  "textContent": "In order to make the occurring idle stroke as small as possible in a master cylinder, in particular for a coupling, actuation or braking system of a vehicle, comprising a cylinder housing with a piston bore, a piston arranged in the piston bore with a front face facing a cylinder chamber and with at least one replenishing opening leading from a piston lateral surface through a piston wall to the cylinder chamber at a distance from the front face, which in a pressure equalization position of the piston adjoins a replenishing space, so that in the pressure equalization position hydraulic medium can flow back into the cylinder chamber for pressure equalization, and an inner sealing element arranged between the housing and the piston in the region of the piston bore and delimiting the cylinder chamber, it is proposed that the replenishing space between the sealing element and the piston lateral surface is arranged on a side of a sealing lip of the sealing element facing away from the cylinder chamber.",
