Embodiment Construction

[0016] Referring to the drawings and initially to FIG. 1, a check device for an air conditioning system of an automobile and an air conditioner compressor in accordance with the present invention comprises a first path (10) has two opposite end respectively connected to a high-pressure outlet (111) and a low-pressure inlet (112) of an air conditioner compressor (11). A condenser (12), an inflate valve (13) and an evaporator (14) are sequentially mounted to the first path (10). The first path (10) is provided for coolant to circulate and form an interaction of air-phase and liquid-phase in the first path (10). A high-pressure gauge (15) and a low-pressure gauge (16) are respectively mounted on the high-pressure outlet (111) and the low-pressure inlet (112) of the air conditioner compressor (11) for showing the pressure value. A first valve (17) is mounted to the first path (10) between the high-pressure outlet (111) and the high-pressure gauge (15), and a second valve (18) is mounted...

Abstract

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.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a check device, and more particularly to a check device for an air conditioning system of an automobile and an air conditioner compressor. [0003] 2. Description of Related Art [0004] As usual, the air conditioning system of an automobile comprises a closed coolant path for containing the coolant circuitously circulated in the coolant path. An air conditioner compressor, a condenser, a inflate valve and an evaporator sequentially disposed on the closed coolant path. A drying device is further connected to the condenser. In operating, the coolant executes a heat exchange in the evaporator and a fan blows the cool air into the automobile. The above air conditioning system may lose its cooling effect due to a block or leaking coolant. [0005] According to the block of the coolant path, the reasons are the path containing too much water and oil, or the element of the air conditioning syste...
