Abstract
A radial piston pump, in particular radial piston compressor, including a drive shaft with an eccentric, and at least one piston/working chamber combination, wherein the piston/working chamber combination includes a working chamber and a piston, wherein the radial piston pump includes at least two piston/working chamber combinations extending radially from the drive shaft, wherein each working chamber is closed with a cover, wherein the radial piston pump is equipped with a housing component with an integrated retaining ring for fixing all of the covers of the radial piston pump.
Claims19
A radial piston pump, comprising:
- a drive shaft having at least one piston/working chamber combination, wherein the at least one piston/working chamber combination includes a working chamber and a piston;
- at least two piston/working chamber combinations extending radially from the drive shaft, wherein each working chamber is closed with a cover;
- and
- a housing component with an integrated retaining ring for fixing all of the covers of the radial piston pump;
- wherein contact faces are provided on the housing component with the integrated retaining ring and on the covers, wherein the contact faces are configured to allow the housing component with the integrated retaining ring to fix the covers;
- wherein the contact faces with respect to and/or of the respective covers are concave/convex;
- wherein curvatures of the covers or of the housing component with the integrated retaining ring are axially aligned with respect to the drive shaft of the radial piston pump and/or transversely aligned with respect thereto;
- wherein the housing component with the integrated retaining ring consists of steel or a steel alloy at least in sections;
- wherein the housing component with the integrated retaining ring includes a main body and locking protrusions that extend radially inward from the main body, wherein the locking protrusions are configured to fix the covers.
