Abstract: A throttle body assembly for a combustion engine includes a throttle body having a pressure chamber including a supply of liquid fuel, and a throttle bore with an inlet through which air is received. A throttle valve is carried by the throttle body with a valve head movable relative to the throttle bore. A metering valve is coupled to the throttle body, and has a valve element that is movable between open and closed positions. A boost venturi is located in the throttle bore and has an inner passage that is open at both ends to the throttle bore. The boost venturi has an opening through which fuel flows into the inner passage when the valve element is in the open position, wherein fuel flows from the pressure chamber to the metering valve under the force of gravity or under a pressure of less than 6 psi.

Abstract: A valve assembly includes a body and a push-to-connect fitting. The body includes an end segment that defines a fluid outlet and a connector portion. The connector portion includes an inner peripheral wall and an outer peripheral wall. The inner peripheral wall has a first exterior surface, and includes a first portion and a second portion. The first exterior surface has a first outer diameter in the first portion and a second outer diameter in the second portion that is greater than the first outer diameter such that a stepped profile is formed along the first exterior surface. The inner peripheral wall defines a fluid inlet. The outer peripheral wall extends from the inner peripheral wall and at least partly around the fluid inlet. The outer peripheral wall has a second exterior surface with a third outer diameter that is greater than the second outer diameter.

Abstract: A valve assembly includes a body having a fluid inlet disposed on a first end of the body and a fluid outlet disposed on a second end of the body in fluid connection with the fluid inlet. The valve assembly further includes a push-to-connect fitting which is integral to the body and configured to connect to an end of a pipe, a stem configured to seal the body in a first position and configured to allow fluid to flow from the fluid inlet of the body to the fluid outlet in a second position, and a connector surrounding at least part of the push-to-connect fitting. The body is configured to house a sealing ring. The push-to-connect fitting is configured to communicate the fluid inlet with the end of the pipe. The sealing ring secured by the push-to-connect fitting is configured to provide a seal between the fluid inlet and the end of the pipe.

Abstract: A valve assembly includes a body, a fitting, and a stopper assembly. The body has a first end and a second end. The body includes a connector portion positioned at the first end, a nozzle portion positioned at the second end, and an intermediate portion connecting the connector portion to the nozzle portion. The connector portion includes a peripheral wall having a crimped end that defines a fluid inlet. The nozzle portion defines a fluid outlet. The connector portion, the intermediate portion, and the nozzle portion cooperatively define a fluid flow path extending from the fluid inlet to the fluid outlet. The fitting is disposed within the peripheral wall. The fitting is held within the peripheral wall by the crimped end. The stopper assembly is coupled to the body along the intermediate portion. The stopper assembly is configured to facilitate selectively restricting a flow along the fluid flow path.

Abstract: A method of manufacturing a flat form from blended metallic powder including a major constituent by weight having a high melting point and a minor constituent by weiht having a substantially lower melting point includes selection of the powder to provide continuous and reproducible compacted flat forms. Powder is selected on the basis of compressibility and flowability. The selected powder is compacted to a flat green form and then liquid phase sintered. The flat form may be stacked to provide a flat article of a desired thickness which will result in a monolithic or composite cross section when subsequently sintered. Liquid phase sintering is carried out in a manner designed to avoid undesirable embrittlement and to provide a uniform microstructure in the fully consolidated article. The process is especially useful in the production of tungsten heavy alloy plate.
