Throttle Valve Control Device - A simplified explanation of the abstract
This abstract first appeared for US patent application 18557767 titled 'Throttle Valve Control Device
The present application invention aims to provide a throttle valve control device that effectively cools a bearing of a throttle shaft while preventing an increase in the size of a throttle body.
- The diameter of the first bearing of the throttle shaft is greater than the diameter of the second bearing.
- Flow paths for a heat exchange medium are formed in the throttle body, along the outer periphery of an intake passage, overlapping with the second bearing.
- The inlet and outlet portions of the flow paths are positioned to sandwich the first bearing.
Potential Applications: - Automotive industry for engine throttle control systems - Industrial machinery with throttle valve mechanisms
Problems Solved: - Preventing overheating of bearings in throttle valve control devices - Avoiding size increase of throttle bodies due to cooling mechanisms
Benefits: - Improved durability and longevity of throttle valve components - Enhanced performance and efficiency of engine systems
Commercial Applications: Throttle valve control devices can be used in various automotive and industrial applications, providing reliable and efficient throttle control for engines.
Questions about Throttle Valve Control Devices: 1. How does the design of the flow paths contribute to the cooling of the throttle shaft bearing? 2. What are the key differences between the first and second bearings in the throttle valve control device?
Original Abstract Submitted
An object of the present application invention is to provide a throttle valve control device capable of effectively cooling a bearing of a throttle shaft while preventing an increase in size of a throttle body. Therefore, in a throttle valve control device in which flow paths T to T through which a heat exchange medium flows are formed in a throttle body , the diameter of a first bearing of a throttle shaft is greater than the diameter of a second bearing , the flow paths T to T are disposed along an outer periphery of an intake passage to overlap with the second bearing when viewed from a flow direction of the intake passage , and an inlet portion T and the outlet portion T of the flow paths T to T are disposed to sandwich the first bearing
