FLUID COOLANT UNION TO PREVENT DRY OPERATION OF FIRST SEAL ASSEMBLY WHEN UNION IS OPERATED IN NON-PRESSURIZED STATUS

摘要

PURPOSE: A fluid coolant union is provided to use at least one inclined hermetic face among in a non-rotary and a rotary floating seal assemblies of the coolant union. CONSTITUTION: A fluid coolant union(10) contains a seal assembly(18) having a first seal member(20) and a second seal member(22). One circular hermetic face(25) by the rotary seal member and the non-rotary seal member has a smaller width than the other hermetic face(29) by processing as an inclined face. The coolant union contains a U-shaped circular secondary seal member having an inclined face to be inserted a square sectional reinforcing ring to sufficiently absorb the relative displacement of a floating seal assembly.
