MODULAR ELECTRO-HYDRAULIC MULTIWAY VALVE EMPLOYING NOVEL COMBINED SLIDE VALVE AND MINISO CV

摘要

A modular electro-hydraulic multiway valve employing novel combined slide valve and MINISO CV, comprising a group of one combined three-way slide valve main stage (1-1-0) and a group of two MINISO CV valves main stage (2-1-1-0) with a cartridge valve seat having oil recharging and multi-pressure control functions both used to control two reversible controlled chambers of a double-acting hydraulic cylinder or hydraulic motor; the electro-hydraulic multiway valve can be applied in the fields of mobile hydraulics (MH) and industrial hydraulics (IH), applied to machinery, apparatus, and engineering consisting of electro-hydraulic control loops, and to scenarios where special requirements are imposed on environment or scenarios for special purposes. The present invention constructs a novel product solution in compliance with the new and diversified requirements of mobile machinery for hydraulic technology by using modular assembly and an open style according to user needs.
