    摘要: THIS INVENTION COMPRISES A SELF-CONTAINED UNITARY PACKING DEVICE WHICH MAY BE INTERCHANGEABLE WITH A ROTARY MECHANICAL SEAL. THE PACKING DEVICE COMPRISES A CUP-SHAPED METAL CONTAINER IN WHICH IS DISPOSED ONE OR MORE RINGS OF PACKING TOGETHER WITH A SPRING WHICH EXERTS AN AXIAL FORCE UPON THE PACKING IN THE MANNER OF A PACKING GLAND. THE CONTAINER IS PRESSED INTO A CUP-SHAPED RUBBER SEAT IN A RECESS IN THE HOUSING TO SEAL IT IN THE HOUSING AND TO HOLD IT AGAINST ROTATION WITH A SHAFT PASSING THROUGH. THE SPRING HOLDS THE PACKING RINGS AGAINST THE CONTAINER AND COMPRESSES THE RINGS AGAINST THE SHAFT. THE CUP-SHAPED RUBBER SEAT MAY BE USED ALTERNATIVELY TO HOLD A SEALING WASHER OF A ROTARY MECHANICAL SEAL ADAPTED TO FIT INTO THE SAME SPACE.
