Patent number: 8807112Abstract: A piston rolling thrust bearing construction is constituted of a pair of bearing plates with opposing faces disposed in a spaced alignment with a rolling ball assembly positioned between the opposing faces to support relative movement between the bearing plates. The piston rolling thrust bearing is mounted to the open end of the skirt of a piston disposed in a cylinder to compensate for non-axial motion relative to the cylinder axis due to the articulating motions of connecting elements or any structural misalignments within an engine drive train assembly.Type: GrantFiled: February 2, 2011Date of Patent: August 19, 2014Assignee: Achates Power, Inc.Inventors: James U. Lemke, Patrick R. Lee, William B. McHargue, Bryant A. Wagner

Patent number: 8286596Abstract: In a two-cycle, opposed-piston internal combustion engine, opposed pistons disposed in a cylinder are coupled to a pair of side-mounted crankshafts by connecting rods that are subject to substantially tensile forces acting between the pistons and the crankshafts. This geometry reduces or eliminates side forces between the pistons and the bore of the cylinder. The cylinder and the pistons are independently cooled to reduce cylindrical deformation caused by thermal expansion during engine operation.Type: GrantFiled: December 8, 2011Date of Patent: October 16, 2012Assignee: Achates Power, Inc.Inventors: James U. Lemke, William B. McHargue, Michael H. Wahl, Patrick R. Lee

Patent number: 8281755Abstract: An internal combustion engine including a cylinder with bore and a piston disposed to reciprocate in the bore is operated by moving the piston in the bore between top and bottom dead center positions and applying lubricant to a portion of the piston that protrudes from the bore. Lubricant is wiped from the piston as the piston travels into the bore toward its top dead center position.Type: GrantFiled: March 12, 2008Date of Patent: October 9, 2012Assignee: Achates Power, Inc.Inventors: James U. Lemke, William B. McHargue

Publication number: 20110186017Abstract: Ported engines with opposed pistons are coupled to a single crankshaft through rocker arm linkages. Each pair of opposed pistons is coupled to a single crankpin of the crankshaft. Each piston is coupled to a respective rocker arm linkage by a rolling thrust bearing which prevents linkage movement that is transverse to the axis of the piston from being transferred to the piston. Each piston of a pair of opposed pistons is coupled to the same crankpin by respective rocker arm linkages in which connecting rods run between the crankpin and respective rocker arms. One connecting rod is connected to first rocker arm below the rocker arm's pivot point and another connecting rod is connected to a second rocker arm above the rocker arm's pivot point.Type: ApplicationFiled: February 2, 2011Publication date: August 4, 2011Applicant: Achates Power, Inc.Inventors: James U.

Patent number: 7931005Abstract: An electrical generator includes an opposed piston, internal-combustion engine with a piston and a hypocycloidal drive connected by a rod to the piston. The construction of the hypocycloidal drive imposes a sinusoidal period on the linear motion of the piston and connecting rod. As generator associated with the piston produces a sinusoidal voltage in response to the liner motion of the piston and connecting rod.Type: GrantFiled: December 31, 2009Date of Patent: April 26, 2011Assignee: Achates Power, Inc.Inventors: James U. Lemke, William B. McHargue

Patent number: 7640910Abstract: An opposed piston, internal-combustion engine including a cylinder with a bore and opposed pistons disposed within the bore is provided with one or more hypocycloidal drives that convert the linear motion of a piston to rotary output motion. An electrical generator includes an opposed piston, internal-combustion engine with a coil mounted to the skirt of a piston and a hypocycloidal drive connected by a rod to the piston. The construction of the hypocycloidal drive imposes a sinusoidal period on the linear motion of the piston. As the piston transports the coil though a magnetic field, a sinusoidal voltage is induced in the windings of the coil.Type: GrantFiled: March 16, 2007Date of Patent: January 5, 2010Assignee: Achates Power, IncInventors: James U.

Patent number: 5317463Abstract: An information storage apparatus is disclosed for reading and/or writing information on a rigid storage medium which includes a liquid bearing interface between the transducer and medium instead of a conventional air bearing. The liquid is a fluorocarbon which has stable, self-lubricating, viscous and high-density properties. In an exemplary embodiment of a cockpit voice recorder/flight data recorder, low-density metallic components or composite parts of the rigid magnetic disk drive assembly with essentially the same density as the liquid achieve a near zero buoyancy configuration that obviates the effects of vibration and acceleration.Type: GrantFiled: September 10, 1993Date of Patent: May 31, 1994Assignee: Conner Peripherals, Inc.Inventors: James U.
