Abstract

To provide a hydraulic master cylinder with inlet ports and outlet ports arranged in an angle to each other wherein the outlet ports can be on either side of the housing without the need of two different casts, the master cylinder according to the invention is equipped with either two sets of protrusions adapted to be machined into inlet ports or two sets of protrusions adapted to be machined into outlet ports. The two sets of identical protrusions are arranged symmetrically with respect to the one set of different protrusions. Thus, depending on the desired side of the outlet ports, only one set of the two sets of identical protrusions is machined while the other set remains an unmachined accumulation of material.
