Definitions
- the invention relates to a vacuum can according to the preamble of independent claim 1.
- a vacuum box in the form of a pneumatic switching element is known from DE 196 23 961 A1.
- This is connected to a vacuum source and has a pressure chamber in which an actuator which can be displaced against the force of a spring element by a vacuum is arranged.
- This actuator is connected to an actuating device which is led out of the pressure chamber.
- the spring element is arranged outside the pressure chamber and engages the actuating device or can be fastened to a joint arranged outside.
- a guidance of the push rod over the spring cannot be realized with this construction.
- the push rod can tilt and thus rub the membrane of the vacuum box on the housing or come to rest, which can damage the membrane.
- the membrane can be rubbed, which can lead to failure of the vacuum box. This leads to inaccuracies in the transfer of the vacuum to an element to be actuated.
- FIG 3 shows a vacuum can with an additional expansion element 24.
- expansion elements are also known under the name wax thermostat and lead
- the vacuum box shown in FIG. 4 can also drive a crank, as is customary for vacuum drives of rotary valves, for example on intake systems of internal combustion engines, without the need for an additional joint
- the push rod is necessary. It is advantageous that the leadership is the most distant Point from the crank mechanism, this minimizes the angular deflection of the push rod.
