Abstract
1,147,204. Valves. Z. OLSEN. 12 April, 1966, No. 16039/66. Heading F2V. [Also in Divisions G3 and H1] In an electrohydraulic servo-valve (see Divisions G2-G3) a cantilever 80 movable about a torsion shaft 83 co-operates with a nozzle 76 to control the flow into chamber 68. The cantilever is connected to the armature 89 of an electromagnet having coils 85, 86 connected in series, parallel or in series opposition. The coils are encased at 91 and surround a core 90. The assembly is located within a permanently magnetic housing 84, the end of which supports a polepiece 92 and the torsion shaft and collects magnetic debris. The nozzle is supplied through a pressure regulator (Fig. 3A) having a filter 74 and a spring-loaded piston 94. The pressure in chamber 68 positions a spool 69 loaded by a spring or, as shown, by pressure at 78. The spool slides in a sleeve 67 supported in an outer sleeve 66 having sealing flanges 66a; and controls flow between inlet P, work ports C 1 , C 2 and exhaust chambers R. The core can have a cylindrical extension surrounding the permanent magnet. Alternatively, a semi-cylindrical permanent magnet forms half of the outer limb of an E-section core.
