The device comprises a housing formed by a cup-shaped body and a bell-shaped cover secured to the body, a deformable membrane secured to the housing and forming, together with the body, a chamber for the fuel, a movable shutter member designed to bring the chamber into communication with an outlet opening; the device is characterized in that at least one hole is provided in the base wall of the body for the inlet of the fuel into the chamber and a bearing seat for a sealing ring arranged so that it can be interposed between the seat and a corresponding seat of a housing in which the lateral wall of the body is inserted is provided on the lateral wall of the body.

Pressure regulator device for the fuel circuit of an internal combustion

A valve comprising a body having a cylindrical sliding seat and an opening for the passage of air; a plunger sliding axially inside the aforementioned seat, for regulating the aforementioned air supply opening; and an electromagnet, the core of which presents a rod fitting through an axial hole on the plunger. According to the present invention, the plunger is connected elastically to the rod by means of two springs, each designed to exert elastic force on the plunger in the opposite direction to that of the other spring; regulating means being provided for enabling predetermined preloading of both springs.

Electromagnetic air control valve for an internal combustion engine fuel

The pump comprises a casing in which is disposed a stator armature of an electric motor, a rotatable shaft to which is fixed a rotor winding and which is torsionally connected to an impeller rotor of the pump and a pair of covers which close the ends of the said casing and define between them a chamber within the casing for the fuel; a first end of the rotatable shaft is supported by a first seat formed within a cavity of a sleeve of a first cover projecting axially from the inner surface of the cover itself and the second end of this shaft is supported by a second seat formed in the second cover.
