ABSTRACT:
An apparatus for producing high pressure comprises a multi-die system (1). Each die (2) is made up of two cooperating parts arranged along a longitudinal centerline (3) of the die (2), one part being a working body (4), the other being a base member (8). The working body (4) is also made up of two parts in the direction essentially perpendicular to the longitudinal centerline (3) of the die (2), the parts being a central insert (21) and an encircling ring (22) both arranged coaxially and capable of relative displacement towards a test sample (7). The surface area of an end (23) of the central insert (21) of the working body (4) approximates to or less (in this case less) than the surface area of the central portion (18) of an end (11) of the working body (4). An end (5) of the working body (4) is arranged for direct cooperation with a solid medium (6) which is plastic under pressure and serves to surround a sample (7) being tested. An end (9) of the base member (8) faces a die driving means (10) common to all dies. The space between other opposing ends (11 and 12) of the working body (4) and the base member (8) is filled with a solid medium (13) plastic under pressure. The surfaces of the ends (11) and (12) are provided with identical annular grooves (14 and 15) respectively, the grooves being filled with a solid medium (20) plastic under pressure.
