    摘要： A fitting to be secured on pipes can be used with a number of distinct pipe materials and types. The fitting includes a nut receiving a Belleville spring washer. As the nut is tightened on threads on an end fitting, it forces the Belleville spring washer away from a relaxed position. This causes a radially inner portion of said spring washer to dig into an outer surface of the pipe, locking the Belleville spring washer, and hence the nut, on the pipe. The deformation of the washer also forces a ring against an inner seal, deforming the seal against the pipe, the nut, and the end fitting. In a second embodiment, a second washer is also deformed. The present invention provides a simple and universal method of attaching pipes to end fittings.

    摘要： A fluid connection for connecting a tubing, such as a gas tubing for a hot water tank burner, to a metal fitting includes a deformed outer portion of the fitting. In particular, a recess is defined between radially inner and outer portions of the fitting, and the tubing is inserted into that recess. The inner portion of the fitting extends into an inner bore of the tubing to provide support at the inner bore. The outer portion of the fitting is then deformed radially inwardly to secure the tube to the fitting.

    摘要： A gas supply coupling is disposed within and extends through an opening of a combustion chamber for a water heater. The coupling including a fitting which is a relatively inexpensive stamped component. A stepped tubular connection extends from a plate and includes a first portion having a first diameter which necks down to a second portion having a second diameter less than the first diameter. The stepped tubular connection receives a gas supply tube into the first portion and a gas supply line over the second portion. The tubes are braised to the stepped connection. Other gas supply couplings include a machined fitting and a direct connection between a gas supply tube and a gas supply line in which the gas supply tube itself provides for both the seal to the shield and the connection to the gas supply line.

    摘要： A fill valve for controlling the filling of a fluid reservoir such as a cistern. The valve minimizes the time needed to fill the reservoir by maintaining maximum fluid flow through the valve until instantaneous shut off of the fill valve once the reservoir is filled. The fill valve includes a reciprocating valve head carried on a valve stem connected to a float arm for determining the fluid level within the reservoir. The valve head is disposed within an enclosure having grooves for conducting fluid flow past the valve head to create a back pressure behind the valve head. The valve stem seals a passageway through the valve head which operates as a pilot valve during opening and closing of the valve.
