Abstract

1. Rotary piston pump for conveying material interspersed with foreign bodies, such as liquid manure or the like, in which two rotary pistons rolling on one another and rotating in opposition are secured in a housing on two mutually parallel shafts, the rotary pistons comprising respectively a carrier body and a resilient jacket surrounding the periphery thereof, characterized in that adjustment pistons (62) which can be acted upon by pressure medium are arranged between the carrier body (16) and the jacket (18).
