Abstract: A hydraulic manifold has features adapted to the needs of hybrid vehicle applications. In one embodiment, multifunction valves selectively regulate fluid flow among primary and auxiliary flow paths. A normally closed butterfly valve is biased by a relatively small secondary biasing force against rotation in first and second (opposite) directions, and by a relatively large principal biasing force against rotation in the first direction past a transitional angular position at which the principal biasing force takes effect. An actuator selectively controls the transitional angular position and the magnitude of the principal biasing force. In the first direction, flow must overcome only the secondary biasing force to pass the valve. In the second direction, any flow sufficient to overcome the secondary biasing force but not the principal biasing force will divide into a first flow passing the valve and a second flow induced to enter an auxiliary path upstream.

Abstract: A shunt valve assembly includes an electromechanical brake mechanism that locks a position of a pressure setting mechanism within a shunt valve assembly. The electromechanical brake can maintain the position of the pressure setting mechanism in the presence of a relatively strong magnetic field to maintain a set pressure differential within the shunt valve assembly. In certain cases, the shunt valve requires repositioning of the pressure setting mechanism within the shunt valve assembly to adjust a fluid flow rate through the shunt valve assembly.

The shunt valve assembly utilizes the signal to activate the braking mechanism and unlock the pressure setting mechanism. The clinician then operates the controller to non-invasively reposition the pressure setting mechanism and adjust the pressure at which the shunt valve opens.

Abstract: The current invention describes a pressure regulator for a gas burner that allows a consumer to make adjustments to the pressure regulator for differences in altitude as well as differences in the design and manufacturing tolerances of the pressure regulator from the manufacturer. Many traditional gas burners require a third party, with specialized equipment and training, to make corrective adjustments to the pressure to a gas burner after the burner is sold to the consumer. This pressure regulator incorporates a regulating curve into the pressure regulator, thus eliminating the need to remove the pressure regulator from the appliance and allowing the consumer himself to make the necessary adjustments to the burner without the assistance of a third party.
