Definitions
- the vacuum valve body is expediently provided at a distance from the pressure valve body at the bottom of the inner cover part.
- Fig. 2 is an inside view of the inner lid part without
- Closure element 17 and grip element 18 are canceled. If the engine is switched off, the temperature, which is passed on to the membrane capsule 50 via the sensor rod 54, further increases due to the accumulation of heat in the container, which causes the membrane capsule 50 to expand further in the axial direction. As a result of the diaphragm capsule 50 resting against the fingers 25 of the grip element 18, the diaphragm capsule 50 expands axially in the direction according to arrow B1 downward against the action of the compression spring 44 and acts on the compression ring 48 and the axial compression sleeve 46, so that the opening pressure for the overpressure valve body 12 is brought to a higher value of, for example, 2.0 bar by the increased biasing force of the compression spring 44. Even in this state, the idle connection between the grip element 18 and the closure element 17 is retained, since the locking plate 27 remains in its uppermost position. The starting position according to FIG. 1 is only reached again after complete cooling.
