Volume Variations
In beta and gamma engines, generally the phase angle difference between the piston motions is not the same as the phase angle of the volume variations. However, in the alpha Stirling, they are the same. The rest of the article assumes sinusoidal volume variations, as in an alpha Stirling with co-linear pistons, so named an "opposed piston" alpha device.

Famous quotes containing the words volume and/or variations:
“The other 1000 are principally the ‘old Yankee stock,’ who have lost the town, politically, to the Portuguese; who deplore the influx of the ‘off-Cape furriners’; and to whom a volume of genealogy is a piece of escape literature.”
—For the State of Massachusetts, U.S. public relief program (1935-1943)
“I may be able to spot arrowheads on the desert but a refrigerator is a jungle in which I am easily lost. My wife, however, will unerringly point out that the cheese or the leftover roast is hiding right in front of my eyes. Hundreds of such experiences convince me that men and women often inhabit quite different visual worlds. These are differences which cannot be attributed to variations in visual acuity. Man and women simply have learned to use their eyes in very different ways.”
—Edward T. Hall (b. 1914)
