Abstract
This present invention relates to a fluid flow control device, such as a valve in an internal combustion exhaust pipe. The fluid flow control device includes a valve assembly and an actuator assembly. The fluid flow control device further includes a cooling ring positioned between the actuator assembly and valve assembly in order to thermally isolate the sensors, controllers and other elements of the actuator assembly from heat that may be present in the valve assembly.
Claims20
A fluid flow control device, comprising:
- a valve assembly comprising:
- a valve housing, and
- a movable valve element;
- an actuator assembly comprising:
- an actuator housing, and
- a movable actuator element;
- a shaft connecting the movable actuator element with the movable valve element;
- and
- a first cooling ring positioned between a surface of the valve housing and a surface of the actuator housing, the cooling ring comprising:
- a first surface facing toward the valve assembly, a second surface facing toward the actuator assembly, a cooling channel, and a cooling inlet port that extends through the first surface.
A fluid flow control device, comprising:
- a valve assembly comprising:
- a valve housing, and
- a movable valve element;
- an actuator assembly comprising:
- an actuator housing, and
- a movable actuator element;
- a shaft connecting the movable actuator element with the movable valve element;
- and
- a cooling ring positioned between a surface of the valve housing and a surface of the actuator housing,
- the cooling ring comprising:
- a first surface adjacent to the valve assembly, a second surface adjacent to the actuator assembly, a cooling channel containing cooling fluid, and a cooling inlet port that extends through the second surface.
A fluid flow control device, comprising:
- a valve assembly comprising:
- a valve housing,
- a valve housing fluid passage extending through a portion of the valve housing, and
- a movable valve element;
- an actuator assembly comprising:
- an actuator housing,
- an actuator housing fluid passage extending through a portion of the actuator housing, and
- a movable actuator element;
- a shaft connecting the movable actuator element with the movable valve element;
- and
- a first cooling ring positioned between a surface of the valve housing and a surface of the actuator housing, the cooling ring comprising:
- a first surface facing toward the valve assembly, a second surface facing toward the actuator assembly, a cooling channel containing cooling fluid, a first cooling port that extends through the first surface and is fluidly connected with the valve housing fluid passage, and a second cooling port that extends through the second surface and is fluidly connected with the actuator housing fluid passage.
