Abstract
A coolant control valve includes an actuator, at least one valve body, an outer housing, and a temperature sensor having a first flow state and a second flow state. The first and second flow states can be achieved by first and second axial positions of the temperature sensor.
Claims14
A coolant control valve comprising:
- an actuator;
- at least one valve body actuated by the actuator;
- an outer housing having:
- at least one inlet;
- and,
- at least one outlet;
- and,
- a temperature sensor configured to move via a pressurized fluid that contacts the temperature sensor, the temperature sensor having:
- a displaceable body extending both inside of the outer housing and outside of the outer housing, the displaceable body having an electrical connector configured to move together with the displaceable body and communicate electronically with an electronic controller to provide a fluid temperature sensed by the temperature sensor;
- and,
- the displaceable body movable to:
- i) a first axial position corresponding to a first flow state, and ii) a second axial position corresponding to a second flow state, and in the second axial position, the displaceable body extends outside of the outer housing further than in the first axial position.

A method of operating a coolant control valve, comprising:
- flowing pressurized fluid through an outer housing of the coolant control valve configured with a temperature sensor, the temperature sensor having a displaceable body with an electrical connector configured to move together with the displaceable body and communicate electronically with an electronic controller to provide a fluid temperature sensed by the temperature sensor;
- generating an actuation force on the temperature sensor, the actuation force provided by the pressurized fluid contacting the temperature sensor;
- and
- moving the displaceable body of the temperature sensor in a first axial direction via the actuation force from a first axial position to a second axial position that forms a passageway that fluidly connects an inner chamber of the coolant control valve to an outlet, and
- in the second axial position, the displaceable body extends outside of the outer housing further than in the first axial position.
