THROTTLE VALVE CONTROL DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18337494 titled 'THROTTLE VALVE CONTROL DEVICE
Simplified Explanation
The abstract describes a throttle valve control device that includes a valve, a motor, a coil spring, a rotation angle sensor, and a controller. The valve is located in a passage and opens and closes the passage by rotating with a shaft. The motor rotates the shaft to position it at the fully-closed, fully-open, or intermediate position of the valve. A coil spring applies a force to the shaft, and a rotation angle sensor detects the valve's opening degree. The controller is responsible for controlling the valve's position.
- The valve control device includes a valve that opens and closes a passage by rotating with a shaft.
- A motor is used to rotate the shaft and position it at the fully-closed, fully-open, or intermediate position of the valve.
- A coil spring applies a force to the shaft to assist in controlling the valve's position.
- A rotation angle sensor detects the opening degree of the valve.
- The controller executes different control strategies based on the valve's position, including fully-open side control, fully-closed side control, and valve intermediate-position control.
Potential Applications
- Automotive industry: Throttle valve control devices are commonly used in vehicles to regulate the flow of air or fuel mixture into the engine.
- Industrial machinery: This technology can be applied to control the flow of fluids or gases in various industrial processes.

- Versatile application: The throttle valve control device can be applied in various industries and systems, providing a flexible solution for flow regulation needs.
Original Abstract Submitted
A throttle valve control device includes a valve arranged in a passage of a body and rotating together with a shaft to open and close the passage. A motor rotates the shaft such that the shaft is located at a valve fully-closed position, a valve fully-open position, or a valve intermediate position which is between the valve fully-closed position and the valve fully-open position. A coil spring applies a spring force to the shaft. A rotation angle sensor detects an opening degree of the valve. A controller executes a valve intermediate-position control within a range between a fully-open side threshold and a fully-closed side threshold between which the valve intermediate position is interposed. Outside the range, the controller executes a fully-open side control and a fully-closed side control which are different from the valve intermediate-position control.
