Calculation of Piston Side Loads on Sanderson Pumps and Compressors (pdf)
Albert E. Sanderson, Ph.D.
The piston side load of the Sanderson Mechanism has been under discussion recently, and some engineers have been questioning whether our piston joint, called the "zero side load" (ZSL) joint, really is literally zero as claimed. This paper is intended to show that to be actually the case, based on the geometry of the ZSL joint.
