Abstract

435,471. Spray carburetters ; fluid-actuated valves. JACOBY, H. E., 9, Hofstrasse, Wetzikon, and NUESSLI, H., 9, Bahnhofstrasse, Hinwil, both in Switzerland. March 23, 1934, No. 9142. [Class 7 (iii)] [See also Group XXIX] The throttle is actuated by a device subject to the suction in the mixing chamber, the suction effect on the device being controlled by a member actuated by the accelerator pedal. An arm 6 on the throttle valve 5 is connected by a link 13 to the rod 11 of a piston 9 movable in a cylinder 8 and loaded by a spring 10. The control member comprises a casing R in which a valve 15 is adapted to be rotated through a spindle 14 by the accelerator pedal. The casing has a pipe c leading to the mixing chamber on the engine side of the throttle 5, a pipe a leading to the cylinder 8 above the piston 9, and pipes e, f, g leading to the cylinder below the piston through the medium of a branch pipe b. The pipes f, g, b are provided with constrictions v, x, z respectively. During idling, the valve 15 is in a position to close pipes e, f and to open pipes g, a, the result being to maintain piston 9 in its lowest position and the throttle valve closed. The constriction x prevents a sudden closing of the throttle and consequent spurting of fuel from the nozzle. When the accelerator pedal is depressed, for part opening of throttle, the valve 15 is in the position shown in Fig. 2, with the pipes e, g, closed, the pipe f open to atmosphere, and the pipe a in communication with the mixing chamber through a constricted part of a bore in valve 15. The result is that the piston 9 is raised through part of its travel and partly opens the throttle valve, the movement being damped by the constriction v. When the accelerator pedal is fully depressed, the valve 15 is moved to a position, Fig. 3, where pipes e, f are open to atmosphere, and pipe a to the mixing chamber without any damping effect and the throttle is fully opened. When the engine is cold, a piston 21 of a device T may be actuated by a thermostat to open a pipe p and partly destroy suction in cylinder 8 and cause the throttle to move forwards its closing position. In a modification, Fig. 5 (not shown), the rod 11 of piston 9 actuates a plunger in an auxiliary cylinder to force air into the float chamber, as the piston rises, and increase the flow of fuel.
