Abstract
An electromagnetic induction apparatus includes a tank having a bottom plate and containing an electrical device which vibrates during operation. The tank is supported by supporting members disposed between the tank bottom plate and a floor surface to define spaces therebetween. Sound suppressing members are disposed in the spaces defined between the support members, the tank bottom plate, and the floor surface. The sound suppressing members absorb sounds generated within the spaces and prevent air within the spaces from resonating during vibration of the electrical device.
Claims3
An electromagnetic induction apparatus comprising:
- a support surface;
- a tank having a bottom surface and containing an electrical device;
- a plurality of support members attached to the bottom surface of the tank and supporting the weight of the tank on the support surface, the support members defining a chamber between the bottom surface of the tank and the support surface;
- a sound suppressing plate having top and bottom surfaces and disposed in the chamber between the support surface and the bottom surface of the tank substantially parallel to and spaced from both the bottom surface of the tank and the support surface;
- and
- a plurality of support plates extending from the top and bottom surfaces of the sound suppressing plate and supporting the sound suppressing plate above the support surface.
