Abstract

The invention relates to a paraffin type thermostat. The paraffin type thermostat comprises a main valve 1, a cover and seal gasket assembly 2, an upper support 3, a rubber pipe 4, a valve seat 5, a vent hole 6, a lower support 7, paraffin 8, an inductor 9, a bypass valve 10, a central rod 11 and a spring 12. The upper support, the lower support and the valve seat of the thermostat are riveted into a whole. The upper end of the central rod is fixed to the center of the upper support. The lower portion of the central rod is inserted into a central hole of the rubber pipe. The lower end of the central rod is conical. A cavity between the rubber pipe and a shell of the inductor contains the paraffin. The upper portion and the lower portion of the shell of the inductor are provided with the main valve and the bypass valve which are in linkage. The vent hole is formed in the main valve. The paraffin type thermostat is high in heat conductivity and guarantees that an engine cannot be excessively cold.
