Abstract
A reciprocating pump is provided with a flexible resilient cylinder which is mounted under tension between two end caps. The end caps are adjustably interconnected by means of a plurality of staybolts whereby the longitudinal tension on the cylinder may be adjusted. A piston comprised of a spherical segment is mounted for reciprocation within the cylinder with the spherical surface of the piston disposed in sliding contact with the cylinder.
