Anchor body i.e. armature body, for electromagnetic pneumatic valve, has inner cavity connected with external cavity through connecting web for receiving elastomer, where external and internal cavities are formed with recess for elastomer

摘要

The body (10) has a cavity for receiving an elastomer that is connected with a valve seat. The cavity is divided in to an external cavity (12) and an internal cavity (14), where diameter (da) of the external cavity is greater than diameter (di) of the internal cavity. The inner cavity is connected with the external cavity through a connecting web (16) for receiving the elastomer. The external and the internal cavities are formed with an annular recess (18) for the elastomer, where the anchor body is made of a permanent magnetic material or a ferromagnetic material. An independent claim is also included for a method for manufacturing an anchor body.
