Abstract
Abstract An assembly is provided for use in cooling and dampening vibrations of an electronic fuel pump controller which is mounted on the body of a fuel pump, the latter being utilized in an internal combustion engine. The assembly comprises a housing having marginal portions secured to the exterior of the pump body so as to conceal the controller within the housing. A plurality of relatively spaced spacer means are disposed within the housing interior and resiliently retain a non-porous enclosure of the controller in a predetermined spaced relation with the housing interior surfaces. Ports are formed in the housing which communicate with the interior thereof. Gasket means of a resilient non-porous material is provided having an inner section sealingly secured in encompassing relation with a portion of the controller enclosure. The gasket means also includes an outer section outwardly spaced from the inner section and a continuous resilient mediate section encircling the enclosure portion and interconnecting the inner and outer sections. The outer section is sealingly secured in sandwiched relation between the housing marginal portions and the fuel pump body. The mediate section of the gasket means, the spacer means, and the housing interior surfaces coact with a substantial area of the exterior of the controller enclosure to form a chamber through which a coolant continuously circulates.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
234 words
An assembly for use in cooling and dampening vibrations of a unit when the latter is mounted on a heat-generating and vibrating supporting surface, said assembly comprising a housing having the interior portion for accommodating and concealing therein the unit, and external marginal portions projecting outwardly from the interior portion and being mountable on the supporting surface; relatively spaced resilient spacer means disposed within the housing interior portion and coacting with surfaces defining the housing interior portion and exterior surfaces of the unit for resiliently retaining the latter in a predetermined spaced relation with the surfaces defining the housing interior portion; relatively spaced ports formed in said housing and communicating with the interior portion thereof and through which a cooling medium is adapted to circulate; and a gasket means of resilient material, said gasket means including an inner section adapted to encompass and be sealingly secured to segments of the unit exterior surfaces disposed within the housing interior portion, an outer section disposed in outwardly spaced substantially encompassing relation with said inner section and adapted to be secured in substantially sandwiched sealing relation between the housing marginal portions and the supporting surface, and a continuous resilient non-porous mediate section interconnecting said inner and outer sections; said spacer means, housing interior surfaces, and said gasket mediate section coacting with a substantial area of the unit exterior to form a chamber for the circulating cooling medium.
Claim 2
Dependent Claim
234 words
An assembly for use in cooling and dampening vibrations of a unit when the latter is mounted on a heat-generating and vibrating supporting surface, said assembly comprising a housing having the interior portion for accommodating and concealing therein the unit, and external marginal portions projecting outwardly from the interior portion and being mountable on the supporting surface; relatively spaced resilient spacer means disposed within the housing interior portion and coacting with surfaces defining the housing interior portion and exterior surfaces of the unit for resiliently retaining the latter in a predetermined spaced relation with the surfaces defining the housing interior portion; relatively spaced ports formed in said housing and communicating with the interior portion thereof and through which a cooling medium is adapted to circulate; and a gasket means of resilient material, said gasket means including an inner section adapted to encompass and be sealingly secured to segments of the unit exterior surfaces disposed within the housing interior portion, an outer section disposed in outwardly spaced substantially encompassing relation with said inner section and adapted to be secured in substantially sandwiched sealing relation between the housing marginal portions and the supporting surface, and a continuous resilient non-porous mediate section interconnecting said inner and outer sections; said spacer means, housing interior surfaces, and said gasket mediate section coacting with a substantial area of the unit exterior to form a chamber for the circulating cooling medium.
Claim 3
Dependent Claim
50 words
The assembly of claim 1 wherein the spacer means and at least the gasket means mediate section are of resilient vibration absorbing material and the spacer means are mounted on and project inwardly from the surfaces defining the housing interior portion and resiliently engage exterior surface portions of the unit.
Claim 4
Dependent Claim
36 words
The assembly of claim 1 wherein the gasket means mediate section is adapted to separate the cooling medium chamber from a second chamber formed by the supporting surface and the remaining area of the unit exterior.
Claim 5
Dependent Claim
23 words
The assembly of claim 2 wherein the housing interior surface and the exterior surface of the unit are formed of substantially rigid material.
Claim 6
Dependent Claim
23 words
The assembly of claim 1 wherein the gasket inner section is substantially bonded to and conforms to exterior surface portions of the unit.
Claim 7
Dependent Claim
32 words
The assembly of claim 1 wherein at least one of the housing ports communicates with an inlet side of a fuel pump associated with a controller forming a component of the unit.
Claim 8
Dependent Claim
32 words
The assembly of claim 1 wherein the mediate section of the gasket means is provided with a bellows-like fold which is disposed in outwardly spaced substantially concentric relation with the inner section.
