Rotary valve assembly for coolant control valve and coolant control valve with rotary valve assembly

A coolant control valve, comprising:

• a housing with a first port and a second port;
• a secondary rotary valve:
• disposed within the housing;
• and,
• formed by a single-piece secondary body;
• and,
• a primary rotary valve:
• including at least a portion nested within the secondary rotary valve;
• including a primary body;
• and,
• defining a primary opening, wherein:
• the secondary body defines a secondary opening;
• and,
• the primary rotary valve and the secondary rotary valve are rotatable by at least one actuator and around an axis of rotation, the secondary body is discontinuous in a circumferential direction around an entirety of the axis of rotation, wherein the primary rotary valve and the secondary rotary valve are rotatable to:
• a zero flow configuration in which the primary body blocks the first port and the secondary body blocks the second port;
• or,
• a first flow configuration in which the primary opening overlaps at least a portion of the first port and none of the second body overlaps the second port;
• or,
• a second flow configuration in which the primary opening overlaps an entirety of the first port and the secondary body blocks only a portion of the second port;
• or,
• a third flow configuration in which the primary body blocks the first port and the secondary body blocks only a portion of the second port.
