ABSTRACT:
The flat sealing member of the device is forced against the end face of the mutually rotatable rollers by virtue of a bow-shaped projection having a triangular cross section and somewhat rounded off crest to provide a relatively linear contact. The above flat sealing member has a hollow interior space for a refrigerant and a lubricant to feed thereinto, both of them being then delivered to the zone of contact of the above projection and the end faces of the rollers. Such a system reduces wear on the rubber-coated roller surface and adds to the service durability of the whole unit.
