Abstract
A coolant control valve for an internal combustion engine, including: a housing; a rotary valve disposed within the housing, the rotary valve including an axis of rotation and an end stop extending in a radial direction toward the axis of rotation; and a resilient element connected to the housing. In a circumferential position of the rotary valve about the axis of rotation: a circle, centered on the axis of rotation, passes through the resilient element and the end stop; and the end stop is in contact with the resilient element.
Claims20
A coolant control valve for an internal combustion engine, comprising:
- a housing;
- a first rotary valve disposed within the housing, the first rotary valve including:
- an axis of rotation;
- and,
- an end stop extending in a first radial direction toward the axis of rotation;
- and,
- a resilient element connected to the housing, wherein in a first circumferential position of the first rotary valve about the axis of rotation:
- a circle, centered about the axis of rotation, passes through the resilient element and the end stop;
- and,
- the end stop is in contact with the resilient element.
A coolant control valve for an internal combustion engine, comprising:
- a housing including a surface;
- a rotary valve disposed within the housing, the rotary valve including:
- an axis of rotation;
- and,
- an end stop;
- and,
- a resilient element:
- fixedly connected to the surface of the housing;
- extending from the surface of the housing in a first axial direction parallel to the axis of rotation;
- and,
- including a portion furthest from the surface of the housing in the first axial direction, wherein:
- in a first circumferential position of the rotary valve about the axis of rotation, the end stop is:
- in contact with the resilient element;
- and,
- free of contact with the portion of the resilient element;
- and,
- in a second circumferential position of the rotary valve about the axis of rotation, the end stop is in contact with the portion of the resilient element.
A coolant control valve for an internal combustion engine, comprising:
- an axis of rotation;
- a housing including a surface facing in a first axial direction, parallel to the axis of rotation;
- a rotary valve disposed within the housing, the rotary valve including;
- a surface;
- and,
- an end stop:
- fixedly connected to the surface of the rotary valve;
- and,
- extending radially inwardly from the surface of the rotary valve;
- a resilient element:
- fixedly connected to the surface of the housing;
- and,
- including a portion extending furthest from the surface of the housing in the first axial direction, wherein:
- in a first circumferential position of the rotary valve about the axis of rotation, the end stop:
- is in contact with the resilient element;
- and,
- is free of contact with the portion of the resilient element;
- and,
- in a second circumferential position of the rotary valve about the axis of rotation, the end stop is in contact with the portion of the resilient element.
