Appl. No.:

13/026843

Inventors:

Joshua Aaron Tolbert - Tuscaloosa AL, US
Robert Tracy Tolbert - Arley AL, US
Benjamin Jeffrey Tolbert - Tuscaloosa AL, US

International Classification:

F01L 1/34

US Classification:

123 9016

Abstract:

This invention will provide a means for the lobe separation angle of the camshaft between the intake and exhaust valves of an internal combustion engine, or any other piston type machine, using a camshaft and valves to control the air flow into and/or out of the engine or piston type pumping or power machine, to vary as the engine or machine operates. This invention will effectively reduce or increase the angular measurement from the intake lobe centerline to the exhaust valve lobe centerline during operation. This modulation of the valve events may be controlled by a computer, manually or automatically. This modulation of the valve events may be controlled by an operator, whether manually or semi-automatically. This modulation of the valve events may be controlled by some other means. The invention will be commanded by an external command to change the valve events as the engine or machine operates and the invention will then change the valve events of the intake valve(s), the exhaust valve(s) or both. In an internal combustion engine, whether spark ignited or combustion ignited, this invention will greatly modify the operating characteristics of the engine as to power output, operation speeds, fuel economy, emissions output, heat production of the engine and other operating characteristics.

Abstract:

A hydrostatic drive, to operate rotational industrial equipment such as a fan, a pump, a compressor, a conveyor or other drive used in industrial settings. The invention utilizes one or more variable displacement pump(s) configured to drive one or more fixed displacement hydraulic motor(s), or utilizing one or more fixed displacement pump(s) configured to drive one or more variable displacement hydraulic motor(s) or utilizing one or more variable displacement pump(s) configured to drive one or more variable displacement hydraulic motor(s). The pump(s) is powered by a fixed speed or variable speed motor or engine, most likely a fixed speed electric motor. The motor operates the rotational equipment with the purpose of process control, efficiency, and/or energy conservation.
