Rehabilitation support

A fuel removal system for a carburetor with a float bowl carried by a body having a channel extending from the float bowl to the exterior of the carburetor body. An outlet tube is positioned within the channel and is movable from a first position wherein liquid fuel can be removed from the fuel bowl to the exterior of the body, and a second position wherein the outlet tube does not communicate with the float bowl.

Fuel removal system for a carburetor

A solenoid winding and housing for use with an armature actuated fuel poppet valve and the process of applying interior and external annular plastic shields on and in the housing to seal against moisture and fuel and to provide joint and weld protection. A prong housing for the solenoid winding ends is molded along with the exterior molded shields. Noise insulation as well as protection of parts is provided with the molded shields.

Solenoid winding case and protective overmold and method of making

A fuel and air assembly is provided for furnishing an air and fuel mixture under pressure to a cylinder of an ignition fired internal combustion engine which utilized a solenoid-actuated valve timed to admit the mixture to the cylinder. A standard fuel injector is interfaced with one end of a mixing insert which is connected at the other end to an air passage of a fuel rail. At one side of the insert is an outlet passage leading to the solenoid actuated valve which has an outlet end shaped to enhance fuel distribution and combustion. The mixing insert contains an air filter and passages to conduct air to the common passage for air and fuel. The insert is captured in the fuel rail between a locating shoulder and the fuel injector for proper positioning relative to the timed valve. An adapter cap on the solenoid assembly joins the insert to the valve controlled passage to the cylinder.

Fuel and air injection for multi-cylinder internal combustion engines

A fuel shut-off valve for an internal combustion engine carburetor which includes passages leading from a fuel source to a controlled fuel passage. A valve seat is interposed between these passages disposed to be closed by a plunger type valve biased toward the valve seat by a coil spring. An actuator for the valve includes a configuration to keep the valve from rotating and a cross-pin transfixing a valve stem on the plunger type valve. A cam lever has a collar surrounding the valve stem with cam surfaces to engage the cross-pin which upon rotation will lift the valve off of the valve seat. A radial detent groove at the top of the cam surface receives the cross-pin to establish the open position of the valve. Release of the pin from the detent groove causes the pin to ride down the cam surface under the bias of the spring to a closed position.

Fuel shut-off valve

A double coil spring assembly to serve as a closing force for throttle valves of carburetors or throttle bodies, the spring assembly including an integral spool with inner and outer arbors supported on a closed end to separately support inner and outer coil springs, there being lands on the outer arbor to position axially the outer spring, and the inner spring as an installable component in the assembly of the carburetor or throttle body.
