It is an application of Hobson’s joint for air compressors. Input: orange shaft. Center of the conrod head moves along an ellipse (in green). Advantages: - Pressure angle on piston is small. - Small crank radius (R) gives large displacement (L) of the piston. L = 2.R.sin(A/2) A: angle between crank rotary axes. Here A = 60 deg., L = 4R Recirculating ball linear bearings for round shaft should be used for the green angular bar. The mechanism has unstable positions when the planes created by axes of two
