この油圧モータへの油の流れを制御する制御弁が
設けられた舗装車両の走行速度制御装置において
、前記制御弁に並列に流量補正弁が設けられ、こ
の流量補正弁は、前記油圧モータの供給圧力の増
大に伴つて開口面積が増大し、同一の供給圧力に
対して該流量補正弁を通過する流量が油圧モータ
の漏れ量に等しくなるように構成されていること
を特徴とする舗装車両の走行速度制御装置。 A hydraulic motor is provided to drive the traveling drive wheels.
In a traveling speed control device for a paving vehicle that is provided with a control valve that controls the flow of oil to the hydraulic motor, a flow rate correction valve is provided in parallel with the control valve, and this flow rate correction valve is configured to control the flow of oil to the hydraulic motor. A paving vehicle characterized in that the opening area increases as the pressure increases, and the flow rate passing through the flow rate correction valve for the same supply pressure is equal to the leakage amount of the hydraulic motor. Travel speed control device.
