A method of providing fluid flow control in a gas separation device for separating oxygen gas from air, comprising:
- providing a gas separation device for separating oxygen gas from air, the gas separation device including a flow control mechanism with a valve assembly, the need valve assembly including a motor, a valve body, a plunger in the valve body reciprocally driven by the motor, the valve body including a fluid inlet, a fluid outlet, and a flow chamber therebetween, the flow chamber including a flow chamber wall and a flow chamber outlet, the plunger including a flexible member that reciprocates within the flow chamber outlet to provide variable flow control therethrough, the flexible member including a lip seal that engages the flow chamber wall during reciprocation of the plunger and flexible member to provide a seal therebetween;
- separating oxygen gas from air using the gas separation device and controlling product flow in a flow control mechanism using the valve assembly by:
- supplying fluid flow to the fluid inlet of the valve assembly;
- providing variable flow control in the valve assembly through reciprocation of the flexible member in the flow chamber outlet;
- sealably engaging the flow chamber wall with the lip seal of the flexible member to prevent fluid flow therebeween.
A gas separation device for separating oxygen gas from air, comprising:
- a compressor that receives ambient air;
- a concentrator that receives the air under high pressure from the compressor;
- separates oxygen from air, and delivers oxygen as a product fluid;
- a measurement mechanism that measures characteristics of the product fluid;
- a flow control mechanism that controls delivery of the product fluid, the flow control mechanism including:
- a valve assembly for providing fluid flow control, comprising:
- a motor;
- a valve body;
- and
- a plunger within the valve body and reciprocally driven by the motor,
- wherein the valve body including a fluid inlet, a fluid outlet, and a flow chamber therebetween, the flow chamber including a flow chamber wall and a flow chamber outlet, the plunger including a flexible member reciprocating within the flow chamber outlet to provide variable flow control therethrough, the flexible member including a lip seal engageable with the flow chamber wall during reciprocation of the plunger and flexible member to provide a seal therebetween.
