Abstract
A removable sealing plug device for protecting the interior of a refrigerant compressor from dust, dirt, and corrosion during storage and/or transport of the compressor before it is assembled into a refrigerating system, including a plug element made of a rubber material and having a body portion adapted to being sealingly fitted in an inlet and/or outlet port of the compressor and a columnar head portion formed in an upper face of the body portion, and a base plate element having a through-bore in which the columnar head of the plug element is fitted with an interference fit, the base plate being secured to the outer circumference of the compressor, by using an existing threaded hole and a screw bolt, to hold the plug element between the base plate element and the outer circumference of the compressor. The plug element of the sealing plug device is provided with a handle portion extending laterally from the body portion thereof to permit the sealing plug device to be easily removed from the inlet port and/or outlet port of the compressor.
