DEVICE FOR GIVING OUT DOSES OF A FLUID

摘要

A device for dosed release of a fluid from a source (4) for this fluid to a receiver (12) via a pipe (8). The device comprises an influencing device (2) for influencing the release of the fluid from the source (4), and a control device (30) for control of the influencing device. According to the invention the device comprises a fluid accumulator (20) which communicates with the pipe (8) at a location (16) between the influencing device (2) and the receiver (12). The influencing device (2) is an electrically operated shut-off valve which is arranged to be opened by means of impulses from the control device (30) when the pressure of the fluid in the accumulator (20) has reached a minimum value (P1min), and to be closed when this pressure has reached a maximum value (P1max). When the shut-off valve (2) has been closed and the accumulator (20) has been filled, the accumulator (20) effects release of the fluid to the receiver (12).
