Patent ID: 7036789

Claim:
A distribution valve with flow meter for the use in the inlet of a hot water heating circuit, with a housing forming the inflow conduit, a branch line extending from the housing and an adjusting and measuring unit formed separately from the housing and arranged at the housing opposite the branch line and penetrating the housing wall, for the adjusting and displaying of a flow rate of a medium flowing through the branch line, wherein the adjusting and measuring unit comprises a valve closing body, which is operatively connected to an adjusting spindle in such a manner that it forms, together with a valve seat body which during conventional operation is stationary relative to the housing, a valve gap, which is adjustable by a rotating of the adjusting spindle for the adjusting of the flow rate, and wherein the adjusting and measuring unit includes a flow against member, which is located in a flow channel, through which in operation substantially the complete medium flowing off through the branch line flows, wherein the position of the flow against member in the flow channel is adjustable beginning from a starting position by a flow which flows from the valve gap to the branch line dependent from the flow rate, and wherein the flow against member is operatively connected to display means of the adjusting and measuring unit, which may be read off from the outside, in such a manner that different positions of the flow against member in the flow channel cause different displays of the display means, wherewith the respective flow rate through the branch line can be read at the valve at its outside, characterized in that the distribution valve is designed in such a manner that the flow exiting the valve gap during conventional operation is deflected prior to its impinging onto the flow against member at least twice, namely initially by a first sense of rotation in a first direction and thereafter by a second sense of rotation opposed to the first sense of rotation in a second direction.
