Description

Patentkrav 1. Justerbar reguleringsindsats (2) ti! ventiler, især til styring af væskestrømning i et anlæg for centralvarme eller luftkonditionering, hvilken indsats (2) omfatter en kopformet del (7) med indstrømningsåbninger (8) og udstrømningsåbninger (9), idet udstrømningsåbningerne (9) aflukkes i afhængighed af trykdifferencen over indsatsen (2) under indvirkning af en fjeder (15), der søger at holde udstrømningsåbningerne (9) åbne, hvilken indsats (2) endvidere er forsynet med midler til justerbar aflukning af indstrømningsåbningerne (8), hvilke midler omfatter en i forhold til en kappe (24) roterbar aksel (18) med en til omgivelserne blottet ydre ende (19), kendetegnet ved, at indsatsen (2) yderligere omfatter - en i forhold til kappen (24) løs bøsning (20), der er i rotationsfast men aksi-alt forskydeligt indgreb med akslen (18), hvilken bøsning (20) er forsynet med et udvendigt gevind, - en medbringer (21) forsynet med et indvendigt gevind, som er i indgreb med bøsningens (20) udvendige gevind, og som er i rotationsfast men aksi-alt forskydeligt indgreb med kappen (24), - idet der er tilvejebragt en indadragende vulst (27) i kappen (24), som i en yderposition af medbringeren (21) forhindrer videre aksial forskydning heraf ved fortsat rotation af akslen (18) i én retning, hvorved de samvirkende gevind på henholdsvis bøsningen (20) og medbringeren (21) forårsager, at bøsningen (20) forskydes aksialt udad på akslen (18) mod dens blottede ydre ende (19). 2. Indsats ifølge krav 1, kendetegnet ved, at indstrømningsåbningeme (8) er forhindret i at blive aflukket fuldstændigt, når bøsningen (20) forhindrer indgreb med akslens (18) blottede ydre ende (19).Patent claim 1. Adjustable regulation insert (2) ti! valves, in particular for controlling fluid flow in a central heating or air conditioning system, which insert (2) comprises a cup-shaped portion (7) with inflow openings (8) and outflow openings (9), the outlet openings (9) being closed in response to the differential pressure across the insert (2) under the action of a spring (15) which seeks to keep the outlet openings (9) open, which insert (2) is further provided with means for adjustable closure of the inlet openings (8), which means comprise one relative to a jacket. (24) rotatable shaft (18) with an outer end (19) exposed to the surroundings, characterized in that the insert (2) further comprises - a sleeve (20) which is rotatably but axially loose in relation to the sheath (24). -all displaceable engagement with the shaft (18), which bush (20) is provided with an external thread, - a carrier (21) with an internal thread which is in engagement with the external thread of the bush (20) androtationally but axially displaceable engagement with the sheath (24) - providing an inwardly extending bead (27) in the sheath (24) which prevents further axial displacement thereof by continued rotation of the shaft (21) 18) in one direction, whereby the cooperating threads on the bushing (20) and the carrier (21) respectively cause the bushing (20) to be displaced axially outwards on the shaft (18) towards its exposed outer end (19). Insert according to claim 1, characterized in that the inflow openings (8) are prevented from being completely closed when the bushing (20) prevents engagement with the exposed outer end (19) of the shaft (18).
