With the valve body 22 lifted off the sealing seat 21 there is a flow connection between the cooler or. Inside and outside air.
  • a pressure piece 36 is movement-locked added, the other into a chamber 39 in the outer part 12 protrudes and a roller or roller holder 37 has.
  • this receptacle 37 of the pressure piece 36 is one Roller or roller 38 is freely rotatable or inserted.
  • the roller 38 is at least partially within the horizontal cylindrical chamber 39 here, which at its open end using an easily removable Coupling piece 61, on which, for example, to the engine leading hose 62 is attached, pressure-tight sealable is.
  • a piston 46 is in the cylinder chamber 39 Direction of the double arrow A and thus perpendicular to the movement of the pressure piece 36 can be moved back and forth according to double arrow B. guided.
  • a switching spring 49 (Fig. 2A) provided between the coupling piece 61 and the opposite end of the piston 46. That facing away from the coupling piece 61 End 63 of the piston 46 is in a blind hole 64 at other end of the handle 13 out. The smaller diameter End of the piston 46 is surrounded by a compression spring 65 which is supported at the bottom of the blind hole 64 at the other end.
  • the Piston 46 has a pressure element 36 facing one Run-up slope 48 on which the roller 38 of the pressure piece 36 is applied. Opposite the run-up slope 48 is the piston 46 provided with two recesses 51, each in a role or roller 50 is inserted freely rotatable, which rollers 50 rolling against the inner wall of the chamber 39.
  • the operation of the control of the pressure relief valve assembly 11 of the cap 10 is as follows: Coupling piece 61 with a vacuum line to Hose 62 representing engine compartment in the cylinder chamber 39 the handle 13 of the cap 10 is engaged, the Switch spring 49 mechanically biased so that it starts 1 pushes the piston 46 inwards. As a result, the ramp 48 and the roller 38 Thrust piece 36 moved in the direction of arrow B1 (downward), so that the pressure relief valve spring 28 is biased. On in this way the valve body 22 receives an increased Opening pressure.
  • the pressure relief valve spring 28 again tense, so that a, for example, 2.0 bar increased opening pressure for the valve body 22 results.
  • the valve body 22 can be caused by the accumulated heat resulting higher due to the stopped engine Withstand cooler or tank pressure.
  • the coupling pin 82 is in one in the bore 86 the handle 13 held bearing sleeve 88 up and down guided and on its motion-resistant collar by one Compression spring 85 is urged toward the bore ring 83.
