Definitions
- the plunger 142 has a thickened portion 160, which in the FIGS. 5A to 5C also shown in sections trough-shaped support member 84 passes through.
- the potential energy can be released by the coil spring 98 within a short time and released via the contact element 100 to the plunger 180.
- the plunger 180 thus acts as a power transmitting member to deliver the energy released from the coil spring 98 to the valve door 190 and to apply an opening force thereto.
- This opening force causes the valve flap 190 is pivoted about the axis 192 and thus releases the valve seat 66 abruptly.
- foreign air present in the external air space 60 can enter the suction chamber 102 at atmospheric pressure, which leads to an intensive pressure surge on the filter 34.
Claims (15)
