The invention relates to a piston pump for thick matter, in particular for high-solids sewage sludge, coal sludge and concrete. The piston pump has at least one delivery cylinder (16) which contains a motor-driven or hydraulically driven delivery piston (20) and which has an orifice (12) which communicates alternately with the interior of a material feed container (10) and with a pressure delivery line (30) in a slide-controlled manner in accordance with the movement of the delivery piston (20). In order to significantly increase the degree of filling of the at least one delivery cylinder (16), an annular nozzle (32) opening into the delivery cylinder (16) in the region of the orifice (12) is provided, and this annular nozzle (32) is connected to an external pressure line (34) to which a lubricant can be admitted.
L'invention concerne une pompe à piston pour substances épaisses, en particulier des boues de clarification riches en solides, des suspensions de charbon et du béton. La pompe à piston présente au moins un piston de transport (20) entraîné par moteur ou hydrauliquement et contenant un cylindre de transport (16) qui présente une ouverture d'embouchure (12) qui, en fonction du déplacement du piston de transport (20), communique en alternance sous la commande d'un coulisseau avec l'intérieur d'un récipient (10) de sortie de matière et un conduit (30) de transport sous pression. Pour augmenter de manière significative le degré de remplissage dudit ou desdits cylindres de transport (16), on prévoit un ajutage annulaire (32) qui débouche dans la zone de l'ouverture d'embouchure (12) dans le cylindre de transport (16) et qui est raccordé à un conduit externe sous pression (34) alimenté en agent lubrifiant.
