Abstract

Invention m. used in machine tools. The purpose of the invention is to reduce leakage from a power source through a hydraulic system. For this, the distribution device is made in the form of three controlled check valves (ASD) 11, 13 and 14, the control cavities 15, 16 and 17 communicate with the power supply 10 and drain 12 via a three-way reversing valve () 19 control ( The input of the CRM 14 is in communication with the rod cavity 3 of the hydraulic cylinder, the output of the CRM 15 is with the hydraulic panel 6 and the entrance of the CRM 13, the output of which is connected with the drain. In addition, the outputs of the CRM 11 and 14 are connected with each other and with the drain position P 20, and the pressure valve 5 is installed in the communication line of the cavities 2 and 3 of the hydraulic cylinders 1 and e of cavity 18 communicates with the control 19. The hydraulic system P provides fast feed mode, two modes of cutting feed mode and fast retraction. 1 yl. SS (L ff with from about from JV 4ib ff
