    摘要: In known air flow rate meters, the initial tension of a spiral spring, which generates the restoring force on the baffle valve, is adjusted by the snapping of a locking spring into gaps between the teeth of a tooth ring provided on the spring housing. However, the tooth spacing cannot be made arbitrarily small. Accordingly, a way to enable finer adjustment of the initial tension is needed, so that a measurement can be made even at low idling speeds and with a small aspirated air quantity. In the air flow rate member according to the invention, the locking spring engages a detent element, which facing the toothed ring has an inside serration, the spacing of the teeth of which is less than the spacing of the toothed ring; when the spring housing rotates, detent increments that correspond to the spacing of the inside serration are attainable. Quite generally, the embodiment according to the invention enables sensitive adjustment and locking of a spiral spring serving as a restoring force.

    摘要: An apparatus for detecting the pressure and temperature in the intake tube of an internal combustion engine. A temperature sensor and a pressure sensor are secured to a carrier together with an evaluation circuit in a common housing with as little strain as possible. The housing includes at least two chambers separate from one another, one of which forms a pressure chamber that communicates with the intake tube via a stub and is sealed off from the environment in which the pressure sensor is secured. The other chamber serves to secure the temperature sensor therein by use of connection elements, and sealing adhesive connections that decouple mechanical strains for securing the carrier and sealing off the pressure sensor.
