Abstract

Abstract A valve comprising a cylindrical supporting body (1) having a first axial cavity (3) housing an electromagnet (4) and a core (7), and an axial hole (5) communicating with the cavity (3) and housing an anchor (8) integral with a mobile plugging member (9); and a nozzle (12) secured to the supporting body (1) and in which is formed a fuel outlet hole (13) controlled by the aforementioned plugging member (9); characterised by the fact that the supporting body (1) presents a series of holes (25) designed to enable external communication, through the lateral surface (2) of the supporting body (1), of the axial hole formed inside the body (1) itself.

Claims Analysis

Total Claims: 6

Claim 1

Independent Claim 190 words

1) - An electromagnetic fuel metering and atomizing valve for an internal combustion engine fuel supply device, said valve substantially comprising: . a substantially cylindrical supporting body (1) having a first axial cavity (3) housing an electromagnet (4) and a core (7), and an axial hole (5) communicating with said first cavity (3) and housing an anchor (8) integral with a mobile plugging member (9); . a nozzle (12) secured to and projecting axially from said supporting body (1), and in which is formed an outlet hole (13) communicating with said axial cavity (3) and controlled by said plugging member (9); said plugging member (9) being moved, by virtue of said electromagnet (4), between a first closed position, wherein it is pushed by a spring (20) against a seat (24) on said nozzle (12), thus closing said outlet hole (13), and an open position wherein said outlet hole (13) is opened; characterised by the fact that said body (1) presents a series of holes (25) designed to enable external communication, through the lateral surface (2) of said supporting body (1), of said axial hole (5) formed inside said body (1).

Claim 2

Dependent Claim 190 words

Claim 3

Dependent Claim 35 words

2) - A valve as claimed in Claim 1, characterised by the fact that said series of holes (25) consists of radial holes coming out inside said first cavity (3) on said supporting body (1).

Claim 4

Dependent Claim 60 words

3) - A valve as claimed in Claim 1 or 2, characterised by the fact that provision is made between said supporting body (1) and said nozzle (12) for a spacer (18) supporting said nozzle (12) and having a radial slot (30) for connecting said axial hole (5) in said body (1) to said seat (15) on said nozzle (12).

Claim 5

Dependent Claim 44 words

4) - A valve as claimed in one of the foregoing Claims, characterised by the fact that said plugging member (9) is integral with a rod (14) sliding axially inside an axial hole (15) on said nozzle (12) and connected to said anchor (8).

Claim 6

Dependent Claim 40 words

5) - A valve as claimed in one of the foregoing Claims, characterised by the fact that said anchor (8) and said core (7) present radial holes (31, 32) for enabling external communication of the cavities formed inside the same.
