The horizontal rotary compressor according to the embodiment of the present invention is constructed as described above, and the compression action as described above is performed by the rotation of the crankshaft 7 as the motor 2 is driven. That is, the rotation of the crankshaft causes the centrifugal pump 13 to follow the rotation, and the centrifugal pump 13 causes the oil in the oil reservoir 1a to flow into the oil supply passage 12 through the oil supply pipe 14, and is supplied to each sliding part. When this occurs, a large amount of oil is scattered from the tip side of the centrifugal pump 13 due to the centrifugal force. However, the discharge hole 9 provided in the compression element 6 is arranged in the front head 4, and the centrifugal pump 13 is connected to the opening 12a of the oil supply passage 12 which opens at the shaft end of the crankshaft 7 on the compression element 6 side. The outlet path of the discharged gas discharged from the compression element 6 and reaching the discharge pipe 11 does not pass through the installation part of the centrifugal pump 13, so that the oil discharged from the centrifugal pump 13 directly flows into the compression pipe 11. Since mixing with the gas refrigerant discharged from the element 6 can be minimized, and the oil level in the oil reservoir 1a along the outflow path is not disturbed by the oil discharged from the centrifugal pump 13, It is possible to significantly suppress oil from becoming a mist and mixing with the gas refrigerant. Therefore, there is no possibility that the scattered oil will enter the gas refrigerant and flow out of the machine from the external discharge pipe 11 as it is.

(Effect of the invention) As explained above, in the horizontal rotary compressor according to the invention, a discharge hole is provided in the front head of the compression element, and a discharge hole is provided in the front head of the compression element, and a discharge hole is provided from the bearing tube of the front head to the crankshaft that connects the compression element and the motor. An oil supply passage extending along the length of the crankshaft and opening at the shaft end on the compression element side is formed, a centrifugal pump is connected to the opening of the oil supply passage, and a bearing of the front head is connected to the oil supply passage. Since an oil supply pipe communicating the oil supply passage and the oil reservoir is connected to the cylinder, as the centrifugal pump rotates, the oil discharged from the opening of the centrifugal pump is mixed with the gas discharged from the compression element. It is possible to prevent the oil from mixing with the refrigerant, and it is also possible to prevent the oil level in the oil reservoir from being disturbed by the centrifugal pump and the oil becoming mist and mixing with the gas refrigerant, so that the mixed oil can be discharged to the outside. As a result, it has become possible to significantly suppress the outflow from the pipe 11 to the outside of the machine.
