Abstract: 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.

Abstract: A venturi type pumping device including a body having a tubular through bore between a bore inlet end and a bore outlet end, a restriction in the bore acting to produce a reduction in pressure downstream from the restriction, a delivery device for the delivery from a delivery outlet of a pressurized stream of liquid substantially axially aligned with the bore and upstream from the bore inlet end, a bore extension member which terminates upstream from and encloses the delivery outlet, and a mounting device provided on the body for sealing engagement of the bore extension member to the body.

Abstract: An air pump (10) having a separation chamber (15) defined by a top wall (11), a bottom wall (12) and generally annular side walls (13). A liquid entry tube (24) configured to draw air into a stream of liquid passing through the liquid entry tube is coupled to the separation chamber so that the air/liquid mixtures rotates within the separation chamber. The rotation of the mixture causes air to accumulate within a central zone (30) and the liquid to accumulate about a peripheral zone (31). The continued flow of the mixture causes the accumulating air to become pressurized where it is released through an air exit tube (20) in fluid communication with the central zone of the separation chamber. The liquid is expelled through a liquid exit port (18).

Abstract: An improved vacuum apparatus and method is provided which includes a vacuum body, pump or ejector which produces a plurality of high velocity liquid jet streams of a primary fluid (liquid) such as water discharged into a convergent diffuser to draw a secondary fluid (gas) such as air into a vacuum chamber. The secondary fluid (gas) is entrained within flow spaces formed between the liquid jet streams and is carried through the diffuser by the jet streams. A secondary fluid inlet is operatively connected to an elongate hose which serves as a vacuum line for evacuating, for example, a Mason Jar, a plastic bag, other food storage container, an oil storage or receiving receptacle, or the like. The present invention is especially adapted for use as or in a vacuum seal kit or oil change kit, but not limited thereto.

Abstract: In an aspirator (10) for pumping air into an inflatable (16), initial delivery of an aspirating fluid extends a piston (68) and the piston (68) extends an aspirator tube (24) to open an ambient air inlet (30) and render the aspirator (10) operable. Aspirating fluid pressure acts on a valve plug (112) and moves it into a first position in which the aspirating fluid pressure is connected to the linear fluid motor (66) for extending the piston (68). When inflation is substantially completed, back pressure from the inflatable (16) acts on a movable wall (74) which is connected to the valve plug (112) to produce a force which overrides the force of the aspirating fluid pressure acting on the valve plug (112). The overriding force moves the valve plug (112) into a second position in which flow of aspirating fluid into the linear motor (66) is blocked and the piston (68) is vented. A spring (48) then retracts the aspirator tube (24 ) closing the ambient air inlet (30), and disabling the aspirator (10).

Abstract: A device for use as a convenient, easy-to-use, and inexpensive pump for pumping water is disclosed which uses water pressure from a standard garden hose connected from a tap to the pump apparatus as the motive power to pump between seven and eleven times the volume of the water from the garden hose from a reservoir into a discharge hose which is any of several different standard sizes and which is connected to the pump apparatus. The water from the garden hose flows into the pump through a pump inlet having a reduced diameter venturi, which increases the velocity of the water, into a pumping chamber with the resulting drop in pressure creating a vacuum in the pumping chamber. The vacuum in the pressure chamber draws water from a reservoir the pump is placed in through a reservoir inlet chamber into the pumping chamber in the pump body, and the water exits the pumping chamber through a pump outlet located on the opposite side of the pumping chamber from the pump inlet.

A valve with predetermined controls the degree or ratio of concentrate.

Abstract: Portable, self-powered water pumping apparatus for use in sampling water in remotely located wells comprises a wheeled hose reel cart which supports a long length of co-extruded plastic hose or tubing. The co-extrusion comprises a small diameter portion of tubing attached by a web to a large diameter portion of tubing. The smaller diameter tubing is connected to a pressurized cylinder of gas such as a standard 14 oz. propane gas cylinder. A generally J-shaped piece of metal tubing projects from the inside of the smaller tubing, which it frictionally engages, into the center of the larger tubing at the lower end thereof. When the lower ends of the tubes are well submerged beneath the water level in a well, admission of gas to the smaller tube at its upper end will force water which enters the larger tubing in the annular space surrounding the metal tubing up through the larger tube and out the upper end of the larger tube so that it can be collected.
