Control apparatus of a throttle valve in an internal combustion engine
This patent describes a control apparatus of a throttle valve in an internal combustion engine having a manually operable accelerator means. The control apparatus consists of: a spring means biasing the throttle valve in the direction in which the throttle valve is caused to open; a first operating means mechanically connected to the manually operable accelerator means and selectively engageable with the throttle valve against the spring means for restricting the opening position of the throttle valve; and a second operating means selectively engageable with the throttle valve against the spring means independently of the first operating means for restricting the opening position of the throttle valve; the first operating means and the second operating means being engageable with the throttle valve independently of and parallel to each other to determine a throttle opening of the throttle valve by one of the first and second operating means being engaged with the throttle valve, the other of the first and second operating means being disengaged from the throttle valve.
