Actuator for vehicle coolant control valve

An actuator for a vehicle coolant control valve to control a flow of coolant, the actuator comprising:

• a drive unit to generate driving power;
• an output unit which is connected to the drive unit and drives a control valve using the driving power;
• and
• a sensing unit including a printed circuit board to sense an output condition of the output unit,
• wherein a position sensor to sense a position of the output unit and an electro-magnetic compatibility (EMC) filter to filter EMC share the printed circuit board of the sensing unit,
• wherein the output unit includes:
• an output gear that rotates around an output shaft by the driving power of the drive unit;
• and
• an interference member, which is prepared to partially cover one surface of the output gear to thus face the printed circuit board and is communicated with rotation of the output gear, and
• wherein the output gear and the interference member are made of different materials from each other.

An actuator for a vehicle coolant control valve, the actuator comprising:

• a drive unit to generate driving power;
• an output unit to drive a control valve, which selectively opens/closes (“switches”) a coolant flow for a vehicle using the driving power provided by the drive unit;
• and
• a sensing unit to sense an output condition of the output unit,
• wherein the sensing unit is provided with a position sensor to sense a position of the output unit and an electro-magnetic compatibility (EMC) filter to filter EMC,
• wherein the drive unit includes:
• a driving source which is prepared to be adjacent to the sensing unit and has a cylindrical shape, and
• at least one transfer gear which is connected to the driving source to reduce a speed of the driving power and transfer the same to the output unit, and
• wherein the driving source is supported on a ground plate having a rounding shape and has at least two ground contact points when the driving source is compressed to the ground plate, wherein one side thereof is connected to the sensing unit.
