Roller plungers assembly for radial piston pump for conveying fluid, has plunger, which is disposed and adapted to move in direction of plunger axis

摘要

The roller plungers assembly (30) is designed to indirectly support a piston pump(24) to drive a radial piston pump (10) formed on a drive shaft (16), where a cylindrical plunger (32) is provided with a plunger longitudinal axis (L). The plunger is disposed and adapted to move in the direction of the plunger axis, where the plunger has a roller (36), which is rotatably supported for restart of the drive shaft in an indirect manner. An independent claim is also included for a radial piston pump for conveying fluid.
