Abstract
A proportionally acting solenoid with a plastics encapsulation having a fastening flange which is integrally formed thereon and contains shaped elements which permit installation of the solenoid onto the housing by axial pressing in, rotation and rotary latching, the shaped elements, in interaction with metallic springs and shaped elements of the housing, holding the solenoid on a housing axially and against rotation, and the springs being tensioned upon rotation of the housing during the installation, and the seal which seals the radial gap between the solenoid and the housing being coordinated, by means of the configuration thereof, with a small axial installation force.
Claims12
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.
A proportionally acting solenoid system for securing a solenoid within a bore in a housing comprising:
- a plastic encapsulation having a fastening flange integrally formed thereon and containing first shaped elements that are configured to interact with second shaped elements of the housing, each of the first shaped elements having an integrally formed bevel;
- springs configured to be coupled to the second shaped elements of the housing, each spring formed from metallic sheet metal;
- and
- a seal configured to seal a radial gap between the solenoid and the housing with a small axial insertion force;
- wherein upon interaction of the first shaped elements with the second shaped elements by axial pressing in and rotating of the solenoid, the integrally formed bevels of the first shaped elements engage the springs to provide axial pretensioning for mounting of the solenoid and resilient latching for holding rotational position of the solenoid, 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 upon engagement of the integrally formed bevels.
