摘要
A double operate check valve used in a hydraulic pressure circuit for locking and unlocking a vibration absorbing hydraulic cylinder included in a wheel suspension mechanism of a vehicle, which includes an improvement in its structure for providing the suspension with improved compliance with respect to road surface undulation and corresponding comfortable drive of the vehicle. The check valve pilot pistons have fluid conducting surfaces which are connected by a valve body passageway and which communicate the main fluid paths when hydraulic pressure in the pilot chamber urges the pilot pistons to open the check valves.
