The free shaft end has a pin-shaped bent part 4, on which a rolling bearing 6 is placed, and depending on the bending ratio of the bent part, a vacuum can be applied directly via the outer race 8 of the rolling bearing 6. A vacuum pump, characterized in that it is adapted to produce a stroke movement of a piston member 10 of the pump. 2 The piston member 10 is a diaphragm, and the diaphragm acts on the pressure plate 9 on the drive side and on the spring member 17 acting against the force on the drive side on the pump working chamber side. A vacuum pump according to scope 1. 3 The cover 13 of the generator 1 is the inlet valve 14 of the pump
and an outlet valve 15, and further comprising an outer edge of the diaphragm being clamped between the casing 3 of the generator 1 and the cover 13. 4. Any one of claims 1 to 3 of the utility model registration claim, in which the transmission engagement between the drive device and the piston member 10 is automatically released in response to vacuum pressure. Vacuum pump according to item 1.
