摘要: A piston pump for a hydraulic brake system for a vehicle with a slip control system. For economical production, the piston pump includes a piston as a composites part with a core of steel that is surrounded by a lubricant jacket of plastic. By way of example, the lubricant jacket is applied to the core by spray-coating, or is pressed onto the core or slipped onto the core. The lubricant jacket economizes by dispensing with expensive post-machining of the piston surface by grinding, for instance, and improves the sliding properties of the piston.
