Abstract
Radial piston pump and a method of assembly of the radial pump in particular radial piston pump, including a drive shaft having an eccentric and at least one piston-and-working-chamber combination, wherein the piston-and-working-chamber combination comprises a cylinder bore and a piston, wherein the cylinder bore has a fluid outlet duct, the cylinder bore is closed with a cover, wherein the cover is received in a cover receptacle bore, the cylinder bore has a longitudinal axis, and the cover receptacle bore has a longitudinal axis, wherein the longitudinal axis of the cylinder bore and the longitudinal axis of the cover receptacle bore are not congruent, in particular are displaced in parallel.
Claims14
A radial piston pump comprising:
- a drive shaft having at least one piston-and-working-chamber combination, wherein the piston-and-working-chamber combination comprises a cylinder bore and a piston, wherein, the cylinder bore has a fluid outlet duct extending radially through a circumferential outer wall of the cylinder bore, the cylinder bore is closed with a cover, wherein the cover is received in a cover receptacle bore, the cylinder bore has a longitudinal axis, and the cover receptacle bore has a longitudinal axis, and the longitudinal axis of the cylinder bore and the longitudinal axis of the cover receptacle bore are not congruent;
- wherein the radial piston pump includes a fluid inlet duct having an inlet valve;
- wherein the fluid outlet duct has an outlet valve;
- wherein the fluid inlet duct is aligned radially in relation to the drive shaft, and the fluid outlet duct is aligned axially in relation to the drive shaft;
- wherein a step is provided between the cylinder bore and the cover receptacle bore, which step forms a bearing face for a peripheral region of the cover;
- wherein the inlet valve is fastened to the cover by means of at least one securing element.
