Abstract: A hydraulic motor drive system is disclosed. The hydraulic motor drive system includes a pump, a flow control module fluidly coupled to a discharge of the pump via a first conduit, and a hydraulic motor fluidly coupled to the flow control module via a second conduit and a third conduit, and a controller operatively coupled to the flow control module. The controller is configured to operate the flow control module in a first mode, such that the flow control module blocks fluid communication between the pump and the hydraulic motor via the second conduit, and effects fluid communication between the pump and the hydraulic motor via the third conduit, and operate the flow control module in a second mode, such that the flow control module effects fluid communication between the pump and the hydraulic motor via the second conduit.

Abstract: A machine includes a hydraulic fan system for circulating cooling air through an engine compartment. Periodically, the fan rotation direction is briefly reversed in order to dislodge any material debris that may have accumulated at the inlet to the engine compartment. When a fan reversal event is initiated, the fan motor will continue to rotate due to angular momentum even after the pump output flow has been switched from a first motor port to a second motor port. During this continued rotation as the fan decelerates to zero speed, vacuum pressure levels can arise at the first motor port, and a pressure spike can develop at the second motor port. In order to alleviate these conditions, a pressure transfer valve briefly opens to facilitate fluid flow directly from the second motor port to the first motor port as the fan motor decelerates towards zero speed before reversing direction, simultaneously alleviating vacuum and pressure spike conditions.
