PROBLEM TO BE SOLVED: To provide a solenoid valve unit capable of improving the portability of unit itself by minimizing use of a hose or the like for supplying and discharging fluid, and being used in various applications.SOLUTION: A solenoid valve unit includes a first solenoid valve 4a for controlling suction of a carbon dioxide gas from a fluid suction port 11 and supply of the carbon dioxide gas from a fluid supply port 12, a second solenoid valve 4b for controlling discharge of the carbon dioxide gas from a fluid discharge port 13, and a solenoid valve unit transmitting/receiving portion for communicating with a remote controller transmitting/receiving portion of a remote controller via wireless communication. The first solenoid valve 4a is opened by operation from a remote controller operation button of the remote controller to suck the carbon dioxide gas from the fluid suction port 11, so that the carbon dioxide gas is supplied to a lifting device from the fluid supply port 12 and the lifting device is raised. The second solenoid valve 4b is opened by operation from the remote controller operation button of the remote controller, so that the carbon dioxide gas is discharged from the fluid discharge port 13 and the lifting device is lowered.SELECTED DRAWING: Figure 2 |
