DEVICE FOR DISCHARGING A METERED MIXTURE OF TWO LIQUIDS

摘要

This invention relates to a device for the constant replenishment of an animal dipping bath, or for use in any situation where it is desired to have a concentrate diluted with a liquid with little or no liquid supply pressure. The device consists of a two-component rocking-pan arrangement 8 and 9 for receiving and discharging the mixture and a metering arrangement for discharging concentrate in the pan. The metering arrangement consists of a double acting single piston and cylinder pump, linked to the pan, and comprises a single piston 22, and a single cylinder partitioned by the piston into 2 chambers, 25 and 26 each chamber being capable of receiving and discharging quantities of concentrate. The arrangement of the pump is such that when one chamber is discharging concentrate into the pan the other is receiving concentrate from the supply line, and concentrate is delivered to that one of the two components which is about to be filled with diluent. The device is particularly useful for sheep-dipping purposes.
