Patent number: 11041637Abstract: Systems and methods utilize a cogeneration system for providing heating, cooling, and/or electricity to an enclosure. The system includes a heat engine for heating and supplying electricity to the enclosure. Coupled to the heat engine is a first conduit configured to transfer fluid from the heat engine to the enclosure to transfer thermal energy from the fluid to the enclosure. The system further includes a heat pump configured to supply at least heating and cooling to the enclosure. Coupled to the heat pump is at least a second conduit. The second conduit is configured to move fluid from the heat pump to the enclosure to transfer thermal energy from the fluid to the enclosure.Type: GrantFiled: June 25, 2018Date of Patent: June 22, 2021Assignee: IMBY Energy, Inc.Inventor: Steve Walker

Patent number: 9593641Abstract: An exemplary piston may include a piston body having radially inner and outer body mating surfaces. The piston may further include a cooling gallery ring cooperating with the piston body to form a continuous upper combustion bowl surface and a cooling gallery. The cooling gallery ring may have radially inner and outer ring mating surfaces abutted along their corresponding radially inner and outer body mating surfaces, such that the cooling gallery is substantially enclosed. The piston body and cooling gallery ring may be joined together along the radially inner and radially outer interface regions to form a generally one-piece piston assembly. The radially outer interface region may be elongated in a direction parallel to the piston axis, e.g., facilitating a laser welding joining process.Type: GrantFiled: September 20, 2012Date of Patent: March 14, 2017Assignee: MAHLE International GmbHInventors: Dieter Gabriel, Wolfgang Rein, Steve Walker, Volker Weisse, Michael Ulrich

The piston also includes a skirt having a crown connecting portion. The crown connecting portion is defined, at least in part, by a first skirt mating portion, a second skirt mating portion, and a skirt chamber surface extending between the first skirt mating portion and the second skirt mating portion. The first crown mating portion is selectively coupled to the first skirt mating portion. The second crown mating portion may be selectively coupled to the second skirt mating portion to define a piston chamber.Type: GrantFiled: April 9, 2012Date of Patent: August 12, 2014Assignee: Mahle International GmbHInventors: Steve Walker, Philip Vaden

Patent number: 7918155Abstract: A piston for an internal combustion engine is provided. The piston crown includes an interior surface that defines at least in part a cooling gallery and a cooling gallery surface within the piston. An annular surface may defines at least in part an annular passageway that allows fluid communication between an outer surface of the piston and the cooling gallery. Opposing annular surfaces may be abutted with a predetermined force, thereby limiting fluid flow from the cooling gallery to an outer surface of the piston. Further, an annular surface may extend into the cooling gallery to form a deflector along the cooling gallery surface, thereby limiting fluid flow from the cooling gallery to an outer surface of the piston.Type: GrantFiled: December 12, 2007Date of Patent: April 5, 2011Assignee: Mahle International GmbHInventors: Michael T. Lapp, Juan Gildemeister, Steve Walker, Stan Sorin
