Patent number: 8753100Abstract: A fluid transfer engine employs a case with a cylindrical inner wall having an operating radius extending from a case axis. A main rotor is carried within the case and incorporates a lobe with a major radius equal to and concentric with the operating radius of the case, the main rotor having a minor radius defining a body. Two peripheral rotors are diametrically opposed with respect to the case axis and rotate within rotor chambers extending from the case. Each peripheral rotor has a radius equal to the minor radius and a center of rotation located at twice the minor radius from the case axis. Each of the peripheral rotors rotates in uniform circular motion with the main rotor in sealing contact with the body and incorporates a sculpted recess for receiving the lobe of the main rotor.Type: GrantFiled: June 12, 2012Date of Patent: June 17, 2014Assignee: Gyroton CorporationInventors: William R. Peitzke, Matthew Brown, James G. P. Dehlsen, Christopher J. Grieco

Patent number: 7493885Abstract: An asymmetric complete-expansion thermodynamic engine cycle is provided by an engine which compresses an air/fuel mixture to a given ratio, ignites and combusts the mixture, and expands the products through a power stroke to a volume substantially larger than the compression volume before being vented and purged to the atmosphere. This cycle is performed by a non-axisymmetric main rotor revolving within a cylindrical housing. Sealing means associated with the main rotor provide for the varied compression and expansion volumes. The cylindrical housing also contains means for air intake, fuel injection, venting, and spent gas exhaust porting.Type: GrantFiled: July 25, 2005Date of Patent: February 24, 2009Assignee: Gyroton CorporationInventors: William R.

Patent number: 6955153Abstract: A thermodynamic cycle for an internal combustion rotary engine is disclosed which achieves high efficiency through an asymmetry between the volume of air charge before compression and the volume of expanded air at the completion of expansion. The expanded volume is ideally selected such that the pressure of the exhaust gases is near the ambient pressure of the intake air. Three embodiments of engines which utilize the cycle are disclosed, one with the major components operating in uniform circular motion, one which utilizes lobe valves, and one which utilizes three sets of lobe valves such that three charges of air at various stages in the cycle are in the engine, thus increasing the power density of the engine.Type: GrantFiled: May 12, 2000Date of Patent: October 18, 2005Assignee: Gyroton CorporationInventors: William R.
