Abstract (en)
[origin: EP0667491A2] The pump (10) is driven by an electric motor (11), supplying fuel to the jet through a stop valve (14). Fuel flows to and from the pressure balancing hydraulic reservoir (42) through the restrictor (25) and two-way valve (29), which spills to the junction (39), thence to the pump suction. On light-up, a small amount of fuel is fed through the restrictor and the pilot valve (29), passing through the feed pipe (40) to feed the pilot flame. After a certain time, the electro magnet (31) is desensitised, closing pilot valve (29). Pressure through the restrictor and the valve (29) balances the force of the accumulator piston in normal operation. If the burner is shut down, the electromagnets (16) and (27), which are always operated together, are deactivated.
