Abstract

In a pump with two piston-cylinder units, each piston (6), which can be moved backwards and forwards by a linear drive via a clutch (20) and a piston rod (7), can be displaced backwards and forwards in a cylinder (5) having an inlet valve (2) and an outlet valve (3). To adapt the piston-cylinder units to the particular requirement, irrespective of the appropriate design and power of the linear drive in the particular case, an inner body (22) of an axial permanent- magnet clutch (20) on the common piston rod (7) is arranged inside and an outer body (21) outside a split tube (11) of nonmagnetic material. The split tube (11) for its part is connected fluid tightly to each cylinder (5). A leakage-fluid relief line (23) is provided which connects the spaces in the split tube (11), which are situated on both sides of the inner body (22).
