High Pressure Spherical Piston.

Abstract

A high pressure spherical piston, which can also be thought of as a spherical piston with a very small diametrical clearance, is created by moving an o-ring to a nonsymetrical position. Shifting the o-ring to one side of the piston permits the spherical piston to have a diameter less than the diameter of the cylinder walls without the normal loss of pressure. Lubrication of the piston prevents o-ring extrusion. The placement of the o-ring limits the piston to a single acting mode. (Author)
