Abstract:
The invention relates to a metering pump having a hydraulic drive ( 12 ) for supplying a hydraulic fluid under pressure. The metering pump furthermore comprises a housing ( 2 ) and an oscillating piston ( 3 ), which is accommodated in the housing ( 2 ) in such a way that at least a first and a second hydraulic chamber ( 9 - 1, 9 - 2 ) and a first ( 6 - 1 ) and a second delivery chamber ( 6 - 2 ) are formed, wherein the oscillating piston ( 3 ) has at least a first driving surface ( 10 - 1 ) in the first hydraulic chamber ( 9 - 1 ) and at least a second driving surface ( 10 - 2 ) in the second hydraulic chamber ( 9 - 2 ), and the hydraulic chambers ( 9 - 1, 9 - 2 ) communicate with the hydraulic drive, thus enabling the oscillating piston ( 3 ) to be moved backward and forward between a first and a second position by the hydraulic fluid, wherein, during the movement from the first to the second position, the volume of the first delivery chamber ( 6 - 1 ) is enlarged and the volume of the second delivery chamber ( 6 - 2 ) is reduced and, during the movement from the second to the first position, the volume of the second delivery chamber ( 6 - 2 ) is enlarged and the volume of the first delivery chamber ( 6 - 1 ) is reduced. The invention furthermore relates to a metering system for mixing two fluids and a metering system for metering at least one fluid.

Claim (Index 1):
A metering pump having\n a hydraulic drive ( 12 ) for supplying a hydraulic fluid under pressure, a housing ( 2 ), an oscillating piston ( 3 ), which is accommodated in the housing ( 2 ) in such a way that at least a first and a second hydraulic chamber ( 9 - 1 ,  9 - 2 ) and a first ( 6 - 1 ) and a second delivery chamber ( 6 - 2 ) are formed, and an adjusting device, which is coupled to the oscillating piston ( 3 ) in such a way that the movement of the oscillating piston ( 3 ) can be limited in such a way that different minimum and/or maximum volumes can be set for at least one of the delivery chambers ( 6 - 1 ,  6 - 2 ), wherein the oscillating piston ( 3 ) has at least a first driving surface ( 10 - 1 ) in the first hydraulic chamber ( 9 - 1 ) and at least a second driving surface ( 10 - 2 ) in the second hydraulic chamber ( 9 - 2 ), and the hydraulic chambers ( 9 - 1 ,  9 - 2 ) communicate with the hydraulic drive ( 12 ) thus enabling the oscillating piston ( 3 ) to be moved backward and forward between a first and a second position by the hydraulic fluid, wherein, during the movement from the first to the second position, the volume of the first delivery chamber ( 6 - 1 ) is enlarged and the volume of the second delivery chamber ( 6 - 2 ) is reduced and, during the movement from the second to the first position, the volume of the second delivery chamber ( 6 - 2 ) is enlarged and the volume of the first delivery chamber ( 6 - 1 ) is reduced and wherein the adjusting device comprises at least one stop piston ( 23 - 1 .  23 - 2 ), which limits the space in the delivery chamber ( 6 - 1 ,  6 - 2 ) which is assigned to the stop piston ( 23 - 1 ,  23 - 2 ).
