ヨン装置。[Scope of Claim for Utility Model Registration] An actuator that is interposed between the vehicle body side and the wheel side and can change the vehicle height according to internal hydraulic pressure; and an actuator that is connected to the actuator via an output circuit and that is based on a control signal. a pressure control valve capable of changing output hydraulic pressure; a hydraulic sealing means provided in a hydraulic pressure transmission system to the actuator and configured to be able to contain hydraulic pressure within the actuator; A communication passage that connects the hydraulic fluid in the room so that it can flow; and a valve that is provided in the middle of the communication passage and is normally closed to block the communication passage, and that communicates the communication passage when the hydraulic pressure sealing means is in a filling operation. The first valve to be opened in the state
a cut valve; a relief circuit connected to the communication path; a second cut valve that is provided in the relief circuit and opens and closes to communicate and cut off the relief circuit in response to a valve open signal and a valve close signal; the control signal for forming a predetermined vehicle attitude based on an input signal from an input means including a high-speed sensor;
In addition to outputting a valve opening signal and a valve closing signal, when the hydraulic pressure sealing means is activated and the first cut valve is opened, the vehicle height based on the input signal from the vehicle height sensor is set to a predetermined vehicle height. A vehicle suspension device comprising: a controller that outputs a valve opening signal when the vehicle height is higher than the vehicle height, and outputs a valve closing signal when the vehicle height is lower than a predetermined vehicle height.
