摘要

The pump (10) has a conveying cylinder (12) which has a material chamber (14) with a material outlet (22). Another material chamber (16) is connected with the former material chamber by a valve and has a cylinder extension (20) connected with the latter material chamber by another valve (40). A driving element is provided which has a piston rod (36) projecting into the former material chamber. The piston rod is firmly connected with a conveying piston (24). Another piston rod (38) projects into the latter material chamber that carries a scoop piston (42).
