摘要： An apparatus for conveying thick matter has a drive cylinder for receiving hydraulic fluid, a drive piston, which is arranged in the drive cylinder, a conveying cylinder for receiving thick matter, a conveying piston, which is arranged in the conveying cylinder, and a piston rod, which is fastened to the drive piston for coupling motion together with the conveying piston. The drive cylinder has a rod-side opening for applying pressure to a rod side of the drive piston by way of hydraulic fluid and a crown-side opening for applying pressure to a crown side of the drive piston facing away from the rod side by the hydraulic fluid. A drive pump is designed to generate a drive volume flow having a drive pressure of hydraulic fluid for moving the drive piston. A pump connection is designed for variable connection of the drive pump to the rod-side opening or the crown-side opening for the flow of hydraulic fluid. A sensor is designed for automatic detection of whether the pump connection is connected to the rod-side opening or the crown-side opening. A control unit controls the apparatus in a rod-side operating mode, when the rod-side pump connection is detected, and in a crown-side operating mode, when the crown-side pump connection is detected.

摘要： A valveless, positive displacement metering pump is provided by the invention. Such a pump includes a housing, a working chamber within the housing, a piston within the working chamber, the piston including a duct defined by a portion of its outer surface, one or more inflow ports communicating with the working chamber, one or more outflow ports communicating with the working chamber, and a drive cylinder for simultaneously rotating the piston and causing it to move in back and forth strokes within the working chamber. The housing is rotatable with respect to the piston to adjust the timing of the fluid communication between the duct and the inflow and outflow ports, respectively. Such adjustments in timing allow the flow rate of the pump to be fine tuned, and allow each port to experience a partial suction as well as a partial discharge. A method for adjusting the flow rate of a valveless, positive displacement metering pump is also provided which includes adjusting the phases at which the piston duct communicates with each of the ports of the pump.

摘要： When a valve-controlled pump is to produce either vacuum or pressure at a pump outlet 9 as a function of its direction of rotation it is necessary that a 3/2-way valve be switched as a function of the direction of rotation of the motor of the pump. In accordance with the invention this is effected by a direction detection device on the motor (1) which is coupled with the motor for the control of the 3/2-way valve. The direction detection device is formed in the manner that the motor housing of the motor (1) is mounted for rotation and is provided at its end with a structural part (11) having a control kidney (10) which is movable over a control surface (7). Since the motor housing must take up the counter moment when the motor is rotating, the control kidney (10) shifts upon the starting of the motor (1) into one of its two end positions depending on the direction of rotation of the motor (1), thereby causing the pump outlet (9) to be connected alternatively to pressure or vacuum.

摘要： A hydraulic pump assembly including a first pump, a second pump, a shaft, and fluid lines is disclosed. The first pump includes a first piston assembly. The second pump including a second piston assembly. Each piston assembly of the first and second pumps includes a cylinder and a piston slidably disposed in the cylinder. The shaft connects the first pump to the second pump and is configured to displace the pistons within the cylinders of the first and second piston assemblies. The fluid lines fluidly couple the first piston assembly with the second piston assembly to form paired piston assemblies. The first piston assembly is phase shifted from the second piston assembly.
