  • inlet valve 140 is connected downstream of inlet line 111 and upstream internal volume V102 of fuel enclosure 102.

  • Helical spring 141 hence urges abutment surface 142 against thrust surface 134.
  • Inlet valve 140 thus follows cap 130, when cap 130 is being unscrewed.
  • Helical spring 141 forms a first operating means adapted to close inlet valve 140 when cap 130 is in a first predetermined position.

  • This first predetermined position can be reached by unscrewing only partially cap 130, say by a predetermined number of turns. Such a first predetermined position ensures that inlet valve 140 will be shut long before the sealing means, like O-ring 137, shoulder 136 and thread 135, loose contact with the inner walls of housing 101. This avoids any significant leak of fuel.

  • filtering device 100 enables an easy access to volume V 0 2 of fuel enclosure 102 and, in particular, to filter unit 103.

  • cap 130 when the user screws cap 130, assembled with filter unit 103, onto the walls of housing 101, cap 130 reaches a second predetermined position where thrust surface 134 reaches abutment surface 142, i.e. where cap 130 comes in contact with inlet valve 140.
  • a second predetermined position also represents an intermediate position, for it lies between the closed position and the open position of cap 130.
  • Thrust surface 134 urges upper flange 143 away from seat 113 against helical spring 141. Thrust surface 134 forms a second operating means adapted to open inlet valve 140 when cap 130 reaches this second predetermined position, thus starting to open inlet valve 140.
