Patent number: 9175725Abstract: A rocking journal bearing for a two-stroke cycle engine includes a bearing sleeve having a bearing surface with a plurality of axially-spaced, eccentrically-disposed surface segments and a rocking journal having a plurality of axially-spaced, eccentrically-disposed journal segments. The rocking journal is retained for rocking oscillation on the bearing surface. Space for receiving oil is provided in the rocking journal and oil delivery outlets acting through the journal segments deliver received oil to the bearing surfaces.Type: GrantFiled: February 25, 2013Date of Patent: November 3, 2015Assignee: ACHATES POWER, INC.Inventors: Eric P.

Patent number: 9163505Abstract: A piston construction for an opposed-piston engine accommodates contoured end surfaces of the piston crowns and articulation of the pistons with piston rods. The shape of each piston crown includes a bowl with an adjoining ridge that protrudes axially of the piston. A cooling construction for the piston includes an outer gallery running around the inner surface of the piston sidewall in the vicinity of the crown. The outer gallery girds and is in fluid communication with a central gallery that abuts the deepest part of the bowl. The outer gallery has an asymmetric profile that rises under the ridge and that slants upwardly under a peripheral portion of the bowl. A mechanism for coupling the piston to a piston rod includes a biaxial slipper bearing.Type: GrantFiled: August 15, 2011Date of Patent: October 20, 2015Assignee: ACHATES POWER, INC.Inventors: Eric P. Dion, Brendan M. Lenski, Ryan G. MacKenzie

Patent number: 8539918Abstract: Integrated, multi-cylinder opposed engine constructions include a unitary support structure to which cylinder liners are removeably mounted and sealed and on which crankshafts are rotatably supported. The unitary support structure includes cooling manifolds that provide liquid coolant to the cylinder liners. Exhaust and intake manifolds attached to the support structure to serve respective ports in the cylinder liner. The engine constructions may also include certain improvements in the construction of cooled pistons with flexible skirts, and in the construction of cylinders with sealing structures mounted outside of exhaust and inlet ports to control lubricant in the cylindrical interstice between the through bore and the pistons.Type: GrantFiled: February 12, 2010Date of Patent: September 24, 2013Assignee: Achates Power, Inc.Inventors: James U.
