Description
BACKGROUND OF THE
Generally, the automobile is provided with an air conditioner for cooling and heating. The air conditioner includes a compressor that compresses low-temperature and low-pressure refrigerant introduced from an evaporator into high-temperature and high-pressure refrigerant and sends it to a condenser. In such a compressor, a swash plate type compressor is generally used.
When the compressor is driven, the temperature of the evaporator is lowered. When the compressor is stopped, the temperature of the evaporator is increased.
In the swash plate type compressor, a swash plate having an inclination angle of a predetermined angle is provided on a rotating shaft provided in a compressor, and a piston in a cylinder bore connected to the swash plate reciprocates in conjunction with rotation of the rotating shaft to compress the refrigerant.
Such swash plate type compressors include a fixed capacity type and a variable capacity type. Generally, the discharge capacity of the variable displacement swash plate type compressor is achieved by controlling the inclination angle of the swash plate. When the cooling load is increased, the inclination angle of the swash plate is increased and when the cooling load is decreased, the inclination angle of the swash plate is controlled to be decreased. For reference, the angle of inclination of the swash plate means the angle formed by the plane perpendicular to the drive shaft and the swash plate.

It is an object of the present invention to provide a compressor which can change the discharging direction of a refrigerant to a direction desired by a user in a pressure relief valve operation while minimizing cost consumption.
The compressor according to the present invention as described above comprises a housing constituting an outer appearance of the compressor, a compression mechanism provided in the housing for sucking and compressing the refrigerant, a discharge part formed in the housing and discharging refrigerant compressed in the compression mechanism part A pressure relief valve provided at one side of the housing and having an outlet for sensing the pressure inside the discharge path and discharging the refrigerant to the outside when the pressure is equal to or higher than a predetermined pressure, a passage communicating with the discharge port, A discharge member provided at an outer end of the pressure relief valve and a fixing means for fixing the discharge member to the pressure relief valve, And the direction is variable.
According to an embodiment of the present invention, the fixing member includes a body portion for pressing the discharge member toward the pressure relief valve, a fixing member extending downward from the body portion and having a latching protrusion hooked to the latching groove of the pressure relief valve, And a latching groove formed on a side surface of the pressure relief valve to hook the latching protrusion.
The discharge member may include a main body having a passage formed at a predetermined depth in a discharge direction of the refrigerant, and an opening communicating with the passage to discharge the refrigerant to the outside, and may be formed of an elastic material.

According to the compressor of the present invention, it is possible to easily change the outlet of the pressure relief valve in a desired direction by the customer while sharing the existing mold and at low cost.
And the discharge direction of the refrigerant can be adjusted irrespective of the direction in which the pressure relief valve is assembled.
