A check device for an air conditioning system of an automobile and an air conditioner compressor includes a first path for containing coolant flowing therein. An air conditioner compressor, a condenser, an inflate valve and an evaporator are sequentially mounted to the first path to divided the first path. Two opposite ends of the first path respectively connected to a high-pressure outlet and a low-pressure inlet of the air conditioner compressor. Two pressure gauges are respectively mounted to the first path, one before the air conditioner compressor and the other after the air conditioner compressor relative to the flowing direction of the coolant in the first path for showing the difference of the pressure value of the coolant between passing before the air conditioner compressor and passing after the air conditioner compressor.

1. A check device for an air conditioning system of an air conditioner compressor, comprising:a first path including opposing first and second ends opposite, an air conditioner compressor, a condenser, an inflate valve and an evaporator sequentially mounted to the first path, the first path being divided into a plurality of high-pressure and several low-pressure sections, the first end and the second end of the first path respectively connected to a high-pressure outlet and a low-pressure inlet of the air conditioner compressor; a high-pressure gauge and a low-pressure gauge respectively mounted to the high-pressure outlet and the low-pressure inlet of the air conditioner compressor for showing the pressure valve; a first adjust valve mounted to the first path between the condenser and a drying device; and a second adjust valve mounted to the first path between the inflate valve and the evaporator, the first adjust valve and the second adjust valve being adjusted to make the pressure values from the high-pressure gauge and the low-pressure gauge correspond to the recorded pressure values to find a block in the first path. 2. The check device as claimed in claim 1 further comprising a third adjust valve mounted to the first path between the drying device and the inflate valve for simulating a block in the drying device, and the drying device mounted to the first path between the condenser and the inflate valve.3. The check device as claimed in claim 1 further comprising a coolant supplier connected to and communicating with the first path before the air conditioner compressor, an induce switch mounted to the first path for selectively opening the coolant supplier.4. The check device as claimed in claim 1 further comprising an oil-separator mounted to the first path between the air conditioner compressor and the condenser for collecting the oil in the first path from the air conditioner compressor.5. The check device as claimed in claim 4 further comprising a second path communicating with the first path, the second path including a first end, a middle section and a second end, the first end of the second path having two manifolds respectively communicating with the first path before the air conditioner compressor and communicating with the first path after the air conditioner compressor, an oil-container connected to and communicating with the middle section of the second path, a vacuum pump mounted to the second path between the first end and the middle section of the second path.6. The check device as claimed in claim 5 further comprising a filter mounted in the high-pressure outlet to prevent the impurities from entering the check device.7. The check device as claimed in claim 6 further comprising a manifold mounted to the first path near the low-pressure inlet of the air conditioner compressor and connected to the vacuum pump, whereby the vacuum pump with two check valves makes the pressure in the air conditioner compressor negative, and a pressure gauge mounted to the manifold.8. A check device for an air conditioning system of an air conditioner compressor, comprising;a first path, an air conditioner compressor, a condenser, an inflate valve and an evaporator sequentially mounted to the first path, the first path being divided into a plurality of high-pressure sections and several low-pressure sections, the first end and the second end of the first path respectively connected to a high-pressure outlet and a low-pressure inlet of the air conditioner compressor; two pressure gauges respectively mounted to the first path, one before the air conditioner compressor and the other after the air conditioner compressor relative to the flowing direction of the coolant in the first path for reading the difference of the pressure value of the coolant at a point before the air conditioner compressor and at a point after the air conditioner compressor; and whereby the operator can read the pressure values from the two gauges and compare with the previously set pressure values to determine whether the air conditioner compressor is in a right condition when the first path is in a normal condition and the air conditioner compressor is operating. 9. The check device as claimed in claim 8 further comprising an oil-separator mounted to the first path between the air conditioner compressor and the condenser for collecting the oil in the first path from the air conditioner compressor.10. The check device as claimed in claim 9 further comprising a second path communicating with the first path, the second path including a first end, a middle section and a second end, the first end of the second path having two manifolds respectively communicating with the first path before the air conditioner compressor and communicating with the first path after the air conditioner compressor, an oil-container connected to and communicating with the middle section of the second path, a vacuum pump mounted to the second path between the first end and the middle section of the second path.11. The check device as claimed in claim 10 further comprising a filter mounted in the high-pressure outlet to prevent the impurities from entering the check device.12. The check device as claimed in claim 11 further comprising a manifold mounted to the first path near the low-pressure inlet of the air conditioner and connected to the vacuum pump, whereby the vacuum pump with two check valves makes the pressure in the air conditioner compressor negative, and a pressure gauge mounted to the manifold.
