AI Technical Summary
The existing multi-way valve experiences a rapid increase in flow rate during initial rotation, causing a momentary flow surge in the module and preventing a smooth transition in vehicle operating conditions.
A high-precision proportional multi-way valve for flow control is designed. By forming protrusions on the inner walls of the first and second valve passages of the valve core, the flow rate of the fluid at the initial rotation is controlled by adjusting the gap of the protrusions, thereby reducing instantaneous flow shock.
It reduces flow shock during initial rotation, ensuring a smooth transition of vehicle body operating conditions, and has good applicability and scalability.

Abstract
Claims
1. A high-precision proportional multi-way valve for controlling flow rate, comprising a valve housing (1) and a valve core (3) installed within the valve housing (1), wherein the valve core (3) is driven by an actuator to rotate relative to the valve housing (1), characterized in that, Multiple valve ports (2) are provided on the valve housing (1); The valve core (3) has a main channel (4) in the middle. The valve core (3) has valve channels (5) that are connected to the valve port (2) in the same direction around its end face. At least one valve channel (5) is connected to the main channel (4). The valve port (2) and valve channel (5) are connected by rotating the valve core (3).
2. The proportional multi-way valve of claim 1, wherein: The valve passage (5) includes at least a first valve passage (6) and a second valve passage (7), one of which is connected to the main channel (4) and the other is not connected to the main channel (4).
3. The proportional multi-way valve of claim 2, wherein: At least one valve wall extension protrusion (8) in the first valve passage (6) and the second valve passage (7) has a gap (9) between the protrusion (8) and the adjacent valve wall.
4. The proportional multi-way valve of claim 3, wherein: Adjust the gap (9) according to the transition undulation of the protrusion (8).
