VALVE ACTUATOR - A simplified explanation of the abstract
This abstract first appeared for US patent application 18189853 titled 'VALVE ACTUATOR
Simplified Explanation
The valve actuator described in the patent application is designed to control cooling water in a thermal management system for cooling a fuel cell. The actuator includes a motor, a gear assembly, and underwater bearings to facilitate the movement of the valve plate that controls the flow of cooling water. Cooling water is used to cool both the gear assembly and the motor.
- Motor with rotor, stator, and motor housing
- Gear assembly connected to valve rotation shaft
- Motor rotation shaft connected to gear assembly
- First underwater bearing between valve rotation shaft and gear housing
- Second underwater bearing between motor rotation shaft and gear housing

Original Abstract Submitted
A valve actuator of a cooling valve is configured to control cooling water in a thermal management system for cooling a fuel cell. The valve actuator includes a motor including a rotor, a stator, and a motor housing, a gear assembly including a gear housing and being connected to a valve rotation shaft of a valve plate configured to control a passage of cooling water, a motor rotation shaft configured to rotate the rotor is connected to the gear assembly, a first underwater bearing disposed between the valve rotation shaft and the gear housing, and a second underwater bearing is disposed between the motor rotation shaft and the gear housing. Cooling water introduced into the cooling valve is introduced into the motor housing and the gear housing to cool the gear assembly and the motor.
