How does the liquid inside an aerosol can come out through the nozzle when it is depressed to spray?

In an aerosol can a gas is filled under a very high
pressure. Due to the high pressure a part of the gas is converted to a liquid. When the
button of the aerosol can is depressed, there is an opening created and the pressurized
gas inside the can is expelled out of it. As this reduces the level of the pressure
inside, a part of the liquid is converted to gas till the equilibrium is
attained.

There is no relation between the gases above the
liquid inside the aerosol can helping the liquid to come out. The whole process is due
to the highly pressurized gas filled inside.
