Abstract

A hydraulic fan circuit is disclosed. The hydraulic fan circuit may have a primary pump, a motor, a fan connected to and driven by the motor, and a flywheel connected to and driven by one of the motor and the fan. The hydraulic fan circuit may also have a supply passage extending from the primary pump to the motor, a return passage extending from the motor to the primary pump, and a diverter valve configured to selectively connect the supply passage to a low-pressure sump.
