Abstract
A thick matter pump includes a hydraulically-driven two-cylinder piston-pump configured to generate a thick matter delivery pressure. The thick matter pump also includes a hydraulic pump configured to apply hydraulic fluid to the two-cylinder piston-pump via a drive line. The hydraulic pump includes a pressure regulator that is adjustable to a target value of pressure of the hydraulic fluid for limiting the thick matter delivery pressure, and the thick matter delivery pressure is adjustably limited. The pressure of the hydraulic fluid is limited in the drive line, via an adjustable pressure-limiting valve, to an adjustable maximum pressure. The target pressure of the pressure regulator and the maximum pressure of the hydraulic fluid are adjustable through a joint adjusting element.
