<p>The pump comprises at least one pump element (18) that has a pump piston (20) which is at least indirectly driven by a rotating drive shaft (14) during a reciprocating motion, said drive shaft (14) including at least one cam (16). The pump further comprises a pump housing (10), inside which the drive shaft (14) is arranged and into which liquid medium is delivered via a supply port (66) and from which liquid medium is discharged via a discharge port (68). The pump housing (10) and the at least one cam (16) of the drive shaft (14) delimit a chamber (64) inside the pump housing (10), said chamber (64), into which the supply port (66) and the discharge port (68) run, extending along the periphery of the at least one cam (16).</p> |
