Abstract: An encapsulated magnet assembly comprises a non-metallic housing and a magnet disposed within a housing magnet chamber. A housing end cap is fuse bonded to the housing to encapsulate the magnet therein and form an air and fluid-tight seal with the housing. An insulating spacer is interposed between an exposed surface of the magnet and the end cap before assembly and fuse bonding, and is formed from a thermally insulating material to prevent the transmission of thermal energy to the magnet during the fuse bonding process. The insulating spacer serves to protect the magnet from unwanted thermally induced magnetic field losses. The housing also includes one or more projections that extend into the magnet chamber and that cooperate with complementary grooves in the magnet to prevent the magnet from rotating within the chamber.

Abstract: A valve assembly comprises a valve body and at least one valve seat is disposed within the valve body. A groove is disposed therein concentrically around the valve seat. A poppet assembly is disposed within the valve body and comprises an imperforate valve stem and a valve plug at an end of the valve stem. For three-way flow, the valve body includes two valve seats, and a valve plug at each valve stem end. A cap is attached to an end of the valve body top and a first flexible imperforate diaphragm is disposed within the cap. A second flexible imperforate diaphragm is disposed within the valve body bctwccn thc poppet assembly and the first diaphragm, and forms a leak-tight seal with the valve body. A base is attached to an opposite end of the valve body. A third flexible imperforate diaphragm is disposed in the valve body between the poppet assembly and the base, and forms a leak-tight seal with the valve body. A spring means is disposed between the base and the third diaphragm for imposing a biasing force onto the poppet assembly. A containment body is used to encapsulate the spring means and isolate it from any liquid that leaks past the third diaphragm.
