[origin: JPH03121220A] PURPOSE: To enhance the control accuracy by enabling a position of a throttle valve which is determined as a function of a load, to be changed within a range of play distance, in a device transmitting a movement of an accelerator pedal to a throttle valve through a mechanical adjusting and coupling mechanism having a play. CONSTITUTION: A throttle valve 2 rotatably attached in an intake pipe 1 through the intermediary of a shaft 3 is opened and closed in response to actuation of an accelerator pedal (which is not shown) by means of a mechanical adjusting and coupling mechanism 4 and a drive lever 5. The mechanism 4 has a two part 6, 7 which are telescopically coupled together so as to exhibit a play having a distance 1 in the mechanism 4. The coupling part 6 is coupled to an accelerator pedal, and the coupling part 7 is coupled to a bell crank lever 10 which is swingable around a pivot 9. In this arrangement, the drive lever 5 is coupled thereto with a vacuum actuator 15 which can change a position of the throttle valve determined as a function of a load within a range of the play distance 1.

Die Erfindung bezieht sich auf eine Betätigungsvorrichtung für eine in einer Ansaugleitung in einer Dieselbrennkraftmaschine angeordneten Drosselklappe mit einem mechanischen Verstellgestänge zur lastabhängigen Verstellung der Drosselklappe, wobei das Verstellgestänge einen Leerweg aufweist. Um die Drosselklappe in Abhängigkeit mehrerer Betriebsparameter steuern zu können, wird ein hilfskraftbetätigter Stellantrieb vorgeschlagen, über den die lastabhängig vorgegebene Drosselklappenstellung innerhalb des Leerweges veränderbar ist.
