A controller is for a vehicle wetting system including a fluid supply and a delivery line having an inlet connected with the supply and an outlet located to direct fluid onto a compacting drum. The controller includes a regulator configured to adjust a fluid flow rate through the outlet. A speed sensor connected with the vehicle senses vehicle speed. Further, a logic circuit connected with the sensor and the regulator automatically operates the regulator such that the regulator adjusts the flow rate to be generally proportional to the vehicle speed. Alternatively, the logic circuit permits flow through the outlet for a predetermined drum displacement and alternately interrupts flow for a predetermined period of time. The regulator is either a shunt line and a valve adjusting flow through the shunt line to adjust flow through the outlet or a pump regulator controlling flow from a pump in the delivery line.

Controller for a compacting vehicle wetting system

A vibratory compactor includes front and rear frame portions driven by a first hydraulic motor and a vibration mechanism on at least one of the frame portions also driven by a second hydraulic motor. A first sensor on the vehicle senses movement of a member on said vehicle driven by said first hydraulic motor, and sends corresponding signals to a microcontroller on the vehicle. A timing device sends timing signals to the microcontroller, which is programmed to convert the movement signals and timing signals to indicate longitudinal speed of travel of the vehicle. The microcontroller automatically turns a vibration means on the vehicle on or off depending on the speed of the vehicle. A second sensor on the vehicle sends a signal to the microcontroller indicating a reverse direction of travel of the vehicle. The microcontroller automatically coincides the direction of motion of the vibration means with the direction of travel of the vehicle.
