Abstract
A flow path for the pressure gas which is to be connected to a pressure gas feeder is formed almost rectilinearly, a liquid reservoir chamber to be connected to a pressure liquid feeder is provided in the flow path for the pressure gas. The sectional area of the flow path for the pressure fluid is gradually reduced to form an accelerating portion, an injection port for a liquid injection nozzle communicating with the liquid reservoir chamber is provided in the acceleration portion and a gas injection port is formed on the outside to enclose the injection port of the liquid injection nozzle. A powder and granular material may be mixed into the pressure gas or the pressure liquid, or a detergent may be added into the pressure liquid.
Claims10
An injection apparatus for a gas-liquid mixed flow which mixes and injects at least a pressure gas and a pressure liquid, comprising:
- a flow path formed within an elongated apparatus body for the pressure gas to be connected to a pressure gas feeder and being formed almost rectilinearly;
- a liquid reservoir being provided in said flow path for the pressure gas, and to be connected to a pressure liquid feeder;
- an accelerating portion which is formed by gradually reducing a sectional area of said flow path for the pressure gas;
