A piston system including a body defining a bore and a piston positioned inside the bore and mounted for reciprocation therein. The piston includes a crown and a skirt extending generally away from the crown, the skirt including a pair of opposed panel portions. The piston further includes a transition portion configured to first engage the body during reciprocation of the piston in the bore. The piston is configured such that additional movement of the piston in the bore after the first engagement causes additional contact between the piston and the body, the additional contact increasing or moving in a circumferential direction about the piston. The piston is configured such that maximum side loading forces from the body to the piston are applied to the piston at one of the panel portions. |
