A coil assembly (100) for an electromagnetic actuator (10) of a fluid injection valve (1) is disclosed. It comprises a solenoid (110) having a central axis(C), a first permanent magnet (120) and a second permanent magnet (130). Further, a fluid injection v...

A valve assembly (11) for an injection valve (100) comprises a valve body (14) including a central longitudinal axis (L), wherein the valve body (14) comprises a cavity (18). Furthermore the valve assembly (11) comprises a valve needle (20) axially moveabl...

The component has a magnetic core (1) provided for direct or indirect control of an injection valve member, and a recess (2) arranged for receiving the magnetic core wound with a solenoid coil (3). A lifting-motion armature (4) interacts with the coil and ...

An injector for the injection of fuel in diesel motors by means of the system "common-rail" that avoids the possibility of leak of fuel because of the waste, long term, of the seat of the needle of the injector. The rotary valve of the injector is actuated...

The moving components of the injectors are controlled by a stepper motor (1) which in its turn responds to pulses coming from the Electronic Control Unit (ECU) (2). To achieve more cycles for each revolution of the high-pressure supply pump, the pump has t...
