ABSTRACT:
The device comprises an electromagnet with a coil (2) and an armature (3) mobile by the action of the magnetic flux produced by the coil (2). The armature (3) is slidingly housed in a seat (6) in a guide body (4) and is preferably hollow, it being guided on a portion of a pin (11) which penetrates into the seat (6) and is fixed to the guide body (4). The pin (11) can comprise variously arranged channels (14-18) which can be connected together or closed by the armature (3) when in its various positions, to hence form various types of electrohydraulic valves. The compact structure and the minimum masses involved result in a high frequency response and small electrical operating power. The device can be incorporated into a module which also contains the electronic part for controlling the valve in accordance with a position transducer associated with a control element positioned within the module, the control element being operated to control for example power stages.
