FIELD: power engineering. SUBSTANCE: proposed set 300 with variable compression ratio contains great number of two-sided pistons 330, 332, rotating member, for instance, flywheel 322 or articulated member providing zero travel and connected to intermediate arm 310 and made with shape to provide displacement relative to intermediate arm 310 along axis of rotation of rotating member 322. Travel of rotating member 322 relative to intermediate arm 310 changes compression ratio of piston set 330. Intermediate arm 310 is connected to each two-sided piston 330, 332, approximately in center of each piston 330, 332. Travel of rotating member 322 relative to intermediate arm 310 changes compression ratio and displacement of each two- sided piston 330, 332. Invention makes it possible to reduced loads on drive system and to provide higher compression ratio. EFFECT: increased efficiency and improved protection against failures, especially in case of choking at delivery stroke. 27 cl, 32 dwg
