Abstract: A combination regulator valve for conveying fluid is disclosed. The valve comprises a bonnet, a body, a flexible diaphragm, a first spring, and a spindle unit. The spindle unit comprises a pin, a first seat disc, and a seat screw. The bonnet is secured to the body. The flexible diaphragm is compressed between the bonnet and the body. The first spring is disposed in the bonnet. The spindle unit is disposed in the body. The first seat disc is disposed between the pin and the diaphragm. The first seat disc and the pin define a first void. The first spring biases the diaphragm toward the first seat disc. The seat screw is engaged with the body and is slidably engaged with the pin. The seat screw and the pin define a fluid passage in fluid communication with the first void.

Abstract: An improved crimp joint for joining components of gas or fluid distribution systems is disclosed. The joint is particularly suited for use with components made from low ductility materials including die cast metals. The joint comprises a flange formed by a first joined component and a second component that defines a second mating surface and a lip that is configured to closely surround at least a portion of the flange when the flange is positioned adjacent to the second mating surface. The joint is formed by deforming the lip to overlie the flange, capturing the flange between the deformed lip and the second mating surface. The flange includes a bead formed near the periphery of the flange on a surface against which the lip is deformed to abut to form the crimp joint. The bead is sized to deform and engage the lip thereby increasing the strength of the crimp joint.
