Abstract

914,760. Cooling dynamo-electric machines. SCANDINAVIAN AGENCIES CORPORATION Ltd. June 9, 1960 [July 22, 1959], No. 20360/60. Class 35. [Also in Group XXVI] An electric motor driving a bilge pump is cooled by the liquid being pumped and, if this liquid flow ceases, valves open and air is forced through the system to prevent overheating. Motor 10 with pump impeller 12 keyed to its shaft 11 is enclosed in a cylindrical outer casing 15, spaced from the motor to leave a cooling duct 16 through which the pumped liquid passes from impeller 12 to outlet 18. The liquid in which the pump stands is admitted to the impeller through grill 19. In the wall of casing 15 (or in outlet pipe 18, close to the pump unit) is an outlet 24 which is normally closed by a valve comprising poppet head 25 and stem 26, the liquid pressure in the cooling duct being sufficient to overcome the force due to spring 27. When the liquid level falls below grill 19 the valve opens and air is pumped through cooling duct 16 to outlet 24. Additional valve-controlled outlets may be provided round the circumference of the outer casing, and the valves may be operated by a temperature-responsive device instead of by liquid pressure.
