Good question. In technical terms it is called an "expression pedal" as in strictest terms the swell pedal controls only the swell division. The same principal applies to all divisions under expression.
Simply put, depressing the expression pedal forward increases the volume. This is called opening the expression pedal. The opposite decreases the volume.
This is accomplished by enclosing the pipes in the division in question in some sort of enclosure and fitting an opening with a set of shades or "shutters." The shades take the form of large Venetian blinds. they are usually made of wood but some builders have used metal and other materials have been used, such as glass on rare occasions.
The enclosure may take the form of a wooden box or a separate room, called an "organ chamber."
The shades may be connected to the shades by direct mechanical linkage or electrically with a motor being used to move the shades.
On a pipe organ the use of the shades is quite different than an electric or electronic organ, such as a Hammond. The expression pedals should not be "pumped" for not only will they will not be able to respond adequately but it will put undue stress and wear on the mechanisms.
Another type of expression pedal also exists. It appears identical to swell type pedals but does not function in the same manner. This is the Crescendo, or Register Crescendo. It works by bringing stops on and off progressively. It is for special effects and should not be used as a means of registration.

Can you build a pipe organ for the chruch?
Yes, building a pipe organ for a church is possible, but it requires specialized knowledge, skills, and resources. The process involves designing the organ to fit the church's acoustics, selecting materials, and constructing the pipes and other components. It's typically best to work with experienced organ builders to ensure the instrument meets both aesthetic and functional needs. Additionally, budget considerations and maintenance plans should be taken into account.
How does a reed work in an organ pipe?
A reed in an organ pipe functions as a sound-producing element by vibrating in response to airflow. When air is blown through a narrow opening, it causes the reed to oscillate, creating pressure variations that generate sound waves. The pitch of the sound is determined by the size and material of the reed, as well as the dimensions of the pipe. This mechanism allows for a rich variety of tones in reed instruments, such as harmoniums and certain types of organs.

What is the value of a Mason Hamlin Liszt pump organ?
I have bought Liszts unrestored from $200 for an oak studio model to $900 for a pipe-top. Restored (to better than new, the kind of work I do) they fetch from $2900 to $3600. But I'm a highly-regarded restorer, and the country's foremost M&H organ expert.

How do you get stripped pedal off of a bike?
If it's an Allen tool interface that has stripped, it's sometimes posible to hammer in a slightly bigger Torx bit and use that instead. Make sure you turn it in the right direction, Left side pedal comes off clockwise. If that doesn't work, remove the pedal platform, then use a vise grip or a pipe wrench to grasp the pedal axle directly to turn it out.
