Pressure half time is the time required for the peak pressure gradient to reduce by half (1/2) which will correspond to a decrease in peak velocity by a factor of square root of two (21/2). Pressure half time of a regurgitant jet depends on the severity of the regurgitation and the compliance of the receiving chamber.
This is a complicated thing. The high pressure side will measure in excess of 250 psi, but that's not important. When filling 134a, you only need to watch the low pressure side.When the compressor kicks on (which it will only do when the pressure is above 40 psi) the pressure will drop.If the lines are full enough, the pressure will remain around 40-45 psi while it's running.f this happens, (and only if you have 134a) you can release the excess pressure from the valve just like you would emptying a tire. Be sure you do this on the LOW side, and do it while the vehicle is running, so you can watch the pressure.
