Abstract:
A carburetor may have a fuel metering assembly with a metering valve and a metering diaphragm sealed to a body of the carburetor to at least partially define a metering chamber with a portion of the metering diaphragm movable relative to the body to actuate a fuel metering valve. The diaphragm may include a continuous layer, a discontinuous layer, and an intermediate layer received at least partially between the continuous and discontinuous layers and at least partially inhibiting direct contact between the continuous and discontinuous layers. The continuous and discontinuous layers may be different polymer materials and the intermediate layer may be a polymer different than that of the discontinuous layer. The intermediate layer may include voids, segments, or a wire form.
