Abstract: The invention relates to a throttle valve device consisting of: a housing (4; 54; 54'; 98), a throttle valve spindle (3; 53; 53'; 99) on which a throttle valve (2; 52; 52'; 100) movable in the housing (4; 54; 54'; 98) between a first air passage chamber (62; 62'; 92) and a second such chamber (63; 63'; 103) leading to the vehicle engine is held in at least one closed position (DS), an idling position (MS) and a full-throttle position (VS); and: a control unit (11; 61; 61'; 107) comprising at least one control motor unit (5; 55; 55'; 91) and connected to the throttle valve spindle (3; 53; 53'; 99). The second air passage chamber (63; 63'; 103) is connected to a back-up air control device (2, 3, 8, 9, 10, LHP1; 52, 55, 58, LHP2; 52', 55', 58', LHP3; 95, 102) by means of which enough air can be fed to the engine in the event of the breakdown of the control motor unit (5; 55; 55'; 91) to allow vehicle movement.

Throttle device for internal-combustion engine
Yasuo Saito,Yoshikatsu Hashimoto,Eisuke Wayama,Toshifumi Usui +3 more
- 19 Nov 2002
TL;DR: In this paper, a throttle device for an internal-combustion engine is described, in which, on one side of the side wall of a throttle body, there are formed a space for mounting a reduction gear mechanism which transmits the power from a motor to a throttle valve shaft and a default opening setting mechanism for holding the throttle valve opening at a specific opening (default opening) when the ignition switch is in off position.
