Abstract

Piston vacuum pump, especially for motor vehicles, with a piston that can be propelled by a pusher against the force of a recovery spring, characterized in that the piston has a hole centered to house the fixing nut or the screw of the pusher, and in that the termination of the upper working space is formed by a flat sheet metal lid, the edge of which is folded back on itself, at least in some places, together with recesses of the housing.
