The present invention relates to a control device for an automotive air conditioner, and in particular, a combination of a solenoid valve and a vacuum actuator that can control the throttle valve of the carburetor in a single body.

As is well known, the air conditioner installed in a vehicle increases the amount of cooling. In monitoring, it is proportional to the engine speed.

That is, if the engine is a high speed, the number of revolutions of the cooling compressor associated with this is followed at high speed, so that a large amount of cool air can be discharged in the vehicle, while the engine is low in cooling efficiency.

In general, the engine speed is changed according to the driving conditions, but the cooling of the room should be kept constant only in the adjusted state, for example, to increase the engine speed even when the vehicle is stopped, so that the cooling compressor operates normally. You must

Therefore, the apparatus for properly adjusting the throttle valve of the carburetor related to the operation of the engine according to the cooling state is a vacuum actuator and a solenoid valve, and is conventionally connected to the tube 40 as shown in FIG.

As a function, it is operated when the output of the air conditioner falls below the permitted level.

That is, when the solenoid 31 is coined by the signal, the core 34 is opened by the magnetic force of the coil 33 and the vacuum generated by the vaporizer 38 is immediately passed through the check valve 35 to the rubber sucker of the actuator 32. By sucking the 37 and towing the rod 36, the throttle valve 39 connected to the rod 36 was interlocked.

The conventional technique as described above exhibits the proper function of cooling management, but in the configuration, since the solenoid valve and the actuator are divided into separate structures, the following defects are inherent.

1. Since they are manufactured independently of each other, they become uneconomical factors such as material consumption rate and manufacturing process.

2. The space occupied area at the time of installation is big and it makes interference around.

3. The trouble of airtightness and installation of connecting tube is followed.

Therefore, the Applicant has completed the present invention after completing the structural improvement on the main purpose of making the function of the solenoid valve and the actuator satisfactory, but merging them into one body.

Now, a preferred configuration of the present invention will be described in detail with reference to the accompanying drawings.

Figure 1 is a perspective view showing a combination of the solenoid valve and the actuator according to the present invention shows an appearance that constitutes one body.

Its interior can be clearly seen in Figures 2 and 3, Figure 2 is a breakdown of the present invention, a part of the cut to show in detail and Figure 3 is a cross-sectional view of the assembled state.

A vacuum passage 2 is formed in the upper housing 1, and the cap 3 is attached to the lower portion thereof, and a cylindrical coil cabinet 5 including a coil 4 is embedded therein, and is firmly formed with a diaphragm 6. Sticks.

A cylindrical tube formed at the center of the coil cabinet 5 is inserted into the core 7 with the louver 7 'embedded therein with a spring 8, and a projection 9' at the center of the diaphragm 6 supporting the spring 7. From the "b" type aeration passage 9 and a vertical intake passage 10 are formed respectively.

When the housing 1 and the cap 3 are joined together, the plate-type rubber suction plate 11 is interposed and a spring 13 is elastically installed between the reinforcing plate 12 and the plate 6 grounded on the inner surface thereof. On the back, the fixing bracket 14 is coupled with the cap 3.

The fixing bracket 14 is screwed to the outer surface, and the bushing 14 'is coupled to the inner surface so that the rod 15 bound from the reinforcing plate 12 is discharged into the bushing 14' and then the length adjusting tube ( 16) is configured to be connected to the holder 17.

In the figure, reference numeral 18 denotes a vent, 19 denotes a power supply line, and 20 denotes a support plate.

The present invention configured as described above is to open and close the throttle valve by moving the holder 17 as a result of the operation state described in order as follows.

Cooling output deterioration signal → coil energization (4) (magnet) → core (7) forward → vacuum passage (2) opening → intake (10) → rubber sucker shrinkage (11) → rod (15) and holder (17) tow → The throttle valve is operated in the order of opening.

In other words, when the output drops, the current is turned on in response to this signal, and the magnetic force is advanced while opening the vacuum passage 2 in which the core 7 is elastically sealed by the magnetic force.

At this time, since a small amount of air is discharged through the vent 9 of the diaphragm 6, the obstacle to the movement of the core 7 can be eliminated.

When the core 7 opens the vacuum passage 2, the vacuum generated from the vaporizer of the engine is acted on the inside of the rubber suction plate 11 through the vacuum passage 2 and the intake passage 10, thereby providing a flexible high suction plate ( 11) is contracted by the intake force to follow the rod 15 coupled thereto.

Therefore, since the holder 17 connected to the rod 15 increases the amount of fuel supplied to the engine by opening the throttle valve, the number of revolutions of the engine is increased and the number of revolutions of the cooling compressor is also increased, so that the cooling operation is smoothly performed.

However, when the engine rotates at high speed, the coil 4 is disconnected by the signal, and the rubber sucker 11 including the core 7 is restored by the respective springs 8 and 13, and the vacuum passage 2 is It is closed so that the throttle valve is not operated.

In this operation, the play of the throttle valve can be adjusted by the length adjusting tube 16.

As described above, the series of operations meet the purpose of automatically increasing the rotation of the engine for optimum heating as in the prior art, but by achieving the equivalent function in the state in which the actuator and the solenoid valve are combined, In addition to reducing costs and simplifying the manufacturing process, cost reductions can be achieved, as well as simple installation and reduced space occupancy.
