摘要： An assembly for actuating the reversing gear and the gas throttle of an internal-combustion engine, comprising a first lever for actuating the reversing gear and a second lever for actuating the throttle, the first lever being rotatable around a fixed axis and the second lever being mounted on a pivot on the first lever which pivot does not coincide with said fixed axis. The second lever is also used as an operating handle. During the first part of the stroke of this operating handle on either side of the neutral position, the extremity of the second lever lying in the vicinity of the fixed axis of the first lever is guided by guiding surfaces in such a manner that both levers substantially move as a unit, but after leaving these surfaces the second lever is independently movable around its pivot and the first lever is blocked in its extreme position.

摘要： The present invention provides an oil pressure control device for an automatic transmission of vehicles, in which an oil pressure proportional to the opening of the throttle is applied through the aid of springs to the pressure control valve for controlling the pressure acting on the servosystems. The oil pressure is increased to a prescribed level in proportion to the throttle opening, but once at that level, the oil pressure is maintained constant regardless of any additional increment of the throttle opening, so as to improve the operation and efficiency of the transmission without changing the throttle pressure Pth.
