The spring diverting valve of the compound water meter is produced as a seat valve, preferably in the short overall length and is provided for automatically diverting the water flow from the auxiliary counter to the primary counter and inversely. Said valve comprises a complete switching insert (6) having a plurality of sliding bolts (17) arranged outside the area of entry. The control and closing element (7) which is subjected to the load exerted by a plurality of pressure springs (18) is guided on said sliding bolts. The opening and closing functions are carried out on or in a banking-up step (44) (conically shaped) by means of a control disc (11) having a narrow control edge (43) on the outer diameter (42). The sealing element located in the switching unit is an elastic sealing ring (26) or the like which mounted in a cavity in order to increase the elasticity thereof. An advantage provided by this diverting valve type is that no centrally arranged sliding bolt hub having retaining ribs is provided on the conically restricted main passage. By using the diverting valve, the auxiliary current is directly conducted into the switching unit. |
