摘要： Graphite-containing brass alloy billets having less than 0.25 wt. % lead and a method of manufacturing relating thereto are provided. The method includes forming a brass powder and mixing the brass powder with graphite and one or more binders. The brass powder contains copper and zinc and may be formed using water atomization. The brass-powder mixture is compacted to form an initial billet. The initial billet may be subjected to one or more heating treatments. A first heating treatment may be used to remove the one or more binders. An optional second heating treatment may be used to deoxidize the binder-free billet. An optional third heating treatment that includes applying a pressure may be used to densify the binder-free billet. A third heating treatment may sinter the compact to form the workable graphite-containing brass alloy billet.

摘要： A refrigerant powered actuated ball valve for use in the fluid circuit of a refrigeration or air conditioning system which can be remotely controlled by a low amperage control signal is disclosed. The actuated ball valve harnesses the pressurized refrigerant from the fluid circuit in which it is installed as the primary power medium to actuate the valve. The valve includes actuation means with a manifold having an inlet port which is in constant fluid communication with a high-pressure side of the fluid circuit. Pressurized refrigerant supplied to the manifold is branched to a series of fluid channels running through the manifold. Exhaust port operators are mounted in conjunction with the manifold to connect the actuation means to the low-pressure side of the fluid circuit and to direct the flow of pressurized refrigerant to either an exhaust port or the manifold. A reciprocal member disposed within the manifold engages a pinion such that a linear displacement of the reciprocal member causes a corresponding angular displacement of the pinion member. Cycling of the ball valve between an opened position and a closed position is achieved when the pressurized refrigerant is applied to the reciprocal member thereby causing a stem operator on the ball valve to rotate.

摘要： A valve, such as a compressor or line service valve, for use in refrigeration or air conditioning fluid circuits having an improved flow for improved energy efficiency is disclosed. The valve incorporates a rotary ball member with a 90.degree. fluid passage diameter that is equal to or greater than the diameter of the fluid line that it services. Rotation of a primary actuator stem rotates the ball member to open and close the valve. An annular ball seal provides a seat against which the ball may be positively sealed. A secondary stem is aligned on an alternate axis from the primary stem that is preferably collinear with a fluid line. The secondary stem effectuates a positive engagement between the rotary ball member and the ball seal. A plunger cooperates with locator indentations and a groove in the rotary ball member to center the ball within the valve and align its fluid passage with fluid line connectors. Locator indentations also ensure that the rotary ball member is properly oriented when in either the opened or closed positions. When the secondary stem is engaged, it effectuates a positive shut-off force to seal the ball member against the ball seal.

摘要： A fitting for sealingly and fixedly coupling to a component that includes a body having a first insertion end that defines a first end face and a cavity. The cavity has an interior surface. A first seal is adapted to engage a first component when the first component is inserted through the insertion end and into the cavity. The seal extends into the cavity from the interior surface of the cavity. A band of sealant is located about a perimeter of the cavity. The band of sealant is adapted to seal the interior surface and the first component. The body is crimped around the first component to secure the fitting to the first component and seal the interior surface to the first component.

摘要： A seal member for sealingly securing a first and a second pipe at a crimp connection, the seal member including a ring-shaped body having an outer diameter and an inner diameter. A plurality of protrusions are formed on the ring-shaped body and extend radially outwardly from the outer diameter. The ring-shaped body permits fluid to pass around adjacent protrusions prior to attaining the crimp connection and inhibits fluid from passing therearound subsequent to attaining the crimp connection.
