Fig. 2 discloses the further details about first embodiment now with section view.Because of two model selections
Valve 9,10 is identical in terms of its Design and Features, therefore herein only with reference to the details of first mode selector valve 9.Fig. 2 is retouched
The state drawn is an off.First mode selector valve 9 and second mode selector valve 10 are in completely closed state as a result,.
Therefore, do not occur fluid stream between discharge port 4 and evaporator port 6 or between inhalation port 5 and evaporator port 6.The
One model selection valve 9 is solenoid valve.Therefore, which includes solenoid 11a.Solenoid 11a can be by benefit
It is screwed to the power supply of the shell of first mode selector valve 9 and motivates.When solenoid 11a is motivated, valve components are assisted
12a will be pulled up on the contrary with the bias force of first biasing element 13a (coil spring).Assist valve components 12a by main valve member
Part 14a and the second biasing element 15a (coil spring) are radially around second biasing element is arranged to make main valve element
14a is biased in open position.In addition, main valve element 14a includes auxiliary valve seat 16a, which includes longitudinal nozzle.Such as
It can be seen that, under the closed state of first mode selector valve 9, nozzle is extended to by the aperture of main valve seat 17a by providing
In inner cavity provided by the cylindrical wall of main valve seat 17a.It is opened in step first as a result, solenoid 11a is motivated, in this way
So that auxiliary valve components 12a moves away the auxiliary valve seat 16a provided by main valve element 14a.Pass through auxiliary valve seat 16a as a result,
Relatively small fluid stream be possibly realized, and the second biasing element 15a become tensioning main valve element 14a is pushed away to generate
The dynamic power for leaving main valve seat 17a.However, being preset to by the bias force that the second biasing element 15a is generated so that the bias force is small
In the bias force generated by the pressure drop in main valve element, until establishing the scheduled reduced pressure drop on main valve element 14a.?
On this time point, the pressure drop on main valve element 14a sufficiently reduces and makes main valve element 14a pushing off main valve seat
Thus 17a executes second and opens step.Because the internal diameter in the aperture of main valve seat 17a is 8mm, it is greater than the hole of auxiliary valve seat 16a
The internal diameter of mouth, therefore the fluid stream in the second unlatching step is than only having the first unlatching step of the aperture of auxiliary valve seat 16a unlatching
In fluid stream it is much bigger.

Continue 500ms at 2.2A and provides the peaking power of 50W for the solenoid 11a of first mode selector valve 9.However, instead of 24V
DC power supply, can be used can supply enough peaking powers so that dynamic auxiliary valve components 12a any power supply.As shown in Figure 3a,
First open step in, be arranged in auxiliary valve components 12a front end on shoulder be arranged to and auxiliary valve seat 16a phase
The second biasing element 15a is compressed between the surface of anti-main valve element 14a.In this state, by the second biasing member
The power that part 15a is provided still is not large enough to overcome power caused by the pressure drop of main valve element 14a.When since fluid is across auxiliary
When helping the aperture of valve components 16a and reducing pressure drop, after establishing scheduled reduced pressure drop, by the second biasing element
The power that 15a is generated is by strong to being enough to overcome by the power of pressure drop generation.Then main valve element 14a will be lifted from main valve seat 17a, such as
What Fig. 3 b described.
Fig. 3 b then shows the heating mode under full effect.Make first segment since auxiliary valve is in the open position when
When flowing the pressure drop reduction on valve 9, main valve element 14a is lifted from main valve seat 17a completely.Therefore, make main valve element 14a inclined
It sets and leaves the second biasing element 15a of main valve seat 17a and produce sufficiently strong power so that main valve element 14a moves to open position
It sets.In order to make that valve components 12a is assisted to be maintained in open position, the holding electric power supplied from power supply to solenoid 11a is sufficient
, peaking power, which is greater than, keeps electric power.In the embodiment depicted, if having selected heating mode, electric power is kept to be
2.5W, be applied with such as 60 seconds or longer time.After by closing the deactivated heating mode of first mode selector valve 9, the
One model selection valve 9 returns to the state of Fig. 2 description.

500ms and provide the peaking power of 50W for the solenoid 11b of second mode selector valve 10.Being connected by screw to makes power attachment
To second mode selector valve 10, as shown in fig. 4 a.However, can be used can supply enough peak value electricity instead of 24V DC power supply
Any power supply of power.Auxiliary valve components 12b is lifted from auxiliary valve seat 16b, and permission fluid flows to suction from evaporator port 6 in this way
Inbound port 5.Refrigerant can be from being fluidly coupled to the conditioner of evaporator port, 2 be transferred to across valve arrangement as a result,
Inhalation port 5 simultaneously enters suction line 8.
Fig. 4 b shows the refrigeration mode under full effect.When the pressure difference of second mode selector valve 10 is due to auxiliary valve member
When part 12b is in the open position and reduces, main valve element 14b is lifted from main valve seat 17b completely.Therefore, make main valve first
The second biasing element 15b that part 14b is biased away from main valve seat 17b produces sufficiently strong power so that main valve element 14b is moved to
Open position.It is sufficient, peak by the holding electric power that power supply is supplied to make that valve components 12b is assisted to be maintained in open position
It is worth electric power and is greater than holding electric power.In the present embodiment, similar to first mode selector valve 9, keeping electric power is 2.5W.If selection
