Patent ID: 11360496

Abstract:
The invention relates to a valve device (1) having a pressure regulator (3) for a flowing gas and a housing (4). The pressure regulator (3) includes a diaphragm (31), a spring (34), a control actuator (32), and a control seat (33). The control actuator (32) includes a plate-like portion (32′) and a rod-like portion (32″) adjacent to one side of the plate-like portion (32′), the control seat (31) encompassing the rod-like portion (32″) of the control actuator (32). The diaphragm (31) and the control actuator (32) are mechanically coupled to each other such that an axial movement of the control actuator (32) moves the diaphragm (31). In addition, the spring (34) and the control actuator (32) are mechanically coupled to each other. The control seat (33) limits a movement of the control actuator (32). In one state, the control seat (33) and the control actuator (32) prevent the gas from flowing. The control seat (33) is configured as a ring arranged in a recess (40) of the housing (4).
