The oil-valve assembly of the air conditioner compressor of a vehicle according to the present invention includes a housing which has a discharge path which is connected to one end and the other end, a moving part which is arranged in one side of the discharge path and moves along the discharge path by the pressure difference of the one end and the other end of the discharge path, and a support part which is arranged in the other side of the discharge path. The inner surface of one side of the discharge path has a contraction part which protrudes from the center part of the discharge part. The moving part includes a core which touches contraction pat and closes the discharge path, and sleeves which are extended from the core to the other direction of the discharge path. The support part includes a guide which is inserted into the sleeves and guides the moving direction of the core, a guide support part which is extended from the guide and touches the inner surface of the discharge path, and an elastic body which is arranged between the guide and the sleeve. The oil-valve assembly of the air conditioner compressor of a vehicle according to the present invention increases a contact area between the core and the discharge path, and moves the core in a direction which is approximately vertical to the discharge path, thereby reliably opening/closing the discharge path. The sleeve is formed in order to apply an inverse pressure to the core, thereby allowing the core to effectively close the discharge path. |
