The Air Pumps ClipArt gallery provides 18 illustrations of pumps designed to move air for a variety of industrial and scientific purposes.

"The air pump is an instrument for removing air from a given space. A closed vessel R is called the receiver, and the space that it encloses is that from which it is desired to remove the air. It is usually made of glass, and the edges are ground so as to be perfectly air-tight. When made in the form shown, it is called a bell-jar receiver." — Hallock, 1905

"The air pump is an engine by which the air can be pumped out of a vessel, or withdrawn from it. The vessel so exhausted, is called a receive, and the space thus left in the vessel, after withdrawing the air, is called a vacuum. The principles on which the air pump is constructed are readily understood, and are the same in all instruments of this kind, though the form of the instrument itself is often considerably modified. Let R be a glass vessel, or receiver, closed at the top, and open at the bottom, standing on a perfectly smooth surface, which is called the plate of the air pump. Through thie plate is an aperture, which communicates with the inside of the receiver, and the barrel of the pump. The piston rod works air tight through the barrel. At the extremity of the barrel, there is a valve which opens upwards, and is closed as the piston rises." —Comstock, 1850

"The piston rods are furnished with racks, or teeth, and are worked by the toothed wheel a, which is turned backwards and forwards, by the lever and handle b. The exhaustion pipe c, leads to the plate on which the receiver stants. The valves v, n, u, and m, all open upwards." —Comstock, 1850

A pump is a device used to move fluids, such as liquids or slurries, or gases. A pump displaces a volume by physical or mechanical action. One common misconception about pumps is the thought that they create pressure. Pumps alone do not create pressure; they only displace fluid, causing a flow. Adding resistance to flow causes pressure. Pumps fall into five major groups: direct lift, displacement, velocity, buoyancy and gravity pumps, and their names describe the method for moving a fluid.

"A form of air-engine which was invented in 1816 by the Rev. R. Stirling is of special interest as embodying the earliest application of what is known as the "regenerative" principle, the principle namely that heat may be deposited by a substance at one stage of its action and taken up again at another stage but with little loss, and with a great resulting change in the substance's temperature at each of the two stages in the operation." —Encyclopedia Britannica, 1910

"Hearson's machine is cylindrical in form, and is surmounted by two turrets. Internally the cylinder is divided into two compartments by a transverse portion, one being occupied by a rotary blower, an apparatus similar in construction to the drum of a water-meter, and the other by an elevator or dipper wheel, the function of which is to raise gasolin into the blower chamber, where the gasoline must be maintained at a constant level." — Encyclopedia Britannica, 1893

"An American machine, introduced into England by Mr. Ellis. It consists of an iron cylindrical casing A, open about a fourth part of its circumference (a to b) for admission of air, and an exit pipe B. Inside the casing is another cylinder, placed eccentrically to it, and which always fits close up against the wooden packing C. This cylinder acts as a driver for the three fan blades or pistons D, which are capable of passing out and in through longitudinal slits in its circumference. There is a shaft passing through the small cylinder, and concentric with it at the ends, but cranked in the middle part so as to become concentric with the casing. The inner cylinder revolves round the axis of the ends of the shaft, and on the cranked part revolve the fan blades or pistons, driven by the cylinder." — Encyclopedia Britanica, 1893
