A throttle valve assembly is disclosed having a throttle valve mounted within a throttle body to vary the flow of air therethrough. The throttle valve comprises of first and second throttle plates that interact with one another so as to be configurable in a V-shape thereby forming a converging/diverging flow path through part of the throttle body in which the flow of air through the throttle body is restricted and in flat aligned configuration which is minimally intrusive so as to produce substantially no restriction to flow through the throttle body is produced by the throttle valve.

A spring return throttle actuator including: an electric, plural-coil DC motor having an output shaft, a throttle return spring, a gear transmission connected to the output shaft, a control unit adapted to control power supply to the DC motor, wherein the spring return throttle actuator has a movement range between closed throttle and fully opened throttle. The control unit includes a monitoring circuit adapted to monitor DC motor movement. The monitoring circuit is configured to receive signals from at least one voltage sensor adapted to sense voltage induced in at least one of the DC motor coils during a spring forced return of the throttle, and the monitoring circuit is configured to create a representation of DC motor movement based on said signals.

An electric throttle device and a controlling system used for a portable gasoline engine may include a rotation shaft and a throttle mounted on the rotation shaft, the throttle working to open or close the intake channel, and may further include a power unit, a transmission unit in a transmission connection with the power unit, and a controller. The transmission unit is matched with the rotation shaft, and the controller includes a circuit driving module for driving the power unit to control the opening or closing of the throttle. The electric throttle device enables co-movement of the throttle and the choker as well as automatic opening or closing.

A reciprocating internal combustion engine with an emission control device and a method for operating same are described. At least one throttle, arranged on the intake side, at least one main fuel injection nozzle for feeding a main fuel to a combustion chamber of the diesel engine, and at least one catalytic converter are arranged in the center of an exhaust gas passage for conducting exhaust gas out of the combustion chamber, and at least one control device is used. A soot burn-off rate determined according to a model approach is maximized using a regulation process by means of a throttle valve.

An engine device includes a main throttle valve disposed at a portion where an outlet of a supercharger and an inlet of an intercooler are coupled to each other, an exhaust bypass flow path configured to couple an outlet of an exhaust manifold to an exhaust outlet of the supercharger, an exhaust bypass valve disposed in the exhaust bypass flow path, an air supply bypass flow path configured to bypass a compressor of the supercharger, and an air supply bypass valve disposed in the air supply bypass flow path. Within a low load range of a load on the engine device, when the load is lower than a predetermined load, feedback control is performed on the main throttle valve, and when the load is higher than the predetermined load, map control based on a data table is performed on the main throttle valve.

The Intelligent Fault Tolerant Throttle Body prevents unintended acceleration of vehicles. This invention solves this emergency by returning the throttle plate to a safe position when commanded by a driver Emergency Button or by brake actuation. The device is installed on a conventional throttle body and comprises an Emergency Button (EB) and a Throttle Motor Controller (TMC). The TMC is a micro controller contained inside the throttle body assembly that intercepts and modifies signals from the engine control unit (ECU) to the Throttle Body Motor (TBM) and monitors the brake switch signal and the throttle position sensor (TPS). The TMC has an internal accelerometer and a throttle pedal sensor input as well as other sensors which are used as additional confirmation of a true unintended acceleration condition and not resulting from ECU, wiring or sensor failures.

A method of making a throttle body assembly, includes casting a main body portion having a passage there through and mounting features for pivotally mounting a throttle valve within the passage. An annular spigot is formed by 3-dimensional printing and is welded to the main body portion in order to provide a quicker less expensive method of prototyping.

A vehicle comprises an engine including a plurality of combustion chambers; a plurality of throttle valves provided in the plurality of combustion chambers corresponding to the plurality of combustion chambers, respectively, to independently adjust flow rates of intake air flowing into the combustion chambers, respectively; two or more driving mechanisms for electrically driving the plurality of throttle valves divided into two or more groups in such a manner that each of the driving mechanisms drives the throttle valve in a corresponding group of the groups; and a throttle control device for controlling the driving mechanisms based on an amount of throttle operation information input by a rider and a predetermined vehicle state, wherein the throttle control device provides throttle opening rate commands which are made different between the groups, to the driving mechanisms, respectively, when a predetermined output adjustment condition is met.

A surgical stapler including an anvil, a staple cartridge, and a buttress material removably retained to the anvil and/or staple cartridge. In various embodiments, the staple cartridge can include at least one staple removably stored therein which can, when deployed, or fired, therefrom, contact the buttress material and remove the buttress material from the anvil and/or staple cartridge. In at least one embodiment, the anvil can include at least one lip and/or groove configured to removably retain the buttress material to the anvil until deformable members extending from the surgical staple are bent by the anvil and are directed toward and contact the buttress material.

The invention relates to a verification module (118) for verifying accuracy of a controller (116). The controller (116) is arranged to generate a demand based on a first input and a second input. The verification module (118) comprises; a calculation module (120) arranged to calculate an expected demand; a correction module (122) arranged to calculate an error between the demand and the expected demand and modify the expected demand to reduce the error; and a limiter (136) arranged to limit the demand in response to the error being greater than a threshold.
