Fluid control device, valve module and pneumatic comfort system

By designing the on/off valve section in the fluid control device to control the opening and closing of the distribution valve section and the pressure regulating valve section, active adjustment of air pressure and reduction of valve module size are achieved. This solves the problems of excessive size and inability to actively regulate pressure in the prior art, and meets the airbag's differentiated air pressure control requirements.

AI Technical Summary

Technical Problem

The existing valve module is too large and cannot achieve active pressure regulation, which cannot meet the different pressure control requirements of different airbags.

Method used

Design a fluid control device that connects a distribution valve section and a pressure regulating valve section through a switching valve section. The switching valve section controls the on/off state of the distribution valve section and the pressure regulating valve section to achieve active regulation of air pressure. The length of the air intake path is reduced by connecting the pressure regulating valve section in series with the vent end of the distribution valve section.

Benefits of technology

It achieves active pressure regulation with controllable air pressure, reduces the size of the valve module, ensures precise control of the air intake path and controllable adjustment of air pressure, and meets the air pressure requirements of different airbags.
