<p>PROBLEM TO BE SOLVED: To facilitate inspecting leakage of refrigerant gas in a compressor mounted in a vehicle.SOLUTION: A gas collection groove 22 and a connection channel 23 are provided in an end surface 5 of a pipe joint portion 4 of a compressor 1. One end of the gas collection groove 22 is open to an annular groove 31 of a discharge hole 7 and the other end extends to an outer circumferential edge of the pipe joint portion 4. One end of the connection channel 23 is open to an annular groove 30 of an intake hole 6 and the other end is open to the annular groove 31 of the discharge hole 7. Refrigerant gas leaking from the intake hole 6 flows to the connection channel 23 from the annular groove 30 of the intake hole 6 to be collected therein, flows into the annular groove 31 of the discharge hole 7 from the connection channel 23, then flows to the gas collection groove 22 to be collected therein, and is discharged to outside. The refrigerant gas leaking from the discharge hole 7 flows to the gas collection groove 22 from the annular groove 31 of the discharge hole 7 to be collected therein and is discharged to outside. It, therefore, suffices to set a leak tester to approach only one portion at an open position of the gas collection groove 22 and the leak tester can easily detect leakage of the refrigerant gas.</p> |
