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 suitable for 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 having a through-hole in which the columnar head of the plug element is press-fitted, the through-hole of the base plate being provided with sawtooth-like projections to non-removably hold the columnar portion of the plug element and secure it to the outer portion 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 and the base plate of the sealing plug device are concurrently removed from the inlet port and/or outlet port of the compressor due to a tight engagement of the plug element and the base plate provided by the sawtooth-like projections.
