ABSTRACT:
In a body supporting another body via a land into which sealing gas is supplied via an in-coming gas groove or grooves for liquid sealing purpose and from which fluid is discharged through a fluid groove, one or more sets of out-going gas grooves are formed opening to the land in between the in-coming gas groove(s) and the fluid groove so that both undesirable mixing of the sealing gas with the fluid and accidental invasion of outside dust or the like into the arrangement is effectively prevented.
