Flushing-in tank for the automatic metering of a washing agent

摘要

In the flushing-in tank 1 there is arranged an axially movable float body 9 which moves upwards during filling of the flushing-in tank 1 with cleaning solution and in the process lifts an actuation rod 10 which, via a lever 11 and a catch 12, advances the locking disc 14 of a counter mechanism 15 by one tooth 13. The position of the marking 16 on the locking disc 14 indicates how often the locking disc has been advanced. For monitoring of the subsequent repeated flushing-out of the flushing-in tank 1 with water, the first of these flushing-outs is registered by the counter mechanism 15 and the actuation rod 10 is simultaneously arrested, via the valve body 18 and rocker arm 20, in its upper position. Subsequent water flushings are by this means not counted. Only with the next filling of the flushing-in tank 1 with cleaning solution is, by virtue of the subatmospheric pressure then prevailing in the flushing-in tank 1, a downwardly directed force exerted on the actuating rod 10 of such magnitude that the latter is moved downwards again against the rocking moment of the rocker arm 20. <IMAGE>
