摘要:
The invention concerns a piston pump (10) for a vehicle antiskid hydraulic brake system. The invention aims at the economical production of said pump piston (20, 22). To this end, the piston is produced from a part obtained by forming (20) and a closure plug (22) driven in by a pin (42) into said part (20). The advantage of the invention lies in the fact that the piston (20, 22) can be produced without elimination of material, therefore quickly and economically, in the form of a piece obtained for example by extrusion.
