<p>The main brake cylinder (10) has a housing (12) containing at least one pressure piston (16, 18) forming a pressure chamber (20, 22) with the housing, and a control valve device (36, 40) connected to a reservoir (28, 30). There is a guide element (52, 58) on the pressure piston close to the control valve body (42, 44) preventing the piston becoming misaligned in the housing.</p> |
