ABSTRACT:
A solenoid valve assembly in which the solenoid and valve are axially fitted together. The solenoid comprises a cylindrical housing having an axial slot running along its entire length to allow the housing to be resiliently circumferentially expanded. The valve body has a cylindrical axial surface over which an axial end portion of the housing is fitted. Just beyond this cylindrical axial surface is a narrow groove. The cylindrical housing of the solenoid is provided with preformed stakes in its end edge which fit into this narrow groove to retain the solenoid end valve together in assembly. The invention is particularly advantageous where there is a limited axial length for the cylindrical housing of the solenoid to fit onto the valve body. The invention provides adequate retention in assembly, a sufficient area for magnetic flux that passes between the solenoid housing and the valve body, and the ability to easily disassemble the solenoid from the valve when such disassembly is desired.
