Optional feature 600 (Fig. 1) outside motor.
Preferably due to the characteristic of valve group 10 as described above, in detent position, valve group keeps first-class P1 and the
Second-rate P2 separates and therefore keeps corresponding main flow PP1 and PP2 to divide out.
Creatively, valve group involved in the present invention is positioned in the cooling system of vehicle and relevant motor, thus permits
Permitted in time and reliably controlled the passing through of two streams separated of coolant.
Advantageously, two liquid streams maintain separately from each other until arriving valve group.
Advantageously, moreover, the stream of coolant is only mixed with each other in the downstream of closure elements.
According to the aspect that another is favourable, valve group, specifically, this closure elements when the closure elements of valve group is in detent position
Self poisoning is on pipeline mouth thus the stream being blocked in input passes through；Therefore closure elements is made to keep the power needed for closing to need
Correct to stand the active force raw by two miscarriages；Advantageously, this is all proved to be the easiest and this side
Formula achieves airtight closing thus keeps two liquid streams to be completely separated from, it is to avoid reveal or similar problem.
According to another favourable aspect, by closure elements being directly positioned on mouth it is achieved that hinder and
Without sealing surfaces.
Advantageously, valve group is suitable to use undersized pipe operations, is particularly suitable for mobile limited stream.
Advantageously, moreover, by being suitable to the control device along axis translation, it is possible to realize in a particularly simple manner closing
The movement of element.
According to the aspect that another is favourable, the geometry of valve group is extremely simple.
According to the aspect that another is favourable, valve group is proved to be size that is extremely compact and that have reduction, and therefore
It is easily inserted vehicle interior.Advantageously, it practice, the space that valve group only occupies is owing to controlling the space needed for the size of element
And for the mobile space controlled needed for element.
Advantageously, in a cooling system, due to valve group, can cool down the inblock cylinder of heat absorption motor and other parts or they
Cooling be controlled；Especially, the internal part that heat absorption motor is other can be cooled down, maybe can cool down the outside that heat absorption motor is other
Parts.
