CYLINDER FOR HYDRAULIC COMPRESSION OF HYDROGEN WITH LIMITED FOAM FORMATION IN THE WORKING FLUID

The invention relates to the field of mechanical engineering, in particular, to hydraulic compression devices, namely compressors in which a liquid and a gaseous medium are simultaneously introduced into a working chamber and can be used for the hydraulic compression of hydrogen. The purpose of the invention is to reduce the gas temperature inside the cylinder and to increase the performance of the hydrogen hydraulic compression device. The cylinder for hydraulic compression of hydrogen includes a hermetically sealed housing (1), the upper part (2) of which contains a branch pipe (3) with a channel (4) for filling and draining the compressed hydrogen, and the lower part (6) of the cylinder has a second branch pipe (7) with a channel (8) and an inlet with a diameter D for filling and draining the working liquid. In the center of the lower part (6) of the housing (1) in the interior of the cylinder (5) there is a protrusion (9) with a height of H. The lateral wall of the protrusion (9) and the inner wall of the lower part (6) of the housing (1) form an annular channel (10) with a width of L. The channel (8) of the branch pipe (7) is located tangentially in relation to the lateral wall of the housing (1), and its axis line is oriented perpendicular to the cross-sectional plane of the annular channel (10), in addition, the inner wall of the branch tube (7) channel (8) is tangentially aligned with the inner wall of the annular channel (10).
