Description

454 425 Till inloppsgänganslutningen 14 går en matarledning 21 och från utloppsgänganslutningen 15 går en ledning 22 till fordonsdäcket. 454 425 A supply line 21 goes to the inlet thread connection 14 and a line 22 goes to the vehicle tire from the outlet thread connection 15.

Funktion Däcktryckstyrventilen är normalt stängd. Om trycket i däcket skall sänkas eller höjas, kommer från reglersystemet via matarledningen 21 till att börja med en tryckökning från 0 till det önskade, nya däcktrycket. När det ökande trycket överstiger 0,1 MPa, öppnar styr- ventilen. Nu kan - efter erforderlig lufttillförsel eller luftbort- ledning - tryckluft strömma till eller från däcket genom styrven- tilen.Function The tire pressure control valve is normally closed. If the pressure in the tire is to be lowered or raised, a pressure increase from 0 to the desired new tire pressure comes from the control system via the supply line 21 to begin with. When the increasing pressure exceeds 0.1 MPa, the control valve opens. Now - after the required air supply or air diversion - compressed air can flow to or from the tire through the control valve.

När däcket erhållit önskat tryck, avluftas matarledningen 21 plöts- ligt och vid strypningarna 18 och 19 uppträder högt tryckfall så att membrankolvkroppen 7 avbryter förbindelsen med sitt ventilelement 9 och avstänger däcket. Genom att de båda strypningarna 18 och 19 är anordnade den ena efter den andra uppnås säkrare stängningsför- lopp, eftersom det kritiska tryckförhâllandet i ett extremfall rå- der vid varje enskild strypning och ett högt däcktryck därigenom nedstrypes så att ventilen 9/13 med säkerhet stängs.When the tire has reached the desired pressure, the supply line 21 is suddenly vented and at the throttles 18 and 19 a high pressure drop occurs so that the diaphragm piston body 7 interrupts the connection with its valve element 9 and shuts off the tire. By arranging the two throttles 18 and 19 one after the other, a safer closing process is achieved, since the critical pressure ratio in an extreme case prevails at each individual throttle and a high tire pressure is thereby throttled so that the valve 9/13 is closed with safety. .
