Conclusies
1. Een uitlaatgasnabehandelingssamenstel dat is geconfigureerd om samen te werken met een dieselverbrandingsmotor, welk samenstel omvat: - een uitlaatgascompartimentbehuizing (1); - een dieseldeeltjesfilter (2) en een dieseloxidatiekatalysator (3) beweegbaar aangebracht in de uitlaatgascompartimentbehuizing (1), waarbij het dieseldeeltjesfilter (2) en de dieseloxidatiekatalysator (3) cilindrische structuren zijn met cirkelvormige dwarsdoorsneden en axiaal naast elkaar geplaatst zijn op een onderling verbonden manier om een patroon (4) te vormen; - afstandsmiddelen (5) aangebracht tussen de patroon (4) en de uitlaatgascompartimentbehuizing (1); waarbij de afstandsmiddelen (5) een metalen persing (5A) omvatten met een vlak basisgedeelte (6) gepositioneerd tegen een binnenoppervlak (1A) van de uitlaatgascompartimentbehuizing (1), waarbij de metalen persing (5A) een aanslaggedeelte (7) omvat aan een eerste uiteinde van het vlakke basisgedeelte (6), waarbij het aanslaggedeelte (7) zich dwars uitstrekt vanaf het vlakke basisgedeelte (6) weg van het binnenoppervlak (1A) van de uitlaatgascompartimentbehuizing (1), met het kenmerk dat de metalen persing (5A) ringvormig is en het vlakke basisgedeelte (6) losjes gepositioneerd is tegen het binnenoppervlak (1A) van de uitlaatgascompartimentbehuizing (1), dat de metalen persing (5A) aan een tweede uiteinde van het vlakke basisgedeelte (6) tegenover het eerste uiteinde een veerkrachtig opneemprofiel (8) omvat dat is geconfigureerd voor het opnemen van een afdichtmiddel (9) dat direct contact maakt met het binnenoppervlak (1A) van de uitlaatgascompartimentbehuizing (1) en gepositioneerd is tussen het binnenoppervlak (1A ) van de uitlaatgascompartimentbehuizing (1) en het veerkrachtige opneemprofiel (8), en dat het afdichtmiddel (9) wordt gevormd door een gevlochten, ringvormig touw van temperatuurongevoelig materiaal.
2. Het uitlaatgasnabehandelingssamenstel volgens conclusie 1, waarbij het materiaal van het afdichtmiddel (9) anorganisch en onbrandbaar is.
3. Het uitlaatgasnabehandelingssamenstel volgens conclusie 1 of 2, waarbij het afdichtmiddel (9) is gevormd door silica-touwpakking.
4. Het uitlaatgasnabehandelingssamenstel volgens een der voorgaande conclusies, waarbij de patroon (4) is voorzien van een groef (10) en het veerkrachtige opneemprofiel (8) in de groef (10) is gepositioneerd.
5. Het uitlaatgasnabehandelingssamenstel volgens conclusie 4, waarbij de groef (10) is aangebracht in de dieseloxidatiekatalysator (3).
6. Het uitlaatgasnabehandelingssamenstel volgens een der voorgaande conclusies, waarbij de metalen persing (5A) 1s samengesteld uit drie gelijke delen (5A1, 5A2, 5A3).
7. Het uitlaatgasnabehandelingssamenstel volgens een der voorgaande conclusies, waarbij het dieseldeeltjesfilter (2) en de dieseloxidatiekatalysator (3) losneembaar met elkaar zijn verbonden.
