Abstract

hydraulic systems. SUBSTANCE: device functions to continuously control volume flow to and from user by means of two proportionally operating four-line, two-position electromagnetic valves each provided with seat valve members and by means of two seat-type shutoff valves; free running is attained at fourth position. Electromagnetic valves are similar in design and each is mounted on volume flow path running to and from user; each connection for user is tightly blocked by seat member of electromagnetic valve and by shutoff valve. Each electromagnetic valve has main control and pre-control sections using servo control type of interaction and dispensing with separate oil supply. EFFECT: provision for continuous and fast-response control of high hydraulic power. 20 cl, 10 dwg
