摘要： 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.

摘要： An ejector includes two or more nozzles arranged in series. A stream of air fed at high velocity through the nozzle is used to create a negative pressure in an outer, surrounding space. The surrounding space is in flow communication with at least one slot located between the nozzles. The nozzles are coupled together and assembled into an integrated nozzle body having at least one flexible valve member integrally arranged within the nozzle body to cover the flow communication with the surrounding space upon reaching a certain, desired pressure difference between the surrounding space and the atmosphere.

摘要： An apparatus for introducing a chemical into a fluid stream comprises a chemical injector adapted to be interposed within the path of the fluid stream flowing from an upstream conduit to a downstream conduit. The chemical injector includes primary and secondary channels, substantially parallel to the fluid flow through the upstream conduit, and a chemical feed channel having an input end, adapted to communicate with a chemical source, and an output end coupled at an angle to the secondary channel. Injection of a chemical into a fluid stream comprises directing the stream through an upstream conduit; dividing the stream into a primary flow and a substantially parallel secondary flow; coupling a chemical source at an angle to the secondary flow; increasing the fluid flow pressure until chemical flow into the secondary flow is induced by vacuum pressure; and directing the primary and secondary flows into the downstream conduit.

摘要： A flow line choke includes a venturi to draw a vacuum in the choke body. This vacuum creates a pressure differential between the producing strata below and the choke body, thereby increasing flow of fluid from the well. A gas recirculation line from the outlet of the choke, through a compressor, back to the choke, provides a source of pressurized gas through a bore in an injector stem to create flow through the venturi.

摘要： A dispenser for dispensing at two flow rates eductively draws a chemical fluid such as a concentrated cleaning solution for diluting with a motive fluid such as water. Using eduction rather than gravity feed provides a consistent dilution ratio over a range of pressures of the motive fluid. A chemical reservoir contains the chemical fluid and a bottle insert assembly for interfacing to the dispenser. The bottle insert assembly seals an opening to the reservoir when the reservoir is not inserted in the dispenser, preventing leaks. Also, the bottle insert assembly includes dual pickup tubes, each with a purge accumulator, to allow dual rate flow at the same or different dilution ratios as well as drawing back unused chemical fluids from the dispenser to avoid carryover or contamination.

摘要： A dispenser selectively mixes one or more chemical fluids into a motive fluid such as water by using diverting motive fluid to one or more channels formed in an eductor body, at least one of the channels being an eductor. When the motive fluid passes through the eductor, a selected chemical fluid is eductively drawn into the venturi of the eductor, producing a mixed fluid having a desired total flow rate and dilution ratio. Additional dilution ratios, flow rates, and chemical fluids are selectable by diverting motive fluid to another channel or combinations of channels. Carry-over of chemical fluid between dispensing is avoided by diverting the motive fluid rather than by diverting the concentrated chemical fluid.
