A method and an apparatus for a repeatable dosing or metering of fluids and in particular liquids in a selectable and reproducible amount in which the fluid amount to be dosed is learned in a dosing operation effected manually once and stored in a retrievable way; the apparatus comprises a fluid line 2 for a fluid 1 including a fluid inlet 3 and a fluid outlet 4 between which a shut-off device 7 controlled by a control unit 8 is provided, an operation 5 and a memory input 9 a learning mode is initiated and that by once pre-dosing a corresponding quantity information is stored and that by operating the memory input 9 a dosing mode is initiated in which the fluid amount corresponding to the stored quantity information is dosed by the shut-off device.

[ What is claimed is:] [1.] Apparatus for the reproducible dosage of a fluid (1) in an amount which can be predetermined, comprising:a fluid line (2) comprising a fluid inlet (3) and a fluid outlet (4),a shut-off device (7) provided in the fluid line (2) between the fluid inlet (3) and the fluid out
[ What is claimed is:] [1.] Apparatus for the reproducible dosage of a fluid (1) in an amount which can be predetermined, comprising:a fluid line (2) comprising a fluid inlet (3) and a fluid outlet (4),a shut-off device (7) provided in the fluid line (2) between the fluid inlet (3) and the fluid outlet (4), and allowing to switch the flow of a fluid (1) on and off,an electronic control and detection unit (8) controlling the shut-off device (7),operating means (5) connected to the control and detection unit (8) and delivering signals to the control and detection unit (8) upon operation by an operator, whereupon the control and detection unit (8) closes the shut-off device (7), andinput means connected to the control and detection unit (8) for putting in input information by an operator concerning the amount of fluid (1) to be dosed,characterized in thatthe input means are input and memory means (9) (M, SP; MSP) delivering signals to the control and detection unit (8), or receiving signal information to be stored from the control and detection unit (8) andthe control and detection unit (8) is designed such that it,(A) upon one single manual dosing of a fluid amount by an operator by operatingthe operation means (5) and/orthe input and memory means (9) (M, SP; MSP)in a predetermined order in a learning mode initiated thereby,determines the amount of fluid (1) discharged from the fluid outlet (4) between the opening (ON) of the shut-off device (7) effected via the operation means (5) and/or the input and memory means (9) (M, SP; MSP) and the subsequent closing (OFF) of the shut-off device (7) effected viathe operation means (5) and/orthe input and memory means (9) (M, SP; MSP)as an amount information corresponding to that amount, and stores it as learned amount information in a memory allocated to the input and memory means (9) (M, SP; MSP),the learning mode being terminated after the amount information has been stored, and,(B) upon invocation of a learned amount information through operation of the input and memory means (9) (M, SP; MSP), optionally in combination with an operation of the operation means (5), changes over into a dosing mode, during which the learning mode is blocked and the memory is not overwritable, and opens the shut-off device (7) (ON) and closes it (OFF) in a controlled manner such that the amount of fluid (1) discharged from the fluid outlet (4) between the opening (ON) and the subsequent closing (OFF) of the shut-off device (7) corresponds to the amount information previously learned and stored in the memory in the learning mode, the dosing mode being terminated with the closing of the shut-off device (7), wherein the control and detection unit (8), the operation means (5) and the input and memory means (9) (M, SP) are designed such that for the learning mode one of the functional combinations of operations of the operation means (5) and/or of the input and memory means (9), (M,SP) at learning start and learning end listed off in the following function table is realized:______________________________________ Operation(s) at learning start at learning end (5) (M) (SP) (5) (M) (SP) ______________________________________ 0 1 0 0 0 1 0 1 0 1 0 1 0 0 1 0 1 0 0 0 1 0 1 1 0 0 1 1 1 0 0 0 1 1 1 1 0 1 1 1 0 0 1 1 0 0 0 1 1 1 0 1 0 1 1 0 1 0 1 0 1 0 1 1 1 0 1 1 1 1 0 0 1 0 0 0 1 1 1 0 0 1 1 1. ______________________________________
