Injection valve
The functioning of the pump is insured by the action on the piston (C) of
the spring (B) and the electromagnet (A). In fact, the electromagnet, that
receives the electric impulses from the electronic circuit of the pump, puts
in movement the piston that is recalled in its initial position by the spring.
In such movement the piston drags with itself the membrane in teflon (D)
climbed on it, producing, because of the opening and closing of the
suction (E) and delivery valve (F), the expulsion of the present liquid
inside the pump head.
