Abstract
378,025. Fluid-actuated valves. SOC. GENERALE DES CARBURATEURS ZENITH, 26, Rue de Villiers, Levallois- Perret, Seine, France. May 1, 1931, No. 12932. Convention date, May 1, 1930. [Class 135.] A fuel control valve 3 moves in a chamber 1 having inlet and outlet passages 2, 4 respectively, one element of the wall of the chamber being constituted by a deformable membrane 5 the inner face of which is bathed by the fuel. This membrane is actuated by another membrane 7 subjected to a pressure difference produced by the working of the engine. For example, suction may be transmitted to the chamber 6 through a pipe 12, the outer face of the membrane being exposed to atmospheric pressure. The membranes are loaded by a spring 8 which is sufficiently stiff to prevent the valve 3 from being opened by fuel pressure on the diaphragm 5. In a modified construction, Fig. 2, the rod 9 does not positively connect the membranes as in Fig. 1, but acts through a lever 18 pivoted at 19. The spring 8 does not therefore force the valve to its seat, with consequent possibility of hammering, as in the construction shown in Fig. 1. Further, the valve 3, which is loaded by a light spring 16, tends to be closed by the pressure of fuel on the membrane 5. To avoid pulsations being transmitted to the membrane 7, a constricted orifice 23, or a series thereof, is inserted in the pipe 12. The unidirectional control between the membranes 7, 5 is produced in a modification, by means of a head on the valve spindle 9 engaging, with lost motion, a fork on the rod connected to diaphragm 7. In a further modification, Fig. 4 (not shown), the two membranes form opposite walls of one large chamber, and the space between the membranes is connected to a compressor which supercharges the engine. The Specification as open to inspection under Sect. 91 (3) (a) describes also a still further modification wherein the larger membrane is subjected to the pressure of the engine lubricating oil and carries a spindle which actuates the spindle 9 of the valve 3 with a certain amount of lost motion. This subject-matter does not appear in the Specification as accepted.
