摘要： A two-stage valve for controlling the flow of gas from a pressurized gas supply with an upper main body including a cavity; a lower main body with at least one flow exhaust passage forming a primary flow path through the two-stage valve; a pre-stressed diaphragm sandwiched between the upper and lower main bodies, and pressure control capability for controlling the pressure in the cavity. A secondary flow path exists from the pressurized gas supply through the lower main body, through the upper main body, and terminating in the cavity in the upper main body. A first valve is installed in the secondary flow path to open and close the flow of gas from the pressurized gas supply to the cavity. A second valve installed in an exhaust passage in the upper main body allows the pressure in the cavity to exhaust to the environment. When the second valve is closed, the pressure in the cavity in the upper main body can be increased to lower the pre-stressed diaphragm. Raising and lowering of the pressure in the cavity causes the pre-stressed diaphragm to open and close the flow of gas from the pressurized gas supply through the primary flow path of the two-stage valve. The design of the two-stage valve and its components lends itself to constructing the two-stage valve as a microvalve using Micro-Electro-Mechanical Systems (MEMS) concepts.

摘要： A two-stage valve for controlling the flow of fluid from a pressurized fluid supply with an upper main body including a cavity with a contoured inner surface; a lower main body with at least one flow exhaust passage forming a primary flow path through the two-stage valve; a pre-stressed diaphragm sandwiched between the upper and lower main bodies, and pressure control capability for controlling the pressure in the cavity. A first valve opens and closes the flow of gas from the pressurized gas supply to the cavity. A second valve allows the pressure in the cavity to exhaust to the environment. Raising and lowering of the pressure in the cavity causes the pre-stressed diaphragm to open and close the flow of gas from the pressurized gas supply through the primary flow path of the two-stage valve. The design is suitable as a microvalve using Micro-Electro-Mechanical Systems (MEMS) concepts.
