Abstract
Reciprocating electromagnetic micro-pump, particularly for small electrical appliances, whose pumping chamber is defined by a tubular element, movable axially, against the action of a contrasting spring, between an advanced position of normal operation of the pump and a retracted position in which the outlet fitting of the pump is placed in communication with the cavity of the hollow body within which is movable in reciprocating fashion the core bearing the piston and which in turn communicates with the inlet fitting of the pump, in such a way as to absorb and anomalous overpressures generated, in operation, downstream of the pump.
