Abstract

One describes a housing (11 ) for the control electronics(2) of a brushless direct current motor coupled to a fuel pump (9), the housing (11 ) containing a control integrated circuit (2) and being -sealed from the external environment, wherein the housing (11 ) is composed by a metallic basic housing (10), constituted by a metallic base (1) and a metallic cover (5), both being joined in a fluid-tight manner (7) to each other over their whole outer perimeter and by an over-molding (8), where there are electric contacts (4) for the pump and electric contacts (3) for the harness. Said housing (11) is positioned in a detachable manner outside the fuel pump (9).

Claims

8AMENDED CLAIMS Received by the International Bureau on 12.11.2010 (12.11.2010)
1. A housing for the control electronics of a brushless direct current motor coupled to a fuel pump (9), the housing (11) containing a control integrated circuit (2) and being sealed from the external environment, the housing (11) is composed by a metallic basic housing (10), constituted by a metallic base (1) and a metallic cover (5), both being jointed in a fluid-tight manner (7) to each other over their entire outer perimeter by means of electric contacts (4) for the pump, by electric contacts (3) for the electric harness and by an over-molding (8), said housing (11) being positioned in a detachable manner outside the fuel pump (9), the over-molding (8) being provided at the lower end of the housing (11), where it is engaged and/or fitted into the pump connectors of the contacts (4) of the pump, and has a shape providing support for the housing of the pump (9).
2. A housing according to claims 1 , wherein the joining (7) between the metallic base (1) and the metallic cover (5) of the basic housing
(10) is made by welding.
3. A housing according to claims 1 , wherein the joining (7) between the metallic base (1) and the metallic cover (5) of the basic housing (10) is made by folding. 4. A housing according to claims 1 , wherein the electric contacts
(3,
4) are sealed from the environment by glass rings (6).
5. A housing according to claim 1, wherein the metallic basic housing (10) is constituted by a metallic base (1) made of mechanical- construction steel, coated with nickel or tin, and a metallic cover (5) made of stamped stainless steel.
6. A housing according to claim 1 , wherein the electric contacts (4) are welded to coated FeNi connectors.
7. A housing according to claims 1 , wherein the over-molding (8) is made with plastic of high chemical resistance.
8. A housing according to claim 7, wherein the plastic may be polyphenylene sulfide (PPS), polyoxymethylene (POM) or polyamide (PA).
