Abstract

1531452 Flushing cistern NEWBOULD ENG SERVICES Ltd 10 Nov 1975 [7 Jan 1975] 25402/78 Divided out of 1531451 Heading E1C A siphonic flushing cistern comprises a conventional inverted-U siphon in which the piston is operated by a solenoid actuated by a manual or proximity switch and a means for disabling the operation of the solenoid for an interval of time following each operation which prevents its operation again until the water level returns to a pre-determined level. The disabling means may comprise a microswitch 56 with an arm 58 and roller 60 actuated by a cam 66 on a rod 62 the adjutsable cap 68 of which rests on the float arm controlling the water inlet valve. The microswitch may also operate a pilot light and/or an electric water supply pump. The piston may be connected to the armature 40 of the solenoid 39 via links 50, 52, a lostmotion linkage 47, 48 and a lever 42, a universal joint may also be included. The cistern may be arranged to give a full or partial flush.
