| description | The pump unit (13) has an axially movable pump piston (28) arranged in a cylinder chamber (18) and coupled with a plunger (32). A roller shoe (34) is coupled with the plunger. A roller (36) is rotatably mounted in the roller shoe to indirectly support the pump piston for driving fluid to a fluid pump (10). A spring assembly (42) is axially arranged between the plunger and the roller shoe to limit force transferred by the roller shoe on the pump piston according to a predetermined maximum discharge pressure of the fluid pump. An independent claim is also included for a fluid pump for conveying fluid.
