Title: Solenoid valve
Inventor: MARSDEN JOHN THOMAS
IPC: H01F7/16
Filed: 1986-06-27
Abstract: A guide for the armature of a solenoid valve is provided by a winding former (18) moulded from plastics material. The armature (22) is axially movable between a first position closing a fluid port (36). A magnetic circuit for the solenoid is formed by a pole piece (23) coaxial with the armature and carrying the first port (24), a field can (44) coaxial with the armature and annular field members (46). The field can (44) is contained in valve body (12) also moulded from plastics material. The winding (14), field can (44), pole piece (23) and field members (46) are accurately positioned and assembled prior to injection moulding of the former and valve body. This enables the bore in which the armature slides to be precisely dimensioned and to facilitate final assembly. <IMAGE>
