Abstract:
Metering device for the metered admixture of a first fluid in a second fluid, comprising a housing (10) with a first inlet (15, 16) for the first fluid, a second inlet (11) for the second fluid, and an outlet (14) for a mixture of the two fluids, in conjunction with which the housing (10) contains a moving body (18) which is so arranged as to be influenced by a flow of fluid through the housing and exhibits means for regulating the first fluid, in such a way that a change in the flow at the outlet (14) produces a change in the flow of the first fluid, wherein the inlet (15, 16) for the first fluid is connected to a tubular channel (17), which is centred essentially coaxially inside the outlet (14), in that the body (18) is mounted so that it is capable of displacement along the outside of the tubular channel (17), against the effect of a spring device (21) acting in the oppostie direction to the flow, and in that the tubular channel (17) is provided with at least one opening (22) for the first fluid, which opening is exposed as the body (18) is displaced in a direction downstream.
