摘要： A water heater that includes a tank, an electrical component, and an electrical circuit. The tank defines a water chamber and includes an outer surface. The electrical component is coupled to the outer surface of the tank and extends from the outer surface of the tank. The electrical circuit electrically connects the electrical component and provides electricity to the electrical component when the electrical circuit is closed and does not provide electricity to the electrical component when the electrical circuit is open. A door assembly is movable between an open position and a closed position, and the door assembly includes a connecting device mounted to the door assembly. The connecting device closes the electrical circuit when the door assembly is in the closed position and opens the electrical circuit when the door assembly is in the open position.

摘要： A pressure vessel (10) has partially telescoped upper and lower shells (12, 14), a diaphragm (20a) with a peripheral edge (26) trapped and sealed between the shells (12, 14), and compression structure (50, 52) on the inner side (44a) of the peripheral edge (26) of the diaphragm (20a) reducing the amount of diaphragm material requiring compression and also increasing the compression of the bulge (42) of the peripheral edge (26) of the diaphragm (20a) in the bulge (34) of the upper wall section (18) of the lower shell (14) to enhance the seal thereat. The compression structure includes one or more internal ribs (50, 52) on the inner side (44a) of the peripheral edge (26) of the diaphragm (20a) such that the inner cylindrical wall portion (38) of the lower wall section (16) of the upper shell (12) compresses the internal ribs (50, 52) and subjects the bulge (42) of the peripheral edge (26) of the diaphragm (20a) to a direct force to provide the noted increased compression of the bulge (42) of the peripheral edge (26) of the diaphragm (20a), and such that the inner cylindrical wall portion (38) of the lower wall section (16) of the upper shell (12) engages and compresses the first rib (50) to apply a radial outward force compressing the peripheral edge (26) of the diaphragm (44a) radially outwardly against a tapered wall portion (54) of the upper wall section (18) of the lower shell (14) which also compresses the peripheral edge (26) of the diaphragm (44a) downwardly into the widest radial area portion of the bulge (34) of the upper wall section (18) of the lower shell (14) to enhance the seal thereat, all while still maintaining ease of telescoped assembly of the shells (12, 14), and such that the radial force on the ribs (50, 52) from the inner cylindrical wall portion (38) of the lower wall section (16) of the upper shell (12) is allowed to spread the ribs (50, 52) axially into less compressed areas (74, 82) to enable the noted reduction in the amount of diaphragm material requiring compression.

摘要： A fill valve for a water heating system. An expansion tank is provided with a flexible diaphragm which divides the tank into a water chamber and a closed gas chamber. A fill valve assembly is mounted within an opening in the tank and includes a valve body having an axial passage and a radial passage connects the axial passage to a water inlet. One end of the axial passage communicates with the water chamber of the expansion tank, while the opposite end of the axial passage communicates with the water heating system. The central portion of the axial passage defines a valve seat and a hollow valve member is mounted for sliding movement in the axial passage, and the inner end of the valve member extends into the tank in position to be contacted by the diaphragm. Mounted on the valve member is an annular valve which is biased to engage the valve seat. A plurality of ports extends laterally of the valve member and provides communication between the inlet and the interior of the valve member. When the liquid in the water heating system expands, the diaphragm will be flexed inwardly causing the valve to be biased to a closed position to prevent water from entering through the inlet. When the volume of water in the heating system contracts, the diaphragm will flex outwardly moving the valve member within the valve body to open the valve and permit water to flow from the inlet to the heating system.

摘要： A pressure vessel (1) includes a pair of shells (2,3) which are suitably joined together. A flexible diaphragm (12) is disposed within the vessel and sealingly mounted to the vessel walls adjacent the joint. The lower shell wall (5) has a radially outwardly extending offset (17) and bulge (19) forming an interior groove (20) for receiving a projection (16) on the diaphragm. The bulge merges into an inwardly tapered wall (21) which in turn merges into an axial cylindrical wall (23) having a terminus edge (24). The upper shell wall (4) has a pair of spaced radially inwardly extending offsets (25,28). The upper (25) of said pair of offsets provides an abutment (26) receiving the terminus edge (24) of the lower shell. An axial cylindrical wall (29) between the pair of inward offsets press-fittingly engages the upper edge portion (23) of the lower shell. A further cylindrical wall (30) extends downwardly from the lower (28) of said pair of offsets and compressingly engages the diaphragm (12) so that it tends to ride down the inclined ramp-like tapered wall (21) and tightens into the groove (20) during assembly. The further cylindrical wall (30) merges into an inwardly tapered protective lip (32).

摘要： A rotor in which shaft portions are welded directly to the ends of a rotor stack by friction welding, which eliminates the need for a shaft hole in the rotor stack, thus providing a rotor in which each lamination has an unstamped, solid center, and the rotor has no other bores therein. As a result, no scrap is generated and motor efficiency is improved because the rotor has no bores therein. In addition, the amount of shaft material needed is also reduced because the shaft does not extend through the rotor stack.

摘要： A combination anode mount and hot water outlet for a water heater. The water heater includes a steel tank to contain water to be heated and has an upper head formed with an opening therein. An annular internally threaded spud is secured to the upper surface of the head with the axis of the spud being located eccentrically with respect to the axis of the head opening. An elongated body or support formed of an electrically insulating material, such as plastic, extends through the opening in the head and a cam shaped flange extends laterally from the upper end of the body and is disposed within the spud and is supported on the upper surface of the head. The body is formed with an outlet passage which communicates with the interior of the tank so that heated water in the tank can flow through the passage for discharge. An anode is secured to the lower end of the body and an electrical connector embedded in the body is connected to the anode and extends upwardly and is exposed at the cam flange. By rotating the body within the opening in the head, the cam will wedge against the threads of the spud to lock the body against rotation and provide a positive electrical connection between the electrical connector and the spud.

An annular internally threaded spud is welded to the upper surface of the head in alignment with the opening in the head. The anode mount and hot water outlet includes a tubular metal body having an upper threaded end which is threaded to the spud. A wall or closure extends transversely across the body intermediate the ends and divides the body into an upper chamber and a lower chamber. Ports are provided in the body and establish communication between the tank and the upper chamber and serve to conduct heated water from the tank. The upper end of an anode formed of a metal electro-negative to steel is mounted in the lower chamber of the body and the steel core wire of the anode is welded within a hole in the transverse wall. The tubular body can be coated with a corrosion resistant metal and the portions of the body exposed to water in the tank and also be provided with an outer plastic coating.
