Zusammenfassung:	The compressibility of the fluid to be dosed is utilised, by arranging that a cavity 1 of substantially constant volume and which in use remains filled with the fluid, is first placed in communication with an inlet 2 which supplies fluid at a relatively high pressure P1 so that some of the fluid enters the cavity, and is then isolated from the inlet 1 and is placed in communication with an outlet 3 which is at a lower pressure P2 so that the fluid in the cavity expands and a predetermined precise, small amount flows into the outlet. Several cavities, inlets and outlets may be provided in two or more members, such as ceramics discs, which are relatively movable by oscillation or rotation to provide simultaneous or continuous successive doses. Such devices may be used to distribute doses to several outlets or to mix doses of fluids from different inlets into a common outlet.
