BRAKE PRESSURE GENERATOR

The brake pressure generator according to the invention comprises a hydraulic block having a brake cylinder bore . A piston with a pressure side , which projects into the brake cylinder bore , and with a coupling side , for coupling the piston to an actuating rod , extends along a piston longitudinal axis between the pressure side and the coupling side . A receiving element comprises a connecting section and a sliding guide . A guide rod fastened to the hydraulic block and offset and oriented parallel to the piston is at least partially engaged around by the sliding guide , with the result that the piston can slide along the guide rod during an axial movement. Between the coupling side and the connecting section , an axial form fit acts, which at least primarily prevents the receiving element from being released from the piston in the axial direction . In addition, a circular form fit acts between the coupling side and the connecting section , which at least primarily prevents a rotation of the receiving element relative to the piston . The invention also relates to a corresponding piston arrangement .
