Assembly for cooling and dampening vibrations of a unit mounted therein

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.
