PCT No. PCT/EP93/01840 Sec. 371 Date Jul. 15, 1996 Sec. 102(e) Date Jul. 15, 1996 PCT Filed Jul. 13, 1993 PCT Pub. No. WO95/02764 PCT Pub. Date Jan. 26, 1995A pump system for producing high and exactly controllable pressure levels includes a piston pump which has a piston (32) connecting to a spindle shaft (22), a spindle nut (44) on said spindle shaft, a cylinder block (34) having a bore (36) for receiving said piston, a mechanism (14, 16, 26) for imparting relative rotational and axial motions between said piston and said cylinder block including a device for causing relative rotary motion of said spindle and spindle nut. A helical spring (46) or other resilient element is connected between said cylinder block (34) and said spindle nut (44) to compensate the reaction force generated by a pressurized fluid sample in said cylinder bore (36) when put under compresion. A flexible element (30) is connected between the piston (32) and the spindle shaft (22) to compensate for any axial misalignment of the piston and the cylinder bore. Methods for operating such a system under adiabatic, isothermal, isobaric and isochoric conditions are described. (FIG. 3).
