Abstract (en)
[origin: WO2018145795A1] The invention relates to an oil-free vacuum pump for evacuating gaseous media, comprising: an electric motor (4) which drives a shaft (3); a pump housing (1) having a pump chamber (10), as well as an inlet (15) and an outlet (16); a prismatic displacement piston (2) which is accommodated in the pump chamber (10) such that it is bidirectionally active and can be moved on a reciprocal working section; and at least one pressure valve (20) which releases an outflow of a gaseous medium out of the pump chamber (10) through the outlet (16) and blocks an inflow into the pump chamber (10). The displacement piston (2) has a slot (23) into which a drive force of the shaft (3) is introduced via a crankpin (33) by means of a rolling bearing (31).
