Each valve has a port 14 which in the deflected position of the element 10 (Fig. 4A, not shown) connects a pressure line 15 with an output conduit 15A. The rate of return of the valve is controlled by a pre-set bleed valve 19. The valves V 1 -V 6 , are connected to an averaging relay AR which produces a resultant signal in an output conduit L5. The signal gives a visual indication at S, and is fed through a conduit L6 to a variable speed drive VSD. The latter comprises a drive motor M having a variable speed pulley 32. The deflectable cone 31 of the pulley is operated by a piston 23 from a pressure line L7 via a valve CV controlled by the signal in the conduit L6. Detectors S1, and S2, sense any absence of backlog which may occur, and act via a valve SV1 to override the control signal. This slows down the drive motor to a minimum speed. Th signal may also be overriden manually by th operation of a control R4.

[Class 7 (iii)] [Also in Groups XXVI and XXIX] In carburetting-apparatus, the rate of delivery of fuel from a pump to the jet is maintained proportional to the speed of the engine by supplying the fuel to the jet through a passage provided with a centrifugally-controlled pressure-relief valve, and with a metering- orifice arranged between the jet and the relief valve. In Fig. 1, fuel is supplied by a pump to a passage 10, 22 leading past a metering- orifice 12 to the valve-controlled jet 11, a branch 15 from the passage 10 being fitted with a pressure-relief valve 16 connected to a piston 18 or diaphragm, the opposite sides of which are connected respectively by passages 24, 26 to the inlet and discharge of a centrifugal pump 25 driven at engine speed or a multiple thereof. The left-hand side of piston 18 is also connected to a passage 20 returning to the fuel pump past a valve 21 having a balancing- piston connected by a passage 23 to the passage 22. The metering-orifice 12 may be controlled by a needle valve 13 adjusted in accordance with the inlet-manifold pressure, temperature, exhaust back-pressure, &c. In a modification, the left-hand side of piston 18 is shut off from the valve 16, and the two sides of the piston are connected respectively to the two sides of the metering-orifice past adjustable leaks in the form of passages controlled by needle valves. There may be two of these needle valves in the passage from the left of piston 18, one of which may be cut out by a byepass valve actuated by a cam adjustable with the engine throttle, so as to provide a richer mixture when.accelerating. To facilitate starting, a plunger operated by fuel pressure against a spring may be arranged .to bear on the righthand side of piston 18 so as to open the relief valve 16, until the fuel pressure rises sufficiently, after starting to force the plunger away from the piston 18 and leave the valve 16 free.
