1. Master cylinder, in particular for a clutch, actuating or brake system of a vehicle, comprising a cylinder housing with a piston bore, a piston arranged in the piston bore and having an end side facing a cylinder chamber and at least one afterflow opening leading from a piston skirt surface through a piston wall to the cylinder chamber at a distance from the end side, said opening adjoining an afterflow space in a pressure equalization position of the piston so that in the pressure equalization position hydraulic medium can run on into the cylinder chamber in order to equalize the pressure, and an inner sealing element arranged between the housing and the piston in the area of the piston bore and limiting the cylinder chamber, the sealing element being insertable into the cylinder housing from an outer opening thereof and an insert fixing the sealing element in place is insertable into the cylinder housing. |
