Hydraulic system of single frequency and double amplitude vibration opening of natural gas solenoid valve for vehicle. For vibratory road roller, it is required that in the process of pressing, when it is necessary to stop vibration or change the amplitude, it can stop rotating rapidly in the range of 1.5~1.7s, so as not to impact the compacted surface due to vibration and affect the compacted quality. Common M - type three - position four - way directional valve. In the middle position of the slide valve, cut off A and B two working oil ports, will produce A large back pressure, make the motor overcome the moment of inertia of the shaker, quickly stop rotation. Although this method avoids the real-time indentation of road pressure, the instantaneous pressure peak of motor circuit is large, and the damage rate of motor and related parts is high. For this reason, two relief valves are usually set at the oil ports of reversing valve A and B to protect the system. In a word, automatic regulating solenoid valve in the selection of reversing valve, must be based on the working characteristics of the working mechanism, choose the appropriate neutral function.

Three-position four-way solenoid directional valve is developed for G series forklift truck and has obtained patent.
