Filed:

Jan 17, 2006

Appl. No.:

11/275574

Inventors:

Mario P. Boisvert - Reed City MI, US
Randall L. Perrin - Grawn MI, US
Marvin E. Puska - Marion MI, US
John E. Mitchell - Newaygo MI, US

Assignee:

Nartron Corporation - Reed City MI

International Classification:

F02D 29/06

US Classification:

290 40C, 290 29, 290 1 R, 290 40 B, 180 653, 180 654

Abstract:

Electronic control for a hydraulic system driving an auxiliary power source is provided, with specific application as a system for controlling the operation of a hydraulically driven AC generator. The system may includes a hydraulic pump, a hydraulic motor drivably connected to the generator, a fluid circuit for circulating fluid from the pump to the motor and back. The fluid circuit may contain a bypass conduit to bypass the motor. The system also includes a proportional servo control valve assembly for controlling the fluid circuits and a control circuit for controlling the proportional control valve assembly. The control system can be capable of controlling the flow of hydraulic fluid to the motor powering the electrical or mechanical system. Sensors for measuring the operating parameters of the system and an operator interface module can influence the operation of the system.
