In the proposed apparatus, each plunger shaped as a truncated pyramid is provided with grooves extending along the edges of the smaller base of the pyramid and forming circular passages round a working chamber in the gaps between adjacent plungers. The cross section of each passsge is defined by smooth curves, the passages being filled with a sealing material. In each gap between plungers, there may be provided a plurality of parallel passages which, in some cases, are filled with materials of different compressibility.
