Abstract: Product manifolds for use with portable oxygen concentrators and portable oxygen concentrators including such product manifolds. An example product manifold for use with a portable oxygen concentrator includes a body, a first product port, a second product port, an accumulator port, an output port, and a flow path. The flow path fluidly couples the first product port, the second product port, the accumulator port, and the output port. The product manifold includes a first control port, a second control port, and a third control port. The first, second, and third control ports fluidly couple the flow path. The product manifold also includes a first solenoid valve assembly, a second solenoid valve assembly, and a third solenoid valve assembly. The first, second, and third solenoid valve assemblies are secured to the body of the product manifold adjacent the first, second, and third control ports, respectively, by a corresponding snap fit connector.

Abstract: Product manifolds for use with portable oxygen concentrators and portable oxygen concentrators including such product manifolds. A product manifold for use with a portable oxygen concentrator includes a first product port, a second product port, an accumulator port, an output port, and a flow path. The flow path operatively coupling each of the first product port, the second product port, the accumulator port, and the output port to one another. The product manifold includes a plurality of control ports. Each of the control ports fluidly coupling the flow path. The product manifold includes a first orifice disposed in a first portion of the flow path; a second orifice disposed in a second portion of the flow path; and a third orifice disposed in a third portion of the flow path. Each of the first orifice, the second orifice, and the third orifice being formed by an electrical forming process and having a thickness of between about 0.0025 inches and about 0.004 inches.

Abstract: A system and method for a high flow valve includes a seal rod, an armature configured to be connected to and move the seal rod, a valve seal configured to be connected to the seal rod, an exhaust seal seat and a diaphragm. The valve seal is configured to be positioned on the exhaust seal seat and exert an exhaust seal pressure force. The diaphragm is configured to exert a diaphragm force opposite the exhaust seal pressure force to balance the exhaust seal pressure force.

Abstract: This present invention relates to a fluid flow control device, such as a valve in an internal combustion exhaust pipe. The fluid flow control device includes a valve assembly and an actuator assembly. The fluid flow control device further includes a cooling ring positioned between the actuator assembly and valve assembly in order to thermally isolate the sensors, controllers and other elements of the actuator assembly from heat that may be present in the valve assembly.

Abstract: This present invention relates to a remote electro-hydraulic actuator for actuating of mechanical devices, such as a valve in an internal combustion exhaust pipe. The actuator includes a multi-vane rotational assembly that flows the working fluid through strategically sized flow channels within the structure of the rotational assembly. The size of the holes are sized to help the stability of the valve and can also be provided with pressure check valves or reed valves to dampen the rotation of the valve and reduce any instabilities due to pulsations driven back via the output shaft.

Abstract: A control valve assembly for a load carrying vehicle that includes a dumping mechanism. The control valve assembly including a housing, a valve, and a biasing device. The valve is movable between a dumping position, and a closing position. The biasing device including a biasing device housing and a piston moveable between a first piston position and a second piston position relative to the biasing device housing. A biasing element is arranged between the biasing device housing and the piston to bias the piston toward the first piston position. The biasing device directly contacts the valve when in the first piston position to inhibit movement of the valve, and the biasing element is calibrated to allow the piston to move to the second piston position when air provided by an air compressor reaches a predetermined pressure, thereby not inhibiting movement of the valve.
