Bottom of housing is made of gauze whose cells form outlet holes. Placed on said gauze are several layers of Rushing or pall rings closed by other gauze secured on flange connecting housing with cylindrical inlet branch pipe in which second contraction inert is installed lower than first contraction at level of lower edge of which holes are cut out in inlet branch pipe overlapped by cup made of capillary porous material whose lower edge is lowered into water-filled cylindrical reservoir open from top and secured around inlet branch pipe. Upper contraction insert is provided with ball valve installed for partial or complete overlapping of its cross section, and valve proper is provided with manual drive secured on surface of inlet branch pipe.
