the pressure and temp. are not available at these point but I think that when the coil is completely full with pumped liquid the gas resulting from evaporation and goes up against the liquid hole happening decrease in ΔP. this make liquid stop and when the ΔP increase again liquid flow will start again IS MY THINKING OK OR NO ?
