(57) A device is described, for intercepting the flow of a fluid that passes through a
distributing circuit (4,6), in particular of a washing machine, where the said device
(10) comprises
- an actuator (15) presenting a displacement organ (15A) capable of working in two opposite
directions, said displacement organ (15A) being able to move a movable shutter member
(14) until the latter reaches at least a first working position,
- striker means (AP,AP') that follow the movement of said shutter member (14) and capable
of coming into contact with respective fixed stopping surfaces (18A,18B), the contact
of said striker means (AP,AP') with a first of said stopping surfaces (18A,18B) corresponding
to the attainment by said shutter member (14) of said first working position.
According to the invention, under constancy of power supply to said actuator (15),
the latter is capable of automatically inverting the direction of movement of said
displacement organ (15A), as a result of the effect, in particular the mechanical
effect, that the contact of said striker means (AP,AP') with one of said stopping
surfaces (18A,18B) determines on said displacement organ (15A).
