    • A device (31) for injecting an incompressible, pressurized liquid into a container (18) made of a thermoplastic material so as to shape the container (18), includes: a pipe (30) for supplying the liquid, which is to connect a liquid source (40) to the container (18); pumping elements (42) for causing the liquid to flow in the supply pipe (30) toward the container (18) at a first pressure (P1); and compression elements (44) for temporarily raising the pressure of the liquid contained in the container (18) to a second pressure (P2) that is greater than the first pressure (P1), wherein the compression elements (44) are formed by a work chamber (48), whose volume is variable, and which is connected only to the supply pipe (30) between the pumping elements (42) and the container (18).
    • 一种用于将不可压缩的加压液体喷射到由热塑性材料制成的容器(18)中以使容器(18)成形的装置(31)包括:用于供应液体的管道(30),其用于连接 液体源(40)到容器(18); 用于使液体以第一压力(P1)朝向容器(18)流动的泵送元件(42); 以及用于将容纳在容器(18)中的液体的压力临时提高到大于第一压力(P1)的第二压力(P2)的压缩元件(44),其中压缩元件(44)由 工作室(48),其体积可变,并且仅与泵送元件(42)和容器(18)之间的供应管(30)连接。
