Patent ID: 8803645

Claim:
A proportionally acting solenoid comprising: a plastics encapsulation having a fastening flange which is integrally formed thereon and contains first shaped elements which, in interaction with second shaped elements of a housing, permit installation of the solenoid onto the housing and partially into a receiving bore in the housing by pressing the solenoid into the receiving bore along a longitudinal axis of the receiving bore and rotating the solenoid, the first shaped elements and the second shaped elements holding the solenoid on and partially in the housing axially and against rotation by latching preventing the rotational movement, wherein springs which consist of metallic sheet metal take on both axial pretensioning for mounting of the solenoid and resilient latching for holding rotational position, and wherein pretensioning forces of the springs for the mounting of the solenoid and for the latching during the rotation of the solenoid are produced during the installation by integrally formed bevels on the first shaped elements, and wherein a seal seals a radial gap between the solenoid and the housing with a small axial installation force, and wherein the metallic springs are fastened in a clamping manner to at least one of the fastening flange of the proportional solenoid or to the second shaped elements of the housing.
