FIELD: hydraulic controlling gears. SUBSTANCE: invention refers to driving cylindrical electromagnets. Electromagnet has magnetic body 1, cylindrical sleeve 3, anchor 4 moving in sleeve 3, flange 2 located in body and sleeve. Ferromagnetic sleeve 3 is divided into two parts by trapezoidal nonmagnetic ring 6, working butt of anchor has circular trapezoidal collar 7 that interacts with groove 8 of similar profile in flange and with sleeve. Side surface of anchor has flat 11 on side of working clearance 11 and frame 1 is formed by flange 2, sleeve 3 and washer 10. EFFECT: increased reliability and diminished energy consumption. 4 dwg
