DEVICE FOR CREATING HIGH PRESSURE Russian patent published in 1996 - IPC

FIELD: chemical engineering. SUBSTANCE: device has housing with spherical cavity in which flexible shell of spherical shape is disposed. Housing and shell consist of two parts. Parts of shell are fixed on corresponding parts of housing forming the chamber for primary pressure with two isolated cavities. Punches are located inside parts of shell. Their external parts have the shape of truncated pyramids having spherical larger base and are disposed with spaces between lateral surfaces in which flexible members are located. Internal parts of punches contacting with external ones are also disposed with spaces between lateral surfaces in which deformed linings are located. Chamber of high pressure is formed by planes of internal parts turned to center of spherical shell. Gaps between external parts of punches are thickened with shields. Internal parts are equipped with means for their holding in desired position relative to each other adapted for installation-removal of all internal parts and material at the same time. The innovation concerns high and superhigh pressure arousing chemical or physical modification of substances. EFFECT: simpler and faster assembly-disassembly, enhanced device efficiency, enhanced reproducibility of material compression conditions, ensured possibility to mechanize and automatize the assembly-disassembly work. 15 cl, 23 dwg
