Abstract
1417669 Valves FLUID DEVICES Ltd 2 Nov 1973 [2 Nov 1972] 8576/75 Divided out of Co-pending 50624/74 Heading F2V A magnetically actuated valve (Figs. 1, 2) comprises a slidable armature 1 in a diamagnetic tube 6 sealedly attached to stationary polepieces 2, 3. A steel sleeve 8 with endpieces 9 surrounds the tube and polepiece assembly and also a bobbin 10 with separate windings 11a, 11b on parts of the bobbin interconnected by four webs 12, which retain four sector shaped ceramic radially magnetized machined permanent magnets 13. Series energization of the coils is applied over connector 14 with terminals 15, 16 and earth pin 16, and the coil assembly is removable by detaching retaining nut 17. Integral rectifiers may be inserted in cavities of connector 18 for A.C. operation. On de-energization, the armature 1 is as shown in upper position retained against upper polepieces 2. On D.C. energization of windings 11a, 11b the armature is impelled downwards to the opposite polepiece 3 where it is retained on de-energization. The armature position is reversible by further energization of windings 11a, 11b in reverse polarity and it is then retained against polepiece 2. The polepieces 2, 3 extend from each end into the armature tube 6 and have valve orifices: that of polepiece 2 being a bore 33 in a central projection communicating with a first fluid connection 34 while polepiece 3 has an axial bore containing an, e.g. ferromagnetic coaxial tube 35 whose lower end 36 exceeds the remainder in diameter for an interference fit. The upper end is connected to a fluid connection 37 over transverse bore 38, and the tube is also surrounded within the polepiece by annular duct 39 connected to a fluid connection 40 over transverse bore 41. Armature 1 has a stepped central bore with a rubber valve seat 43 at each end and is radially slotted in its end faces and longitudinally slotted of its periphery, so that connection 40 and annular duct 39 communicate with the space within which the armature moves, and alternatively with connections 34, 37 dependently on the armature position.
