摘要： A fluid supply system for a machine such as an internal combustion engine includes a shutoff valve having an electrical actuator that includes a solenoid subassembly, and a stabilizer for the electrical valve actuator. The stabilizer includes a fitting structured to couple the shutoff valve to adjacent hardware in the fluid supply system, and a strongarm extending between the fitting and the solenoid assembly and clamped to the solenoid subassembly. A vibration-damping reinforced grommet may be clamped between the solenoid subassembly and the clamp.

摘要： A throttle valve for a centrifugal compressor includes a body having a central passage and one or more diverter flow paths. The central passage is formed by an inner surface of the body, each diverter flow path has an inlet and an outlet, and the one or more diverter flow paths are configured to induce a swirl within a fluid flow through the central passage while a portion of the fluid flow passes through the one or more diverter flow paths. The throttle valve also includes at least one blade disposed within the central passage. The at least one blade is configured to direct the portion of the fluid flow to the inlets of the one or more diverter flow paths while the at least one blade is in a partially open position.

摘要： A system for gas extraction is provided with a flap valve coupled to a bore with a pivot axis offset from an axis of the bore. The valve includes a higher mass on a shorter side of the pivot axis. A valve surface on the shorter side is inclined above a horizontal plane when the valve closes. The valve opens during liquid and gas flow to extract gas from the flow. As liquid flows over the valve, the valve is forced to close. The center of gravity of the valve relative to the offset pivot point ensures that the valve remains closed during liquid flow. As gas flows over the valve, closing forces are reduced and under internal vacuum, the mass distribution about the offset pivot axis allows the flap of the valve to tilt; opening the valve and allowing gas to enter the bore.

摘要： A valve assembly includes a valve body that defines an internal flow passageway between an inlet and an outlet, and a valve seat disposed in the valve body with a sealing surface perpendicular to the flow passageway. The valve assembly further includes a clapper pivotally correlated to the valve seat having a closed configuration extending across the valve seat configured to substantially close off the flow passageway, and an open configuration configured to substantially allow fluid flow in the flow passageway from the inlet to the outlet through the valve body. An annular valve seat seal is disposed within an annular groove formed in a surface of the valve seat, where the annular valve seat seal is disposed at an interface between the valve seat and the clapper when the clapper is in the closed configuration.

摘要： The invention relates to a valve assembly (100) for a multi-scroll turbine (10) for controlling an overflow of exhaust gases between a first spiral (36) and a second spiral (38) and for controlling a bypass opening (50). The valve assembly 100 comprises a lever (110) and a valve closing element (120) which is operatively connected to the lever (110). Furthermore, the valve assembly (100) comprises a spring element (130) which is designed to pre-bias the valve closing element (120) the against lever (110).

摘要： Cleanout conduit valve installations may include at least one cleanout housing having a cleanout housing interior and configured for placement in the cleanout conduit hole with the at least one cleanout conduit extending into the cleanout housing interior. A cleanout housing opening may overlie the cleanout housing interior. An openable cleanout housing door may be disposed in the cleanout housing opening. At least one cleanout conduit valve assembly may be configured to be disposed in fluid communication with the at least one cleanout conduit in the cleanout housing interior of the at least one cleanout housing. The at least one cleanout conduit valve assembly may include a valve housing configured for mounting on the at least one cleanout conduit. A valve mount may be carried by the valve housing. A valve may include a valve arm pivotally carried by the valve mount. A valve stop may extend from the valve arm. A valve body may be carried by the valve arm. The valve body may have a sealing surface. The valve may be positional between a closed valve position configured to seal the valve housing and a full open valve position configured to unseal the valve housing. The valve stop may engage the valve body in the full open valve position.

摘要： A valve assembly for use with a container such as a fuel tank. Embodiments of the assembly include an inlet and outlet provided on separate sides of the central axis of a housing, the housing being connected to a central conduit located in a container. The valve assembly includes inlet and outlet valves which allow the venting of air during filling and the intake of air as fuel is consumed. The valve assembly is arranged so that air flows through a less torturous path compared to known prior art, enabling a high rate of filling to be achieved.
