Patent number: 8863704Abstract: A liquid-cooling engine system is described with a coolant control device having an adjustable control element capable of independently controlling the flow of coolant through a cylinder head and cylinder block. The device contains a rotatable drum that can be rotated along its longitudinal axis to expose holes and thereby allows coolant circulation based on a temperature within the engine system. The coolant control device has three positions but may also be fine-tuned within each position to control the flow of coolant through the cylinder head and cylinder block in order to adjust the amount of heat extracted according to demand, which serves to control the liquid-type cooling circuit in a demand-dependent manner that accounts for the operating modes of the internal combustion engine.Type: GrantFiled: January 2, 2013Date of Patent: October 21, 2014Assignee: Ford Global Technologies, LLCInventors: Jan Mehring, Hans Guenter Quix

Publication number: 20080006228Abstract: An engine that has expandable cylinders receives its pressure from a steam boiler or any other expanding, external gases, and/or liquid devices. The motor or pump is made of, encased, reciprocating spheres and toroidal cavities that are located in the outer wheels allowing said balls to cam in and out, rotating the said outer wheels. The steam, gases or liquid is presented under pressure at the intake sliding type valve of the motor and the cam action of the piston (balls) creates a closed chamber which causes the chambers (cylinders) to expand and the outer wheels to turn. A sliding exhaust valve then opens up to expel the expended material (steam) aided by the balls. The balls are then cammed to the opposite side creating a seal for that chamber and the action repeats. A pressurized lubricant is introduced via the ball tubes enhancing the chamber seals. The outer wheels are surfaced to the middle block at a close tolerance to make a lubricated seal.Type: ApplicationFiled: July 5, 2006Publication date: January 10, 2008Inventor: Forest Frank Liebe
