Abstract:
1. An overheating protection device for electrically coupling an electrical power source to a fluid propulsion device, the fluid propulsion device including a propelling member within a manifold for pressurizing a fluid, the propelling member keying with a motor, the overheating protection device, comprising: a housing including a back plate, a top plate, a bottom plate, a first side plate and a second side plate for defining a cavity; said back plate, said top plate, said bottom plate, said first side plate and said second side plate defining an aperture; a thermostat switch positioning within said cavity and electrically coupling between the electrical power source and the motor; a cover engaging said aperture for sealing said thermostat switch within said housing; said cover including a bore for relieving said thermostat switch; a thermo-conductive layer having an interior surface and an exterior surface; said thermo-conductive layer engaging within said bore and said interior surface of said thermo-conductive layer contacting with said thermostat switch for conveying thermo energy between said thermo-conductive layer and said thermostat switch; said exterior surface of said thermo-conductive layer engaging the manifold for conveying thermo energy between the manifold and the thermo-conductive layer; and said thermostat switch terminating the electrical power to the motor upon said thermostat switch sensing thermo energy below or above a predetermined temperature range to prevent damage to the fluid propulsion device.
