Distribution valve

Abstract

The invention concerns a distribution valve for the use in the feed or return of a medium circuit, with a housing (1) forming the feed line or the return line, respectively, a branch line (2) branching off from the housing (1) and an adjusting unit (3) for adjustment of a flow of medium through the branch line (2), which adjusting unit is formed separately from the housing (1) and opposite to the branch line (2) is arranged at the housing (1) and protrudes the housing wall. The adjusting unit (3) comprises an adjusting spindle (4), the axial position of which with respect to a component (5) of the adjusting unit (3) which is connected to the housing (1) can be changed by twisting it relative to said component (5), thereby changing the flow rate. The valve is designed in such a manner that an axial movement of the adjusting spindle (4) relative to the component (5) in direction towards the branch line (2) effectuates an increase of the flow rate through the branch line (2). Furthermore, adjustable stopper means are present, by means of which, through abutting of a first abutment face (7) which is connected with the adjusting spindle (4) against a second abutment face (8) which is connected with the housing (1), an axial movement of the adjusting spindle (4) with respect to the component (5) in direction towards the branch line (2) can be limited at a specific axial position, for limiting the maximum flow rate through the branch line (2) that can be adjusted. The invention makes it possible to provide in a cost-efficient manner very compact and simple designed distribution valves at which a once adjusted limitation of the maximum flow rate is preserved in case of a temporarily closing or decrease of the flow rate.
