FIELD: distributing pneumatic equipment. SUBSTANCE: use is made in multi-pass self-adjusting proportional distributing valve of load feedback to create outlet pressures of working fluid proportional to pressures of control fluid. Some versions propose programmed valve for creating different load outlet pressures which are selected before or in course of operation. When no flow escapes from distributing valve, it takes neutral position. EFFECT: enhanced efficiency. 15 cl, 4 dwg
