Definitions
- the invention relates to a potentiometer arrangement for an internal combustion engine, for Control of adjusting elements arranged on a shaft such as e.g. B. Air intake ducts of a suction pipe, throttle valves etc., with fixed to the shaft connected grinder elements arranged with stationary Resistance tracks are in contact, with both the grinder elements as well the resistance tracks are arranged in a potentiometer space.
- a shaft such as e.g. B. Air intake ducts of a suction pipe, throttle valves etc.
- Such a potentiometer arrangement is, for example, from DE-U-84 22 232 known.
- the grinder elements and the resistance tracks of the Potentiometers arranged in a room by a housing wall section, in In the present case, an intake manifold wall section and an intermediate wall element and a lid is formed. The electrical contacting of the Potentiometers take place over conductor tracks arranged in the intermediate element.
- the invention has for its object to a potentiometer arrangement provide which avoids the disadvantage mentioned above and at the same time insensitive to those located in the engine compartment of the internal combustion engine Is dirt particles.
- cover element that from a Thermoplastic material with a molded elastomer as a sealing element.
- This cover element is in the so-called 2-component injection molding process producible, the cover element first being in a workpiece clamping such is sprayed out leaving a radially circumferential annular gap, which is subsequently sprayed out using an elastomer, which then does the above called sealing element forms.
- connection between the cover element and Housing wall section to be made by an interference fit.
- the drawing shows a section of a shaft 1 for the adjustment of not Air intake ducts of a suction pipe 2 shown.
- the shaft 1 can pass through a gear transmission 3 are driven.
- the gear 3 for driving the In the present case, shaft 1 is located in a housing 4 thereof Housing wall section 5 is formed step-like. It is in Housing wall section 5 a mounting plate 6 with resistance tracks 7 a Potentiometers 8 arranged.
- a grinder arm 9 is fixed Has grinder elements 10 which are in contact with the resistance tracks 7.
- In the housing wall section 5 is also a cover member 11 by means of a Press fit used that a potentiometer space 12 thus formed closes.
- the cover element has an elastomer seal 13 on the in the present case attacks both on the housing wall section 5 and on the suction pipe 2 and accordingly the potentiometer space 12 and the interior of the intake manifold seals with respect to the environment.
- the electrical contacting of the Potentiometers 8 take place via conductor tracks arranged in the housing wall section 5 14 instead.
