ELECTRIC PUMP UNIT

摘要

FIELD: mechanical engineering; source of hydraulic energy. SUBSTANCE: electric pump unit has drive motor mounted on shaft. Output end of shaft is made in form of eccentric on which radial piston pump is fitted. Operating cylinders of pump are made in form of monoblock accommodating pistons and valves and furnished with mounting collar by means of which monoblock is installed in electric motor housing. Pistons and valves are arranged coaxially. Circular groove made on outer surface of monoblock is provided with sealing rings located at both sides of groove. Valves are spring-loaded and are installed for engagement with travel stops arranged in delivery chambers communicating through circular groove. EFFECT: simplified design, reduced overall dimensions, increased efficiency and enhanced reliability. 1 dwg
