Abstract (en)

[origin: WO2005033508A1] The invention relates to a two-cylinder high-density matter pump which is used to continuously deliver items, especially concrete. Said high-density matter pump comprises two delivery cylinders which transport the high-density matter from the filling tank into a delivery pipe. A pipe junction is provided with a cross-section which narrows from one of the inlets associated with one of the cylinders to an outlet associated with the delivery pipe. The outlet is joined to the delivery pipe on all of the cross-sections in all positions of at least one delivery cylinder. According to the invention, an arrangement of bearings (20) and a control disk (15) which is rigidly connected thereto are associated with the pipe junctions (11) on the side thereof oriented towards the cylinders (3, 5). The control disk (15) comprises a suction opening (23) which is adjacent to the inlet (21) of the pipe junction (11), the suction opening being arranged at a sufficient distance from the inlet (21) in order to completely cover one opening of one of the delivery cylinders (3, 5). The invention also relates to a method which is used to control said high-density matter pump with a continuous flow rate.
