Abstract

A hydraulic fan circuit (10) is disclosed. The hydraulic fan circuit may have a primary pump (14), a high-pressure passage (26) fluidly connected to the primary pump, and a low-pressure passage (24) fluidly connected to the primary pump. The hydraulic fan circuit may also have at least one accumulator (68, 70) in selective fluid communication with at least one of the high- and low- pressure passages, a motor (18), and a fan (20) connected to the motor. The hydraulic fan circuit may further have a fan isolation valve (84) fluidly connected to the high- and low-pressure passages. The fan isolation valve may be movable between a flow-passing position at which the motor is fluidly connected to the primary pump via the high- and low-pressure passages, and a flow-blocking position at which the motor is substantially isolated from the primary pump.
