Abstract

765,813. Regulating; spray carburetters. SOC. ANON. A. CITROEN. Oct. 1, 1954 [April 23, 1954], No. 28302/54. Classes 7 (3) and 7 (6). The movement of a throttle valve towards its idling position is retarded by a dashpot device comprising a stem A contacted by a screw K on the throttle valve control lever T and connected to a diaphragm M the space above which is filled with liquid the flow of which into a reservoir R when the diaphragm is urged upwards by the return movement of the throttle valve is throttled by a ball valve B which normally rests on a grating G but is moved by the liquid flow towards a tapered orifice C by an amount limited by an adjustable stop H. The diaphragm is urged downwards to maintain the stem A in contact with the screw K by a spring W and the liquid in the dashpot may be hydraulic fluid, lubricating oil or fuel. In a modification Fig. 3 the dashpot M is mounted at the base of the carburetter float chamber O, the diaphragm being forced downwards when the throttle valve is released.
