Abstract: A throttle body for an internal-combustion engine having a hollow venturi member positioned within the body. The member has a first portion projecting out of the body at its intake end, and a second portion positioned generally centrally within the body air duct upstream from a throttle plate. The second portion has an exterior surface spaced inward from the body interior sidewall to form an annular venturi passage therebetween. The first and second portions define an enclosed air channel. Circumferentially distributed entry openings in the first portion open exterior of the body duct for entry of air into the channel, and circumferentially distributed exit openings in the second portion communicating with the venturi air passage for the exit of air from the channel. The channel and the entry and exit openings define a sample flow path of air from a location exterior of the duct to a location adjacent to the venturi passage representative of the air mass flow through the duct.

Abstract: An electronic anemometer for measuring air mass flow in a conduit having a straight length of temperature-dependent resistive wire; a circuit board for holding at least a portion of the electronic circuitry used when the anemometer is operating to maintain the wire at a substantially constant temperature and generate an air mass flow-indicating signal based upon the air mass flow in the conduit sampled by the wire, the circuit board being mountable on the exterior of the conduit; a rigid support plate having a pair of spaced-apart openings, the plate being fixedly attached to the circuit board; a pair of electrically nonconductive support inserts, each of the inserts being fixedly retained within one of the openings in the support plate; and a pair of electrically conductive, resilient posts capable of withstanding the elevated operating temperatures encountered when the anemometer is operating, each of the posts having a wire-supporting end portion fixedly connected to the wire, the end portions being spaced
