Abstract
This invention relates to an all gas-loadable liquid injector. The gas-loadable liquid injector comprises an accumulator for containing a liquid and a propellant gas, a liquid delivery tube for insertion into a material to be treated by the liquid, and intermediate means between the liquid delivery tube and the accumulator. The intermediate means restricts the flow of liquid when the pressure in the accumulator substantially exceeds that in the delivery tube and allows a restricted flow of liquid when the pressure in the accumulator is substantially equal to or less than that in the delivery tube. The intermediate means has a flexible and collapsible tube extending into the accumulator from the bowels of the accumulator and a straight rigid tube having a free end. The free end of the rigid tube always lies at the lowest level in the accumulator regardless of the altitude of the injector so as to dip into any liquid in the accumulator.
