Abstract: A thick matter pump comprising a conveyance capacity control system. Said thick matter pump comprises a drive motor 50 which is preferably embodied as an internal combustion engine, a hydraulic pump 6 which is preferably embodied as a reversible pump, which has a variable displacement volume V and can be coupled to the driving motor, and two hydraulic cylinders 5, 5′ which are connected to the hydraulic pump 6, can be controlled by the same in a push-pull manner, and are each coupled to a conveyor cylinder 7, 7′ for conveying the thick matter. A regulator for regulating the rotational speed N is associated with the drive motor 50, and a regulating element 18, 20 for regulating the displacement volume V is associated with the hydraulic pump 6. A control module 54 is also provided for regulating the rotational speed N of the motor and the displacement volume V. According to the invention, the control module 54 comprises a final control element 56 for regulating the thick matter conveyance capacity F of the conveyor cylinders 7, 7′, and an electronic control unit 108 which reacts to the position of the final control element 56 and allocates a nominal value to the rotational speed regulator and to the displacement volume regulator 20, in a software-assisted manner. These measures enable improvement of the operational ease of the thick matter pump, and reduction of fuel requirements, noise emission and waste gas emission during practical use.

Abstract: A flow control system for controlling a variable displacement pump including a metering valve in fluid communication with the pump for metering an output of the pump. A regulating valve receives a portion of the output of the pump as a bypass flow at a first pressure, wherein an output of the regulating valve is at an interim pressure. The interim pressure is substantially equal to an average of the first pressure and a low reference pressure. An actuator sets a displacement of the pump by acting on a piston connected to a cam ring of the pump. The actuator receives the interim pressure and, thereby, the output of the variable displacement pump is determined.

Abstract: A rotary reciprocating pumping apparatus is provided with a positive two position adjustment feature which allows the piston stroke to be increased to a maximum and repeatably, automatically, returned to a second calibrated dispensing position. Such rotary reciprocating pump is further provided with an adjustable liquid displacement velocity profile to maintain sufficient velocity of liquid flow at the end of the pump discharge cycle to enable injection of small volumes of liquid through a pump exhaust port, thereby eliminating the inaccurate and time consuming operation of touching off a small volume of liquid as a drop characterizing known rotary reciprocating pumping systems. A stabilizing ring of the cylindrical pump case is flush mounted within a counterbore of a pump mounting plate with one side of the ring directly abutting the bottom of the counterbore and a diametrically opposite side and abutting one or more standoffs to set the axis of the pump case and the pumping chamber at a slight angle in a transverse plane to the axis of the counterbore within the pump mounting plate, thereby modifying the pump piston liquid velocity profile to ensure significant fluid velocity at termination of the pump piston discharge stroke.
