanism installing space is small, and it is in vector（± X-direction）, it is lateral（± Y-direction）, longitudinal direction（± Z-direction）It is difficult to install
Pilot can not conveniently operate after big Operation switch or installation operation switch, so current anti-G valve preliminary filling press mechanism
Do not possess switch selection function（Preliminary filling pressing spring compresses valve all the time, and the pressure release that can not deflate can only be inflated always）, from pilot
Start aircraft engine into cockpit, start to perform aerial mission, until pilot leaves seat after completion task, aircraft landing
Cabin, overall process is inflated to antigravity suit always, although the pressure of pre-punching is low, always to flight in task process is entirely performed
Member's pressurization, can cause pilot uncomfortable, particularly multiple this discomfort of non-stop flight becomes apparent from.
The content of the invention
