Abstract
A valve substantially comprising a first tubular body having a wall of substantially constant thickness in which is formed at least a pair of openings; a second annular body incorporating an electromagnet and presenting a pair of radial projections, and a block forming a seat for an electric connecting element connected to the electromagnet, the projections being designed to fit inside the openings in the first body; and a third body defining an axial sleeve designed to fit inside the electromagnet for forming a core, and an annular collar projecting radially from the sleeve and designed to fit inside the wall of the first body.
Claims15
An electromagnetic fuel metering and atomizing valve for a fuel supply device, comprising a plunger (1) for controlling fuel flow through a fuel injection orifice (2);
- said plunger (1) being activated by a core (3) energized by an annular electromagnet (4);
- characterized by the fact that it comprises:
- a first tubular body (5) formed by means of permanent deformation and having a wall (6) of substantially constant thickness;
- a top portion (8) of said wall (6) presenting at least one pair of openings (7);
- a second annular body (10) incorporating said electromagnet (4), and which presents a pair of radial projections (11), and a block (12) forming a seat (13) for an electric connecting element (14) connected to said electromagnet (4);
- said block (12) projecting from one of said projections (11), and each said projection (11) being inserted inside a respective opening (7) in said first body (5);
- a third body (15) defining an axial sleeve (16) designed to fit inside said electromagnet (4) for forming said core (3);
- and an annular collar (17) projecting radially from said sleeve (16) and designed to fit inside said top portion (8) of said wall (6) of said first body (5) and over said second body (10);
- means (18) for securing said third body (15) in a predetermined axial position in relation to said first body (5).
