ABSTRACT:
A sealing plug has a stem portion inserted into an inlet of the compressor and contacted with a valve body of a check valve for forcing the check valve from closed position to maintain the check valve at open position. The sealing plug is also provided with a seal body for establishing a fluid tight seal at the sealing position. The seal body can be shifted from the sealing position to gas discharge position with maintaining the stem portion contacting the valve body of the check valve to keep the latter open. At the gas discharge position, the sealing plug permits the pressurized gas in the compressor to be discharged for lowering the internal gas pressure.
