  • Patent number: 6708959
    Abstract: A carburetor with a valve assembly having a plastic cam body connected to a plastic shaft which extends into the carburetor body and a valve head press-fit into a slot formed through the plastic shaft. Desirably, the valve assembly eliminates the use of threaded fasteners and the need to swage or otherwise deform any of the components to connect them together. Desirably, the shaft and cam body are constructed and arranged to prevent relative rotation between them. This permits accurate location of the cam body on the shaft and facilitates calibration of the throttle valve assembly between its idle and wide open throttle positions. Further, the characteristics of the throttle valve assembly can be changed by simply providing a cam body having a different shape or construction with the shaft and/or valve disc being the same for a wide range of carburetors.

  • Patent number: 6688585
    Abstract: A carburetor for a scavenged two-stroke internal combustion engine has an enriched fuel-and-air mixing passage extending through a housing of the carburetor. Engaged to the housing is a body of an air flow modular assembly which carries a primary air flow passage which houses a butterfly-type control valve therein. The throttle valve of the fuel-and-air mixing passage is mechanically linked or cammed to the control valve of the air flow passage so that opening of the throttle valve soon after opens the control valve allowing additional air to enter and provide a leaner fuel-and-air ratio in the combustion chamber of the engine when running under load. The air flow modular assembly has a sealing-and-bearing assembly which eliminates air leakage from the surrounding environment along the shaft of the control valve and into the primary air flow passage. The sealing-and-bearing assembly has a bushing which inserts into a counter bore of a cylindrical bore which receives the rotating shaft of the control valve.

  • Patent number: 4655124
    Abstract: Carbonating apparatus includes a reservoir to be filled with fresh water through an outlet. Rotation of a control opens a valve, so that water passes from the reservoir into a pressure vessel. The control is then depressed to cause pressurized gas to be introduced into the water in the vessel, via a nozzle, from a gas cylinder, so as to carbonate the water. A slidably-operable control is then moved by an initial amount to cause a venting valve to open, thereby venting excess gas in the vessel to atmosphere. Further sliding movement of the slidably-operable control depresses a lever connected to an outlet valve, which permits dispensing of the carbonated water from the vessel, via a spout.

  • Patent number: 4629126
    Abstract: A diffuser for air or other fluids has a rigid body with an upper disc portion having a series of radially projecting fingers about its perimeter. The fingers are relatively narrow and blunt. A diaphragm formed of a soft elastomer has a rim portion which receives the fingers. The diaphragm overlies the disc and normally closes a central opening in the body. Spaces at the base of the fingers are not covered by the rim portion of the diaphragm and air or other fluid escapes through those spaces when it is admitted under pressure through the central opening in the body. A circular cylindrical wall depends from beneath the disc at the bases of the teeth to discourage the fluid from collecting beneath the disc. In another embodiment, the spaces through which the fluid passes are covered by an open cell foam in the form of a ring that surrounds the wall and that is held in place against the rim portion by a plate mounted to the body and seated against the bottom of the wall.

  • Patent number: 4608209
    Abstract: In order to enable a carbureter body formed of a soft material such as a synthetic resin to be coupled easily between an air cleaner and a manifold pipe in its state of not developing a distortion, the carbureter for an internal combustion engine comprises: reinforcing members each having a high rigidity and a length greater than the full length of the carbureter body but smaller than the length obtained by adding this length of the carbureter body to the thicknesses of two elastic sealing members used in coupling the carbureter body to the air cleaner and to the manifold pipe; a plurality of arms for nipping the reinforcing members in their posture of being placed along a suction bore of the carbureter body. Shaft-receiving bores for supporting a throttle valve shaft and a choke valve shaft are disposed at locations at which these valve shafts are not affected by the strains which are apt to develop when the carbureter body is coupled to the air cleaner and to the manifold pipe.

  • Patent number: 4547325
    Abstract: Disclosed is a carburetor for internal combustion engines which minimizes the effect on the engine of carburetor ice.To overcome the effect of ice build-up the throttle valve on the side adjacent the idle jet, is bent upstream, thus providing a greater opening between the idle jet and the adjacent part of the throttle valve and a lesser opening on the opposite side of the throttle valve at idle and intermediate throttle openings. Increasing the operating angle of the idle jet half of the throttle valve upstream, toward the vertical position, deters the build-up of ice. Furthermore my invention exposes an ice deposit to the incoming fuel-air mixture, causing early erosion of the same and elimination of prolonged operation with over-rich or lean mixtures.
