APPARATUS FOR STARTING HEATING Russian patent published in 1994 - IPC

FIELD: engine engineering. SUBSTANCE: apparatus has heater for coolant of a cooling system made of relay 22 provided with winding and control mechanism connected to a circuit for switching heater 26 by using a control unit made of temperature gauge 21, fluid pump 6 provided with electric motor 37, electromagnet valve 3 with winding, two alarm lamps, and central switch 30 with contacts 32,33,35,36. The apparatus is provided with pickups 43,38 of minimum level of coolant having inlets and outlets and provided in tank 2 and cooling system correspondingly. Pickup 38 is connected to electric motor 37 of pump 6, winding of electromagnet cock 3 and contacts 36 of central switch 31 by its inlet and to alarm lamp 40 and winding of relay 39 by its outlet. Inlet of pickup 43 is connected to contacts 32,36 of central switch 31 and outlet of the pickup is connected to alarm lamp 44 and winding of relay 42. Central switch is connected with electric motor 37 of pump 6 through contacts 45 of relay 39. Coolant is pumped from radiator 10 to tank 2 through units 9,11,12,8,3 by using pump 6. The tank is a Thermos. Temperature of fluid is maintained by heater 26 which is controlled by temperature gauge 21. Before starting fluid is pumped from tank 2 trough units 3,8,12 to a cooling jacket of cylinders 13 by using pump 6 and heats engine 1. EFFECT: enhanced reliability. 4 dwg
